Identity that works in school
Children sign in with cards, not email.
Student codes and four-digit PINs are printable, resettable, and easy to hand out during assembly or class.

Learning apps
for schools
and families.
Schools can assign Simu Primary, Simu JHS, vMaths, Simu Science Lab, and Stories App through the school workspace. Families can also subscribe directly for their children, with child access managed separately from school-owned data.
Free for schools The school operations suite is 100% free — schools only pay for the optional learning apps.
Learning leads
The student apps are the first thing families and schools see.
Ops supports
Admin, finance, portals, and teacher tools stay behind the same identity layer.
§ 01 — The platform
The boring bits, done properly.
Schools are not start-ups. They cannot afford a half-finished SSO library, manual billing held together by email, or an authorization story written on a napkin. Simusim is the platform layer your IT department would have built — if you had an IT department.
No. 01
One identity,
four front doors.
Students with a code & PIN. Parents on a phone. Teachers on a phone. Admins on email. Each role gets the front door it deserves — never the one IT thought was cute.
- School-routed login.
login.simusim.com/<your-slug>shows your crest, your colours, your students. - Printed cards. Bulk-import a class, print scissors-line login cards, hand them out on Monday.
- SSO across every app. One sign-in → gradebook, attendance, lab, all of it.
No. 02
One authorization
service, no exceptions.
Every can-this-person-do-this-thing question goes through one engine. No copy-pasted middleware. No "well, this admin screen forgot to check." The cost of a check is microseconds; the cost of a leak is your school's reputation.
- Belt & braces. API checks the role; the database checks the tenant.
- Row-level security. Postgres physically prevents your data from touching another school's.
- Audit log, always. Who did what, to whom, when, from where.
No. 03
One billing log,
no surprise lockouts.
The operations suite is free for schools that onboard their students — you only pay for the optional learning apps. And we don't make schools fight a credit-card form: pay by bank transfer or mobile money; platform staff records it; your access updates from the source of truth. Grace periods and reactivation are built into the subscription state machine — not negotiated by email.
- Grace period, not guillotine. Falling behind dims your apps; it never deletes your data.
- Mid-term reactivation as soon as platform staff records the cleared payment.
- Per-app entitlement toggles. Platform staff can enable the apps your school is meant to use; the rest stay off.
Daily staff workflow
Teachers do the day's work in one place.
Roll call, gradebook, lesson plans, and CBT sit together so staff are not jumping between tools.
School finance
Fees and receipts live with the school record.
Bursars can see collections, balances, approvals, receipts, and reports without leaving the workspace.
§ 02 — The app suite
Student apps first, school ops connected.
The Simusim app suite shares the same identity, authorization, and tenancy foundation, but the learning products take the front row. Platform staff enable school-level app entitlements; school admins assign the right apps to the right people; the launcher sends each role to the surfaces they actually use, including face recognition for attendance marking where a school enables it.
The learning layer
The reason to care is what students get to use.
Simu Primary, vMaths, Stories App, Simu JHS, and Simu Science Lab sit in front. The school workspace still matters because it gives those apps clean identity, class assignment, permissions, payments, and support around them.
01
Simu Primary
For Primary 1–6
Maths and Science across the NaCCA primary curriculum, with playful interactions designed for shared classroom devices.
02
vMaths
For visual maths practice
Guided visual mathematics lessons with fraction bars, number lines, shapes, and practice packs students can manipulate.
03
Stories App
For reading
A student reading shelf with levelled stories, progress, and illustrated reading experiences that make literacy feel alive.
04
Simu JHS
For JHS 1–3
Junior-high curriculum coverage with diagnostic quizzes, BECE-style practice, and topic mastery that students can see.
05
Simu Science Lab
For Science
A virtual science lab. Build circuits, watch refraction, set up experiments, and observe results without waiting for equipment.
06
Student Portal
For students
One hub. Today's classes, due quizzes, last term's grades, and quick launches into the learning apps assigned to each student.
07
Parent Portal
For parents · phone-first
Attendance, grades, and the day-to-day at a glance — designed for parents who'll mostly check this on their phone, on slow networks.
08
Teacher Portal
For teachers
A teacher's day, in one screen: take attendance, grade work, post a lesson plan, launch a CBT — without four tabs and three logins.
09
School Admin
For school operations
Users, classes, rosters, parent-child links, PIN resets, credential cards, and per-user app assignments from one school-scoped console.
10
Finance
For bursars & admins
Fee structures, invoices, collections, receipts, waivers, trial balance, and student statements with a finance gate separate from classroom roles.
11
Face Recognition
For attendance marking
Optional face recognition for attendance marking at the gate or in class, with teacher review, manual fallback, and school-controlled use.
12
Gradebook
For subject teachers
Assignments, scores, term reports. Grade-weighting that matches your school's curriculum — not a curriculum that matches the software.
13
Lesson Plans
For teachers & heads
Author, submit, approve. Drafts to the head teacher; approval workflow built in. Print-ready lesson notes, every Friday.
14
CBT
For exam papers, online
Author quizzes once, deliver to the whole class, auto-grade multiple-choice answers. Built for the classroom, not the exam hall.
School apps share SSO. No separate logins.
Entitlements, role gates, and per-user assignments decide what each person sees.
Separate from school workspaces: Simusim Family lets parents create an independent family tenant, add children, and manage fixed-term access to Simu Primary, vMaths, Simu JHS, Simu Lab, and Stories App without receiving school-owned data.
§ 03 — The learning apps
What students actually open.
The Simu learning suite turns a Simusim workspace into a place children come back to: Simu Primary for Basic 1–6, Simu JHS for the BECE years, and Simu Science Lab — a virtual science lab built from the ground up for the NaCCA curriculum. vMaths gives guided visual maths practice, and Stories App gives students a reading shelf inside the same platform.
Simu Primary · Basic 1–6
Maths & Science
for the NaCCA primary years.
Hands-on lessons that map one-to-one to NaCCA Basic 1–6 indicators. Built playful, dense with simulations, and designed for the kind of shared classroom tablet a real Ghanaian school has — not a Chromebook in a Bay Area lab.
- Real NaCCA mapping. Every lesson tagged with the official Basic-school indicator code — from B3.1.1.1.1 to fractions, to the water cycle.
- Ghanaian contexts. Cedi & pesewa, trotro, market, rice, cocoa. The maths feels local.
- Offline once downloaded. Lessons cached on first run; works through dropped connectivity.
- Stories, games & rewards. Daily goals, streaks, and a mascot that does not say "great job" sixty times an hour.

Simu JHS · B7–B9 / BECE
For the BECE years,
by the BECE syllabus.
Maths and Integrated Science across all four strands of B7–B9. Diagnostic quizzes, mastery tracking, and BECE-style practice with structured working — designed for students who'll sit a real, paper-based exam.
- Every indicator, every strand. All four Maths strands (Number, Algebra, Geometry, Data) plus all five Science strands — tied to the official NaCCA CCP 2020 codes.
- BECE-style working. Practice with the structured working the markers expect — not just multiple choice.
- Mastery, not points. Calm voice: "Correct" / "Not quite". Mastery indicators per topic. No empty praise.
- Weakness clinic. The system finds the indicator a student keeps missing and sends them to the right lesson, not the next lesson.

Simu Science Lab · Virtual science
A real science lab
that runs in a browser tab.
A virtual lab for the experiments most Ghanaian schools cannot afford to run on bench: build circuits, watch refraction, separate the food groups, set up the water cycle. A built-in tutor is grounded in the active experiment and offers hints, recap checks, and chat.
- 130+ NaCCA-mapped experiments. Circuit Builder, States of Matter, Refraction & Dispersion, Water Cycle, Cell Types, Energy Transformation — tagged to B7–B9 Integrated Science strands.
- Real interactivity. Drag components, change values, watch what happens. No videos pretending to be lessons.
- AI tutor inside the lab. Uses experiment facts, misconceptions, and objectives to ask Socratic questions and stay on curriculum.
- Designed for low-end devices. Each experiment in its own bundle — home page doesn't load every sim's weight.

§ 04 — The people
Four humans, four front doors.
A five-year-old cannot remember a strong password. A grandmother does not own an email address. A teacher does not have time to receive a magic link. We do not treat humans like undifferentiated "users" — the front door fits the person walking through it.
Persona — Student
The student.
Children sign in with a school-issued code and a four-digit PIN. No email. No phone. No password they'll forget.
- IdentifierKMP-7H2P9X — school-prefixed, six chars, no ambiguous glyphs.
- Credential4-digit PIN. Randomly generated at enrolment. Resettable by the school admin.
- Lockout8 attempts ➜ 30-minute auto-unlock. Audit-logged.
- Lands inStudent Portal, with the learning apps assigned to their class.
Designed for shared classroom devices & school tablets
- No email required. Students use a school-issued code and PIN.
- Easy to distribute. Cards can be printed for a class or a whole school.
- Resettable by admin. Lost cards do not become a support crisis.
Persona — Parent / Guardian
The parent.
Adults sign in with the phone number the school already has on file. No app store install. Mobile-first, low-bandwidth, works on the kind of phone parents actually own.
- Identifier+233 24 *** **41 — phone numbers in E.164, always.
- Credential4-digit PIN. Delivered to the parent in writing at enrolment.
- Linked toOne or many children at the same school, with the link recorded by the admin at enrolment.
- Lands inParent Portal: attendance, grades, updates, the day-to-day — a calm, mobile-first view of their child's week.
Optimised for the phone & the bus ride home
- Built for phones. Parents can check the school day from a normal mobile device.
- Clear child context. Each update is tied to the child and class.
- No app-store step. The portal works from the school login path.
Persona — Teacher
The teacher.
Teachers sign in with their phone & PIN, land on Today, and run their day in one place. Attendance, grades, lesson notes, a CBT to launch — no four-app shuffle.
- IdentifierPhone number — the one already on the staff roster.
- Lands inTeacher Portal · Today — their class roster, their lessons, their open quizzes.
- OwnsThe classes they lead. Authorization knows it; no admin-screen exceptions.
- MobileAll-day mobile. Roll call from the back of class, in seconds.
Built for the actual rhythm of a school day
- Fast roll call. Teachers can mark attendance from the back of class.
- One staff surface. Lesson work, scores, and CBT sit together.
- School-scoped access. Staff see the classes and students they are allowed to handle.
Persona — School Admin
The school admin.
The head teacher, the registrar, the IT lead. They onboard staff, import students from a spreadsheet, link parents to children, and print credential cards — from a real admin app, not a Google Sheet.
- IdentifierEmail + password, with TOTP MFA strongly encouraged.
- AuthorityScoped to their school. No other school's data ever shows up — not even by accident.
- ToolsBulk import, parent ↔ child linking, PIN resets, per-user app assignments.
- Lands inSchool Admin app — the workspace seen in the hero, above.
For the operations of a real, living institution
- Bulk import first. Start from the roster schools already maintain.
- Parent links included. Guardians connect to the right children during setup.
- Cards ready to print. Credentials leave the system as something a school can hand out.
§ 05 — Security & tenancy
Quietly uncompromising.
Schools handle the data of minors. We treat that as the responsibility it is — with a model that physically prevents one school's data from touching another's, even if we wrote a buggy query. Belt, braces, and a third belt for good measure.
-
I.
One org per school. Always.Every row in the database is stamped with an
org_id. Every query is filtered by it. PostgreSQL row-level security enforces this at the engine level — not just the app. There is no "shared" data because there is no shared data. -
II.
Authorization, twice.At the API edge: "is this user allowed to call this endpoint?" At the data layer: "does the row they're touching belong to their school?" Either failing aborts the request. We don't trust a single check with the data of children.
-
III.
PIN-aware lockout.A 4-digit PIN is, by maths, weak. So Simusim treats every failed PIN attempt as serious: 8 strikes lock the account for 30 minutes, every attempt is logged, and school admins can review login activity for their org.
-
IV.
Entitlements live outside the token.A lapsed subscription doesn't wait for tokens to expire. App access is checked against the Platform API at session start, so overdue or reactivated schools follow the subscription state without stale token claims.
-
V.
Audit log, by default.Key account, payment, entitlement, and parent-child relationship changes are written to the audit log with who, when, from where, and what changed.
§ 06 — Built for reality
For schools as they actually are.
Most school software is designed for a school that doesn't exist — one with unlimited bandwidth, parents on iPads, and an IT department in the basement. Simusim is built for the school that has none of those things and still needs to run a tight ship.
¶
PIN-first, by design.
Four-digit PINs are not a compromise — they are correct for who's using them. Children, grandparents, and tired teachers shouldn't be locked out by a password policy from a 90s bank.
‖
Mobile is the desktop.
Every screen assumes a parent on a mid-range Android, on 3G, on a bus. The platform-admin and school-admin sides are dense and desktop-ready. The portals are gentle and phone-ready. Same data, different doors.
✂
Paper still matters.
Login cards print on A4 in pre-cut grids. Term reports print to PDF without a designer's intervention. Class lists are made for the photocopier on the corridor.
₵
Free ops, bank-pay for apps.
The operations suite is free for schools that onboard their students; you only pay for the optional learning apps — how schools pay: bank transfer, mobile money, the occasional cheque. We log the payment, we don't gate it on a Stripe webhook. Local realities, properly respected.
Designed around school habits
Digital where it helps. Paper where it still works.
Simusim does not assume every child has email, every parent installs an app, or every school has an IT officer. It supports printed login cards, phone-first portals, and optional gate check-in without breaking the same identity model.
§ 07 — Onboarding
From spreadsheet to pilot workspace setup
in under fifteen minutes.
Our staff onboards your school personally. In a focused setup call we configure your slug, validate your roster, generate PINs, and prepare a print-ready stack of login cards. Card distribution and the first sign-in happens on your school's timeline — we're on the other end of every question.
I
Tell us about your school.
Name, slug, country, term start. A short setup form, with Ghana-first defaults for phone numbers, currency, and primary & JHS school levels.
Workspace provisioned
II
Upload your roster.
One spreadsheet. Students, parents, teachers, the parent ↔ child links. We validate the data, dry-run the import, and let you fix the broken rows in place.
Users created
III
Generate credentials.
We mint a unique code & PIN per student. Parents get a printed PIN letter delivered with their child's card. Teachers get a phone-PIN walkthrough. Admins pick their password & enable MFA.
Credentials issued
IV
Print & go.
Login cards exported as a single PDF, eight to a page. Apps assigned to classes. We send you a Monday-morning sign-in test you can do with a kid in five seconds.
Ready for pilot use
Every onboarding is done in a real call with Simusim staff. We do not believe in self-serve for institutions that handle children.
§ 08 — Sign in
Same platform, the right front door.
Pick who you are. Each door opens the correct sign-in for your school — or, if you bought Simu for your own family, your family account.

Use subject: Application - Customer Success & School Support Associate
Work close to the problem.
You will see how heads, bursars, teachers, parents, and students use what you ship. That feedback changes the roadmap quickly.
Build for constraints that matter.
Low-end phones, patchy data, printed credentials, school fee realities, and child-safe identity are not edge cases here. They are the brief.
Own visible pieces.
The team is small. Good work does not disappear into a backlog; it becomes part of the platform schools run on.
