A patient maths tutor, living in the family phone
OrchaHub teaches step by step inside WhatsApp or Telegram — the way a good teacher would. Grade 5 to A-Level, straight from the official Zimbabwean syllabi. Free to start. And anyone, anywhere in the world, can sponsor a student back home.
We're in an invite-only beta — message the tutor on either app and tap Request an invite to get your code.
A real style of exchange — hints first, answers earned.
No app to install. No timetable. Just chat.
OrchaHub lives inside the messaging apps Zimbabwean families already use, so tutoring fits around load-shedding, chores and school runs.
Send a message
Type a question, or photograph handwritten working straight from the exercise book. The tutor reads both.
Learn step by step
The tutor guides with hints, one step at a time — like a patient teacher, not an answer machine. Question difficulty adapts as mastery grows.
Parents see progress
Progress is tracked per child, per topic — so whoever pays the phone bill can see the learning actually happening.
Built from the official syllabi, primary to A-Level
Three Zimbabwean curricula, one tutor. Each student is taught at their own level.
Grade 5 Mathematics
Zimbabwe's primary maths for Grade 5, following the Heritage-Based Curriculum — gentle, encouraging and pitched for younger learners.
ZIMSEC O-Level Mathematics
Forms 1–4, the full road to the O-Level exam — from directed numbers to transformations, straight from the official syllabus.
A-Level Pure Mathematics
Forms 5–6 Pure Maths from the official syllabus, for students pushing towards university.
A tutor that shows its working
Verified maths, always
The tutor never guesses. Every computed answer is checked by a computer-algebra system before it's stated, and the practice bank holds 2,000+ verified questions.
Marks handwritten work
Students photograph their working and the tutor checks it — praising the right steps and catching the slip, not just the final answer.
Printable worksheets
Worksheets arrive as printable PDFs. Photograph the finished page and it's marked within minutes — practice that works even when data is tight.
One phone, six students
Built for how Zimbabwean families actually share phones: up to 6 named students on one number, each with their own tutor, history and progress.
School fees get paid from abroad. Now tutoring can be too.
Anyone can pay for a student. A parent in Harare, an aunt in Johannesburg, a brother in Leeds or Dallas — enter the child's number, pay by card or EcoCash, and their tutor is unlocked back home. Less than the cost of a coffee a week.
