Koticha
● live on Google PlayA teacher's companion for Malawian primary schools -- score entry, ranking, and reporting, built by PsyByte Labs to work on a five-year-old phone with no signal.
A teacher with 160 learners and a pen as her ranking tool.
Every marked exam script means another row to total and another name to re-rank by hand. A teacher scoring 8 subjects across a full class can lose 4 to 6 hours a term to arithmetic -- and if a ranking error surfaces after the final sheet is written, the positions get redone by hand.
Koticha started from that one workflow, not from a feature list. It's the product that set PsyByte Labs' standard for everything since: find the task quietly costing someone hours every week, and build the narrowest tool that removes it, for hardware people actually have.
Same term, a fraction of the arithmetic.
Manual ranking, per term -- the old way
Koticha's target for 200 students, one subject
Calculation errors -- totals and positions are computed
80%+ time saved is Koticha's design target versus fully manual tallying, not yet a measured figure across a full term of real use.
Koticha is our own product -- designed, built, and maintained by PsyByte Labs.
It's free to install, doesn't need an account, and never requests network permission. The full feature list, in-app screens, and FAQ live on Koticha's own site -- this page is the short version of why it exists.
