A small software studio · Cape Town & remote
Apps that earn a place on your home screen.
NK Software is a small studio designing and shipping private, country-aware products — apps that earn their keep without shouting for your attention. Makers of Kiduvo.
01 —The studio
Small enough to care, deliberate enough to ship.
02
Country-aware
Software that knows where it is. Local schedules, local schools, local payment rails — built in South Africa first, with sensible defaults everywhere else.
03
One thing, well
We work on one engagement at a time. The team you brief is the team that ships — no handoffs, no juniors learning on your dime, no surprises in week ten.
02 —Selected work
Kiduvo — a private health record for every child.
Retiring the paper folder under the bed.
Kiduvo is the complete health record every parent eventually wants — vaccines, illness, medications, growth, milestones and every doctor's letter, in one private, country-aware app.
We took the project from sketch to closed beta on Google Play in under a year — with row-level security on every record, curated South African vaccine schedules, family sharing, and one-tap PDF summaries that doctors actually read.
