Stopby
ProductivityReminders tied to the places you already go, not to a clock. Arrive at your pharmacy and "collect your script" is waiting on your lock screen — and your location never leaves your phone.
Coming soon AndroidiOS
Honest Km
ProductivityAn automatic kilometre logbook for cars that aren't fully yours — rentals, company cars and leases. It logs your trips in the background, watches rental km limits, keeps your receipts, and exports records ready for a reimbursement claim.
Coming soon AndroidiOS
Which Box
ProductivityA storage inventory app for your garage, storage unit or records room. Log what's in every box, print QR labels, scan one to see what's inside, and get a prompt to update the list when you arrive or leave.

How we work
Three things we refuse to compromise on
Small apps, done properly
Each app solves one problem completely rather than ten problems partially. Fewer settings, fewer taps, no dark patterns.
Privacy by default
No advertising SDKs and no third-party trackers. Every app publishes exactly what it stores and how to delete it.
Built to be maintained
Tested calculation cores, documented backends and real release processes — so an app still works two years after launch.
Have something you want built?
We take on a small number of client projects alongside our own products.
