Eight logic puzzles. One calm app.
Crowns, Sudoku, Flow, Duo, Shikaku, Bonds, Equate and Blend, each with five difficulty steps that add reasoning, not grid size. Levels are generated from a seed, so everyone solves the same daily puzzle and the leaderboard compares like with like.
In closed testing on Google Play and TestFlight. Public release soon.
Log a migraine in seconds. See your own patterns.
A self-management diary for migraine and the menstrual cycle, built for the moment of an attack: Quick Save logs it in two taps, details can wait. Over time Naova shows patterns in your own data and prepares a clean report for your doctor. It is a wellness tool, not a medical device.

Draw something. It lands on their home screen.

Expenses, budgets and 150+ currencies, in sync.
Track expenses and income in seconds, set monthly budgets linked to categories, keep accounts in different currencies with live rates, and see where the money goes in reports and forecasts. The first version shipped on Google Play in Java with Firebase sync. The second is a Flutter rewrite for Android and iOS with local-first sync, shared spaces for families and AI-assisted capture of transactions from bank notifications.
A puzzle about dimensions, from a point to 4D.
The screen is split in two. Above, a world in N dimensions and a golden knife that slices it. Below, the slice itself, in N−1 dimensions, where your character lives. Move the knife and hidden rooms, tunnels and the exit appear in the slice, like a scan. The same mechanic takes you from a point on a line all the way to a four-dimensional world.
Coming to Google Play and the App Store.
If it looks connected, it is.
A little taxi that cannot turn carries passengers through worlds of impossible beams. The only real control is the camera: rotate and tilt until two roads look like they touch on screen, and then they do. From above, heights collapse and the taxi lifts onto a road that was never there.
Coming to Google Play and the App Store.
A factory for numbers.
Extract numbers from a map with no edge, carry them on belts through machines that add, multiply, divide and compare, and deliver what the hub asks for. The factory stays and grows: the farther you build, the bigger the numbers. Save your own machines as functions, solve a mystery machine every day, and build together with friends on the same map.
In development for Google Play and the App Store.
