About MintWave Studio

MintWave Studio is an independent, one-person studio that makes small Android apps. Each app does one job well, works offline where it can, and never asks you to create an account.

What we make

The apps fall into four groups. See all apps for details and Google Play links.

• Tools and trackers: Cable Calc (cable size and voltage drop to IEC 60364), MultiTimer (many timers at once) and Days Until (expiry date tracker).
• Money: Daily Budget, a private daily spending planner with no bank connection.
• Hobbies: Hatch Day for egg incubation and Rhythm Trainer for rhythm-game and drum timing.
• Quick games: Shadow Match, Trivia Showtime, ZeroMargin and Steady Hand.

How the apps are made

New features are chosen by reading store reviews of our apps and of competing apps, then fixing what users complain about most. Calculators are built on published references: Cable Calc follows IEC 60364-5-52, and Hatch Day uses incubation periods, temperatures and humidity targets for 11 bird species. The apps are written in Flutter and translated into up to 14 languages.

Your data

The apps don't need an account, and the calculators and trackers keep your data on your phone. Some games show occasional ads, which an optional Pro upgrade removes. The privacy policy lists exactly what each app collects, and the terms and conditions cover purchases and use.

Free web tools

Several calculators from the apps are free on this site, including the cable size calculator, voltage drop calculator, hatch date calculator, dog pregnancy calculator and daily budget calculator.
