About
An Independent App Studio
Who We Are
MintWave Studio is an independent developer of small Android apps. Each app does one job: size a cable, count down to hatch day, track expiry dates, plan a daily budget or train rhythm-game timing. The calculators and trackers work offline without an account, and iPhone versions of several apps are in progress.
What We Build
- Calculators and trackers — Cable Calc, Hatch Day, Days Until, Daily Budget, MultiTimer
- Music practice — Rhythm Trainer for rhythm gamers and drummers
- Quick games — Shadow Match, Trivia Showtime, ZeroMargin, Steady Hand

App Highlights
What Every App Has in Common
02
No Account Needed
Open the app and start. There is no sign-up, and the budget and tracking apps never connect to your bank or a cloud service.
03
Free to Try
Every app is free to download. Pro upgrades are optional. MultiTimer, Days Until and Daily Budget have no ads; the games show occasional ads that Pro removes.
How Our Apps Stand Out
/01
Built From User Feedback
Features are picked by reading store reviews of our apps and of competing apps, then fixing what users complain about most.
/02
Checked Against Real References
Cable Calc follows IEC 60364-5-52, Hatch Day uses incubation data for 11 bird species, and Rhythm Trainer judges every tap to the millisecond.
About Us
Our Journey
Small Apps, Steady Updates
MintWave Studio started with simple Android utilities and games. The apps have since been rebuilt in Flutter, translated into up to 14 languages and paired with free web tools on this site, from a voltage drop calculator to a hatch date calculator.
