- 💰 Revenue: Marginal — $0 - $500/mo · MICRO tier · indicative confidence, trajectory unclear.
- ⭐ Quality: 4.6★ across 39 reviews — weak — significant quality concerns.
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: Insufficient signal to assess trajectory.
- ⚠️ Risk: Low — no material risk signals detected.
🎯 For competitors: Mixed picture. Worth competing if you have a clear UX or pricing edge — otherwise crowded segment.
💵 For acquirers: Estimated asking range 18-32× monthly = $3K-$6K. Portfolio play ($6K/mo combined) commands premium.

📝 About this app
The Time Trainer app is a LOT MORE than a metronome. Yes it has all the features you need in a metronome: accent control, tempo, a flasher and a few different sounds, but it also contains 3 exciting tools to help you develop your time away from the metronome: Bar Breaks, Random Beat Drop and Speed Upper.
Practicing with a metronome is one of the most important exercises you can do but it is also essential that you develop your own internal time feel, which is what this App is designed for!
This app was designed by me, for me - and you :) And I'm sure you find it as useful as I do!!
