Store rating from 3.8 to 4.6 in about two months

The challenge

Gymboss is an interval timer app for workouts like Tabata and HIIT. It already did its main job well, but reviews kept naming the same bugs and awkward screens, and the store rating stayed at 3.8. The app also asked for reviews at random times, so happy users were rarely asked at a good moment.

What we built

We read through user reviews to find what got in people’s way most, then fixed those bugs and reworked the screens where people got stuck. Workouts ran more smoothly and the app felt steadier day to day.

• Fixes for the bugs named most often in reviews
• Clearer screens where users had been getting stuck
• Review prompts shown only after successful use, with limits on how often they appear

How we worked

We started with the experience, not the rating. Once the app worked better, we made sure happy users were asked to share it at a good moment. The rating followed: from 3.8 to 4.6 in about two months.
