A few months ago, I came across this (now deleted) post about someone who worked at a hotel and noticed a flaw in the hotel's software. They ended up building a plugin to fix it... and made a nice side income from it. That got me thinking: How many other tiny or overlooked mobile app issues are lurking out there, waiting for a solution?

I wanted to help skip the guesswork so looking at negative reviews would highlight problems users would be having. If a solution was prominent enough, these users would likely convert or at least download an alternative app to make their life easier. I basically analyzed over 50k negative reviews across around 5000 mobile apps on the App Store and Play Store to find specific improvements that can be made on existing apps that can potentially be made into a competitor for existing mobile applications.

I used AI to analyze the negative reviews and find user problems and provide potential improvements to the existing apps as a competitor or even a better alternative.

I separated by categories and by app and highlight app/software specific problems users were having as well as category specific problems.

If you're building (or improving) a mobile app, this database might save you a ton of guesswork.

We scraped apps from 160 keywords (e.g. period tracker, meal planner, sleep sounds, travel journal, photo enhancer, news digest, coupon finder) to find what users hate about existing mobile software, and what we did was we analyzed these negative reviews to find improvements users can do to make a mobile app competitor.
