Ratings and reviews

Enshittification just claimed another one. I bought a lifetime of premium and this new update is basically just to push their new monthly subscription that adds "themes" and hides features like favorites and quick access behind a monthly paywall when I'm pretty sure they were included in the "premium" version I've already bought. The previous version of this app was perfect for what it was, a tool let you easily convert units without asking AI.

This was a great app until the new update. Now, the ads make the app unusable for the conversions I need. Unless I can uninstall the update and go back to when it was useful, this app is no longer relevant... I only need a weight conversion, so it's not worth paying the subscription to get rid of the ads.

When I installed this app a few years ago, it delivered exactly as promised quickly. Now when I use it, I must wait for a brief ad to load. And there's more ads in between conversions. At this point, it's faster and less annoying to pull up Google every time I want to convert some measurements.
