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.

App works well for the most part. I don't find the data entry part to be overly intuitive, but that is just going to take some time getting used to. Only real issue that I really have is that now that I have the paid version the settings button, and other buttons at the top are pushed behind the phone's status bar (behind the clock, cell status, and such). It is impossible to get to these features where they are currently positioned.

This used to be a go-to app for unit conversion, but something changed. Instead of the unobtrusive banner ads it always had, it now has unskipable full-screen ads that are actually impossible to close. If this is going to be the norm for the app going forward, I cannot and will not recommend using it. Edit: The developer seems to have not bothered to fully read my statement. I had no problem with the banner ads. My problem is the loud, full screen, unskippable, uncloseable ads that are present.
