## Most critical reviews (2 lowest-rated)

### 1/5 — Ads make this terrible.

*2025-05-23*

Unable to skip ads, unable to pay to remove them. Watch the ad and the app doesn’t let me progress. Terrible.

### 5/5 — Easy, clear and worth it!

*2026-06-07*

This calculator made sorting through my pokemon so easy. I usually just deal with ads to avoid paying any money, but I was excited to see an ad free subscription option pop up. Definitely worth it to support this one, especially being reasonably priced. My only issue is that the screen cuts off part of the total berry energy amount on my iPhone. It only shows the first few numbers. It’s not an issue on my iPad, but I primarily use my phone.
