# FITTHEOREM vs Impact Activities TX

The clearest difference is rating: FITTHEOREM at 3.7 against Impact Activities TX's 1.3. FITTHEOREM also leads on update cadence (every 2 weeks vs every 6 months) and iOS requirement (12.0 vs 15.1). Impact Activities TX's advantage is in-app purchases (none vs 3) and ratings volume (91 vs 17). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. FITTHEOREM sells 3 in-app purchases, starting at $11.99 per month. Impact Activities TX asks for nothing beyond the download.

FITTHEOREM holds the better App Store score, 3.7 against 1.3. That said, the two scores are not equally well evidenced: Impact Activities TX has 91 ratings behind it against 17, so its average is the more settled of the two. Written reviews complicate that: 0% of FITTHEOREM's written reviews are positive against 4% of Impact Activities TX's, so the app with the better star average is not the one people write more warmly about.

FITTHEOREM ships an update every 2 weeks, Impact Activities TX every 6 months. The most recent releases landed on October 10, 2026 and October 17, 2026 respectively.
