# Impact vs Growfitter

The clearest difference is in-app purchases: Growfitter at none against Impact's 3. Growfitter also leads on review sentiment (79% vs 58%). Impact's advantage is ads (none vs shown) and rating (4.3 vs 3.9). On price, monetization model, device support and iOS requirement there is nothing between them.

Both are free to download. Impact sells 3 in-app purchases, starting at $0.99 per month. Growfitter asks for nothing beyond the download.

Impact holds the better App Store score, 4.3 against 3.9. That said, the two scores are not equally well evidenced: Impact has 367 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 58% of Impact's written reviews are positive against 79% of Growfitter's, so the app with the better star average is not the one people write more warmly about.

Impact ships an update every 9 days, Growfitter every 3 weeks. The most recent releases landed on November 6, 2026 and November 2, 2026 respectively.
