# BiteFit Pro vs Stackr

The clearest difference is rating: BiteFit Pro at 5.0 against Stackr's 4.4. BiteFit Pro also leads on review sentiment (100% vs 68%) and iOS requirement (15.1 vs 17.0). Stackr's advantage is ratings volume (202 vs 2) and update cadence (weekly vs every 3 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. BiteFit Pro sells 2 in-app purchases, starting at $4.99 per month and Stackr sells 7 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

BiteFit Pro holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Stackr has 202 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 100% of BiteFit Pro's written reviews are positive against 68% of Stackr's.

BiteFit Pro ships an update every 3 weeks, Stackr weekly. The most recent releases landed on October 31, 2026 and November 2, 2026 respectively.
