# Prove It vs Buy'r

The clearest difference is review sentiment: Buy'r at 85% against Prove It's 9%. Buy'r also leads on ads (none vs shown) and rating (4.8 vs 4.4). Prove It's advantage is ratings volume (16K vs 601) and update cadence (every 6 days vs fortnightly). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Prove It sells 25 in-app purchases, starting at $4.99 per 7 days and Buy'r sells 2 in-app purchases, starting at $5.00 per month. Whichever you choose, the download price is not the number that matters.

Buy'r holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Prove It has 16K ratings behind it against 601, so its average is the more settled of the two. Written reviews point the same way: 9% of Prove It's written reviews are positive against 85% of Buy'r's.

Prove It ships an update every 6 days, Buy'r fortnightly. The most recent releases landed on October 26, 2026 and October 22, 2026 respectively.
