# Stackr vs PepShot

The clearest difference is rating: PepShot at 5.0 against Stackr's 4.4. PepShot also leads on review sentiment (100% vs 67%). Stackr's advantage is monetization model (freemium vs subscription) and ratings volume (174 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Stackr sells 7 in-app purchases, starting at $7.99 per 7 days and PepShot sells 2 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

PepShot holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Stackr has 174 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 67% of Stackr's written reviews are positive against 100% of PepShot's.

Stackr ships an update every 4 days, PepShot every 5 days. The most recent releases landed on October 18, 2026 and October 5, 2026 respectively.
