# Stacksy vs PeptideMax

The clearest difference is monetization model: PeptideMax at free with in-app purchases against Stacksy's subscription. Stacksy's advantage is ads (none vs shown) and update cadence (every 2 days vs every 8 days). On price, ratings volume, in-app purchases and device support there is nothing between them.

Both are free to download. Stacksy sells 5 in-app purchases, starting at $9.99 per month and PeptideMax sells 3 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Stacksy holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 16 and 14 respectively.

Stacksy ships an update every 2 days, PeptideMax every 8 days. The most recent releases landed on October 11, 2026 and October 6, 2026 respectively.
