# Loop vs Peptico

The clearest difference is ads: Loop at none against Peptico's shown. Peptico's advantage is update cadence (weekly vs every 2 months) and iOS requirement (16.4 vs 26.5). On price, in-app purchases and device support there is nothing between them.

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

Loop ships an update every 2 months, Peptico weekly. Both last shipped on November 5, 2026.
