# Prepd vs Rew

The clearest difference is ads: Prepd at none against Rew's shown. Prepd also leads on iOS requirement (15.0 vs 17.0). Rew's advantage is update cadence (every 3 days vs fortnightly). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Prepd sells 5 in-app purchases, starting at $39.99 per month and Rew sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Prepd ships an update fortnightly, Rew every 3 days. The most recent releases landed on November 9, 2026 and October 31, 2026 respectively.
