# Retime vs Study Timer

The clearest difference is update cadence: Retime at every 5 days against Study Timer's every 6 weeks. Study Timer's advantage is review sentiment (100% vs 72%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Retime sells 3 in-app purchases, starting at $1.99 per month and Study Timer sells 1 in-app purchase, starting at $9.99 per year. Whichever you choose, the download price is not the number that matters.

Retime ships an update every 5 days, Study Timer every 6 weeks. The most recent releases landed on November 5, 2026 and November 11, 2026 respectively.
