# Caltopia vs TreadSimple

The clearest difference is monetization model: TreadSimple at freemium against Caltopia's paid. TreadSimple also leads on update cadence (every 2 days vs every 3 days) and iOS requirement (15.0 vs 17.0). Caltopia's advantage is ratings volume (7 vs 1). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Caltopia sells 1 one-off in-app purchase and TreadSimple sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Caltopia against 5.0 for TreadSimple. That said, the two scores are not equally well evidenced: Caltopia has 7 ratings behind it against 1, so its average is the more settled of the two.

Caltopia ships an update every 3 days, TreadSimple every 2 days. The most recent releases landed on October 8, 2026 and October 10, 2026 respectively.
