# ContarinApp vs API

The clearest difference is in-app purchases: ContarinApp at none against API's 10. ContarinApp also leads on iOS requirement (13.0 vs 15.5). API's advantage is update cadence (monthly vs every 4 months). On price, ads and device support there is nothing between them.

Both are free to download. API sells 10 in-app purchases, starting at $35.00 per month. ContarinApp asks for nothing beyond the download.

ContarinApp ships an update every 4 months, API monthly. The most recent releases landed on October 10, 2026 and October 16, 2026 respectively.
