# Absolute Tides vs Tide Pro

The clearest difference is ads: Absolute Tides at none against Tide Pro's shown. Absolute Tides also leads on review sentiment (67% vs 38%) and device support (4 vs 2). Tide Pro's advantage is update cadence (every 2 months vs every 5 months). On price, in-app purchases, monetization model and iOS requirement there is nothing between them.

Both are free to download. Absolute Tides sells 11 one-off in-app purchases and Tide Pro sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Absolute Tides ships an update every 5 months, Tide Pro every 2 months. The most recent releases landed on August 18, 2026 and September 19, 2026 respectively.
