# Tide Graph Pro vs Offline Topo Map

The clearest difference is update cadence: Offline Topo Map at every 5 days against Tide Graph Pro's every 3 weeks. Offline Topo Map also leads on review sentiment (100% vs 84%) and monetization model (free with in-app purchases vs paid). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Tide Graph Pro sells 2 in-app purchases, starting at $1.99 per month and Offline Topo Map sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Tide Graph Pro ships an update every 3 weeks, Offline Topo Map every 5 days. Both last shipped on November 13, 2026.
