# TodoMaps vs Deer

The clearest difference is rating: Deer at 4.8 against TodoMaps's 4.6. Deer also leads on update cadence (every 9 days vs monthly). TodoMaps's advantage is ratings volume (54 vs 6) and iOS requirement (13.0 vs 15). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. TodoMaps sells 1 one-off in-app purchase and Deer sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Deer holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: TodoMaps has 54 ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 82% of TodoMaps's written reviews are positive against 89% of Deer's.

TodoMaps ships an update monthly, Deer every 9 days. The most recent releases landed on September 24, 2026 and September 22, 2026 respectively.
