Verdict

The call

The clearest difference is review sentiment: FieldFox at 100% against Todo's 48%. FieldFox also leads on in-app purchases (none vs 2). Todo's advantage is rating (4.4 vs 4.0) and ratings volume (396 vs 4). On price, ads, device support and iOS requirement there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Todo sells 2 in-app purchases, starting at $5.99 per month. FieldFox asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Todo holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: Todo has 396 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 100% of FieldFox's written reviews are positive against 48% of Todo's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

FieldFox ships an update every 12 months, Todo every 2 months. The most recent releases landed on October 8, 2026 and October 15, 2026 respectively.
