Verdict
The clearest difference is review sentiment: UltraBoard at 80% against ToDoMemo's 0%. UltraBoard also leads on update cadence (every 2 days vs every 5 months) and ratings volume (190 vs 1). ToDoMemo's advantage is in-app purchases (none vs 1) and rating (5.0 vs 4.5). On price, ads, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. UltraBoard sells 1 in-app purchase, starting at $8.99 per month. ToDoMemo asks for nothing beyond the download.
ToDoMemo holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: UltraBoard has 190 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of ToDoMemo's written reviews are positive against 80% of UltraBoard's, so the app with the better star average is not the one people write more warmly about.
ToDoMemo ships an update every 5 months, UltraBoard every 2 days. The most recent releases landed on October 8, 2026 and October 29, 2026 respectively.
