Verdict

The call

The clearest difference is review sentiment: Untangle at 89% against iPromptU's 50%. Untangle also leads on update cadence (every 4 weeks vs every 8 months) and ratings volume (442 vs 3). iPromptU's advantage is in-app purchases (none vs 2) and rating (5.0 vs 4.6). On price, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

iPromptU holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Untangle has 442 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 50% of iPromptU's written reviews are positive against 89% of Untangle's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

iPromptU ships an update every 8 months, Untangle every 4 weeks. The most recent releases landed on October 23, 2026 and October 29, 2026 respectively.
