Verdict

The call

The clearest difference is review sentiment: Stack Overflow AR at 100% against Tayasui Doodle Book's 47%. Stack Overflow AR also leads on in-app purchases (none vs 10) and ads (none vs shown). Tayasui Doodle Book's advantage is rating (4.5 vs 4.0) and update cadence (fortnightly vs every 3 months). On price, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Tayasui Doodle Book holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Tayasui Doodle Book has 126 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 47% of Tayasui Doodle Book's written reviews are positive against 100% of Stack Overflow AR's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Tayasui Doodle Book ships an update fortnightly, Stack Overflow AR every 3 months. The most recent releases landed on November 6, 2026 and November 2, 2026 respectively.
