Verdict

The call

One Day At A Time and AA Big Book both sit at 4.3 stars, but that hides the real split: 46% of One Day At A Time's written reviews are positive against 0% of AA Big Book's. One Day At A Time also leads on in-app purchases (none vs 3) and ads (none vs shown). AA Big Book's advantage is update cadence (every 8 days vs every 2 weeks) and ratings volume (34 vs 6). On price, rating and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

AA Big Book holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: AA Big Book has 34 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 46% of One Day At A Time's written reviews are positive against 0% of AA Big Book's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

One Day At A Time ships an update every 2 weeks, AA Big Book every 8 days. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
