Portion Track also leads on update cadence (every 3 days vs every 3 weeks). 21 Day Container Tracker's advantage is rating (4.7 vs 4.3) and ratings volume (510 vs 6). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. 21 Day Container Tracker sells 3 in-app purchases, starting at $4.99 per 7 days and Portion Track sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

21 Day Container Tracker holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: 21 Day Container Tracker has 510 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 74% of 21 Day Container Tracker's written reviews are positive against 80% of Portion Track's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

21 Day Container Tracker ships an update every 3 weeks, Portion Track every 3 days. The most recent releases landed on October 15, 2026 and October 5, 2026 respectively.
