ReceptionRating · Positive reviews · Number of ratings

Reward Charts by Stellar holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Reward Charts by Stellar has 714 ratings behind it against 91, so its average is the more settled of the two. Written reviews complicate that: 52% of Reward Charts by Stellar's written reviews are positive against 63% of TallyFlex's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Reward Charts by Stellar ships an update every 2 months, TallyFlex weekly. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
