# Reward Charts by Stellar vs TallyFlex

The clearest difference is update cadence: TallyFlex at weekly against Reward Charts by Stellar's every 2 months. TallyFlex also leads on review sentiment (63% vs 52%) and device support (3 vs 1). Reward Charts by Stellar's advantage is rating (4.6 vs 4.3) and ratings volume (714 vs 91). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Reward Charts by Stellar sells 1 one-off in-app purchase and TallyFlex sells 2 in-app purchases, starting at $27.99 per month. Whichever you choose, the download price is not the number that matters.

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.

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.
