# Memory vs PRO CHARTS

Memory and PRO CHARTS both sit at 4.5 stars, but that hides the real split: 64% of Memory's written reviews are positive against 17% of PRO CHARTS's. Memory also leads on iOS requirement (11.4 vs 15.6). PRO CHARTS's advantage is ratings volume (8.5K vs 52) and chart position (#103 vs unranked). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Memory sells 16 one-off in-app purchases and PRO CHARTS sells 4 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.5 for Memory against 4.5 for PRO CHARTS. That said, the two scores are not equally well evidenced: PRO CHARTS has 8.5K ratings behind it against 52, so its average is the more settled of the two. Written reviews are what separate them: 64% of Memory's written reviews are positive against 17% of PRO CHARTS's.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 7, 2026 and October 15, 2026 respectively.
