# CPU vs RefreshRate

The clearest difference is rating: CPU at 4.7 against RefreshRate's 3.4. CPU also leads on review sentiment (61% vs 41%) and update cadence (fortnightly vs every 5 weeks). RefreshRate's advantage is ads (none vs shown). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. CPU sells 1 one-off in-app purchase and RefreshRate sells 6 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

CPU holds the better App Store score, 4.7 against 3.4. Both are backed by a comparable volume of ratings — 111 and 33 respectively. Written reviews point the same way: 61% of CPU's written reviews are positive against 41% of RefreshRate's.

CPU ships an update fortnightly, RefreshRate every 5 weeks. Both last shipped on October 12, 2026.
