Verdict
The clearest difference is price: Cheatsheet at Free against USB Disk's $0.99. Cheatsheet also leads on ads (none vs shown) and update cadence (every 2 weeks vs every 2 months). On rating, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Cheatsheet is free to download; USB Disk costs $0.99 up front. USB Disk sells 10 in-app purchases, starting at $4.99 per month and Cheatsheet sells 9 in-app purchases, starting at $0.99 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 — 4.6 for USB Disk against 4.7 for Cheatsheet. That said, the two scores are not equally well evidenced: Cheatsheet has 1.9K ratings behind it against 161, so its average is the more settled of the two. Written reviews are what separate them: 71% of USB Disk's written reviews are positive against 81% of Cheatsheet's.
USB Disk ships an update every 2 months, Cheatsheet every 2 weeks. Both last shipped on November 6, 2026.
