# USB Disk vs Sketch Simply

The clearest difference is rating: USB Disk at 4.6 against Sketch Simply's 3.6. USB Disk also leads on review sentiment (71% vs 50%) and ratings volume (161 vs 5). Sketch Simply's advantage is ads (none vs shown) and update cadence (every 11 days vs every 2 months). On price, in-app purchases, monetization model and device support there is nothing between them.

USB Disk costs $0.99 and Sketch Simply $0.99 up front. USB Disk sells 10 in-app purchases, starting at $4.99 per month and Sketch Simply sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

USB Disk holds the better App Store score, 4.6 against 3.6. That said, the two scores are not equally well evidenced: USB Disk has 161 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 71% of USB Disk's written reviews are positive against 50% of Sketch Simply's.

USB Disk ships an update every 2 months, Sketch Simply every 11 days. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
