Verdict

The call

The clearest difference is rating: Sequence at 4.3 against 3D Scratchpad's 2.7. Sequence also leads on update cadence (every 10 days vs every 15 months) and ratings volume (65 vs 12). 3D Scratchpad's advantage is review sentiment (19% vs 0%). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Sequence holds the better App Store score, 4.3 against 2.7. That said, the two scores are not equally well evidenced: Sequence has 65 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 19% of 3D Scratchpad's written reviews are positive against 0% of Sequence's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

3D Scratchpad ships an update every 15 months, Sequence every 10 days. Both last shipped on September 22, 2026.
