# SEQ vs Mono

The clearest difference is price: Mono at Free against SEQ's $1.99. Mono also leads on in-app purchases (none vs 1) and update cadence (every 4 days vs every 6 weeks). SEQ's advantage is ads (none vs shown) and ratings volume (2.6K vs 1). On device support there is nothing between them.

Mono is free to download; SEQ costs $1.99 up front. SEQ sells 1 one-off in-app purchase. Mono asks for nothing beyond the download.

Mono holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: SEQ has 2.6K ratings behind it against 1, so its average is the more settled of the two.

SEQ ships an update every 6 weeks, Mono every 4 days. The most recent releases landed on November 13, 2026 and November 4, 2026 respectively.
