# Lab | Audio vs Helio Sequencer

The clearest difference is rating: Helio Sequencer at 4.4 against Lab | Audio's 4.0. Helio Sequencer also leads on ratings volume (13 vs 1) and iOS requirement (11.0 vs 27.0). Lab | Audio's advantage is update cadence (every 3 weeks vs every 3 months) and review sentiment (100% vs 86%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Helio Sequencer holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: Helio Sequencer has 13 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Lab | Audio's written reviews are positive against 86% of Helio Sequencer's, so the app with the better star average is not the one people write more warmly about.

Lab | Audio ships an update every 3 weeks, Helio Sequencer every 3 months. Both last shipped on October 24, 2026.
