# Hemi vs SeptaSync

The clearest difference is monetization model: SeptaSync at freemium against Hemi's subscription. SeptaSync also leads on review sentiment (67% vs 32%). Hemi's advantage is rating (4.4 vs 4.0) and ratings volume (2.5K vs 4). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Hemi sells 2 in-app purchases, starting at $14.99 per month and SeptaSync sells 6 in-app purchases, starting at $10.00 per month. Whichever you choose, the download price is not the number that matters.

Hemi holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: Hemi has 2.5K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 32% of Hemi's written reviews are positive against 67% of SeptaSync's, so the app with the better star average is not the one people write more warmly about.

Hemi ships an update every 2 weeks, SeptaSync every 3 weeks. The most recent releases landed on September 25, 2026 and September 18, 2026 respectively.
