# Sei vs Heave

The clearest difference is ads: Sei at none against Heave's shown. Sei also leads on iOS requirement (15.1 vs 26.2). Heave's advantage is update cadence (every 4 days vs fortnightly). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Sei sells 2 in-app purchases, starting at $5.99 per month and Heave sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Sei ships an update fortnightly, Heave every 4 days. The most recent releases landed on October 28, 2026 and October 24, 2026 respectively.
