# Rekoe vs SEIMON

The clearest difference is ads: SEIMON at none against Rekoe's shown. Rekoe's advantage is update cadence (every 4 days vs every 3 weeks) and iOS requirement (14.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Rekoe sells 3 one-off in-app purchases and SEIMON sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Rekoe ships an update every 4 days, SEIMON every 3 weeks. The most recent releases landed on October 6, 2026 and October 9, 2026 respectively.
