# Amark vs 露出計

The clearest difference is ads: Amark at none against 露出計's shown. Amark also leads on monetization model (free vs ad-supported). 露出計's advantage is update cadence (every 6 weeks vs every 8 months) and iOS requirement (12.4 vs 15.0). On price, in-app purchases and device support there is nothing between them.

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

Amark ships an update every 8 months, 露出計 every 6 weeks. The most recent releases landed on October 3, 2026 and October 11, 2026 respectively.
