# ASTRO vs ONE

The clearest difference is in-app purchases: ONE at none against ASTRO's 1. ONE also leads on ads (none vs shown) and iOS requirement (15.0 vs 18.0). ASTRO's advantage is update cadence (every 4 days vs monthly). On price and device support there is nothing between them.

Both are free to download. ASTRO sells 1 one-off in-app purchase. ONE asks for nothing beyond the download.

ASTRO ships an update every 4 days, ONE monthly. The most recent releases landed on September 29, 2026 and September 15, 2026 respectively.
