# Reader++ vs Space Atlas

The clearest difference is update cadence: Space Atlas at every 2 days against Reader++'s fortnightly. Space Atlas also leads on iOS requirement (15.1 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Reader++ sells 4 in-app purchases, starting at $4.99 per month and Space Atlas sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Reader++ ships an update fortnightly, Space Atlas every 2 days. Both last shipped on October 31, 2026.
