# Atlas Docs vs OneClick Code

The clearest difference is rating: OneClick Code at 4.8 against Atlas Docs's 4.2. OneClick Code also leads on update cadence (fortnightly vs every 14 months) and ratings volume (182 vs 5). Atlas Docs's advantage is in-app purchases (none vs 10) and review sentiment (100% vs 83%). On price, ads and device support there is nothing between them.

Both are free to download. OneClick Code sells 10 in-app purchases, starting at $31.99 per month. Atlas Docs asks for nothing beyond the download.

OneClick Code holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: OneClick Code has 182 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 100% of Atlas Docs's written reviews are positive against 83% of OneClick Code's, so the app with the better star average is not the one people write more warmly about.

Atlas Docs ships an update every 14 months, OneClick Code fortnightly. The most recent releases landed on September 8, 2026 and September 24, 2026 respectively.
