# Time Atlas vs GemBook

The clearest difference is ads: Time Atlas at none against GemBook's shown. Time Atlas also leads on update cadence (every 6 days vs every 3 weeks) and ratings volume (75 vs 5). GemBook's advantage is review sentiment (100% vs 77%) and rating (5.0 vs 4.7). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Time Atlas sells 3 in-app purchases, starting at $8.99 per month and GemBook sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

GemBook holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Time Atlas has 75 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 77% of Time Atlas's written reviews are positive against 100% of GemBook's.

Time Atlas ships an update every 6 days, GemBook every 3 weeks. The most recent releases landed on October 30, 2026 and October 7, 2026 respectively.
