Verdict
The clearest difference is monetization model: Time Atlas at free against Sonaur's free with in-app purchases. Time Atlas also leads on ratings volume (58 vs 10). Sonaur's advantage is review sentiment (100% vs 76%) and rating (5.0 vs 4.8). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Time Atlas sells 3 in-app purchases, starting at $8.99 per month and Sonaur sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Sonaur holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Time Atlas has 58 ratings behind it against 10, so its average is the more settled of the two. Written reviews point the same way: 76% of Time Atlas's written reviews are positive against 100% of Sonaur's.
Time Atlas ships an update every 5 days, Sonaur every 9 days. The most recent releases landed on October 13, 2026 and October 3, 2026 respectively.
