# TDM vs Calyra

The clearest difference is ads: TDM at none against Calyra's shown. TDM also leads on review sentiment (91% vs 59%) and iOS requirement (13.0 vs 15.1). Calyra's advantage is rating (4.7 vs 4.3) and ratings volume (158 vs 9). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. TDM sells 5 one-off in-app purchases and Calyra sells 3 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Calyra holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Calyra has 158 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 91% of TDM's written reviews are positive against 59% of Calyra's, so the app with the better star average is not the one people write more warmly about.

TDM ships an update every 3 weeks, Calyra every 10 days. The most recent releases landed on November 3, 2026 and November 8, 2026 respectively.
