Verdict
The clearest difference is rating: Tessie at 4.8 against TDAS mobile's 3.7. Tessie also leads on update cadence (weekly vs every 2 months) and ratings volume (9.7K vs 3). TDAS mobile's advantage is review sentiment (100% vs 64%) and in-app purchases (none vs 10). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Tessie sells 10 in-app purchases, starting at $3.99 per month. TDAS mobile asks for nothing beyond the download.
Tessie holds the better App Store score, 4.8 against 3.7. That said, the two scores are not equally well evidenced: Tessie has 9.7K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 64% of Tessie's written reviews are positive against 100% of TDAS mobile's, so the app with the better star average is not the one people write more warmly about.
Tessie ships an update weekly, TDAS mobile every 2 months. The most recent releases landed on November 10, 2026 and November 4, 2026 respectively.
