Verdict
The clearest difference is rating: TAC Mobile at 4.5 against ESRT+'s 3.7. TAC Mobile also leads on iOS requirement (10.0 vs 13.0). ESRT+'s advantage is review sentiment (17% vs 0%) and ratings volume (28 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
TAC Mobile holds the better App Store score, 4.5 against 3.7. That said, the two scores are not equally well evidenced: ESRT+ has 28 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 0% of TAC Mobile's written reviews are positive against 17% of ESRT+'s, so the app with the better star average is not the one people write more warmly about.
TAC Mobile ships an update monthly, ESRT+ fortnightly. The most recent releases landed on September 17, 2026 and September 10, 2026 respectively.
