# flex vs T ID

The clearest difference is rating: flex at 3.4 against T ID's 1.0. flex also leads on update cadence (every 3 days vs every 2 months) and ratings volume (18 vs 4). T ID's advantage is review sentiment (57% vs 29%) and monetization model (free vs freemium). On price, ads, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

flex holds the better App Store score, 3.4 against 1.0. Both are backed by a comparable volume of ratings — 18 and 4 respectively. Written reviews complicate that: 29% of flex's written reviews are positive against 57% of T ID's, so the app with the better star average is not the one people write more warmly about.

flex ships an update every 3 days, T ID every 2 months. The most recent releases landed on October 16, 2026 and October 15, 2026 respectively.
