Verdict
The clearest difference is review sentiment: oneOBI at 100% against My Tello's 46%. oneOBI also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). My Tello's advantage is rating (4.3 vs 3.0) and ratings volume (1.9K vs 2). On price, update cadence, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
My Tello holds the better App Store score, 4.3 against 3.0. That said, the two scores are not equally well evidenced: My Tello has 1.9K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 46% of My Tello's written reviews are positive against 100% of oneOBI's, so the app with the better star average is not the one people write more warmly about.
My Tello ships an update every 3 weeks, oneOBI fortnightly. The most recent releases landed on October 26, 2026 and October 23, 2026 respectively.
