Verdict
The clearest difference is rating: i at 2.6 against BT's 1.0. i also leads on ratings volume (96 vs 5) and update cadence (monthly vs every 3 months). On price, review sentiment, ads and in-app purchases 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.
i holds the better App Store score, 2.6 against 1.0. That said, the two scores are not equally well evidenced: i has 96 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 20% of BT's written reviews are positive against 15% of i's, so the app with the better star average is not the one people write more warmly about.
BT ships an update every 3 months, i monthly. The most recent releases landed on October 3, 2026 and October 24, 2026 respectively.
