Verdict
The clearest difference is review sentiment: I at 100% against TDI Tuning's 39%. I also leads on rating (5.0 vs 4.2) and iOS requirement (12.0 vs 15.6). TDI Tuning's advantage is ratings volume (5 vs 1). On price, update cadence, 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, 5.0 against 4.2. That said, the two scores are not equally well evidenced: TDI Tuning has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 39% of TDI Tuning's written reviews are positive against 100% of I's.
TDI Tuning ships an update every 3 months, I every 2 months. The most recent releases landed on October 5, 2026 and October 28, 2026 respectively.
