Verdict
The clearest difference is ads: UniTuner at none against Tuner+'s shown. UniTuner also leads on update cadence (every 6 weeks vs every 6 months) and review sentiment (94% vs 82%). Tuner+'s advantage is ratings volume (1.1K vs 127) and iOS requirement (13.0 vs 15.6). On price, rating, in-app purchases and monetization model 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. Tuner+ sells 1 one-off in-app purchase and UniTuner sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.7 for Tuner+ against 4.6 for UniTuner. That said, the two scores are not equally well evidenced: Tuner+ has 1.1K ratings behind it against 127, so its average is the more settled of the two. Written reviews are what separate them: 82% of Tuner+'s written reviews are positive against 94% of UniTuner's.
Tuner+ ships an update every 6 months, UniTuner every 6 weeks. The most recent releases landed on October 16, 2026 and October 14, 2026 respectively.
