What Musicians Say: "I play steel guitar with 3 necks. This is my absolute favorite tuner available. Easy to use. Nothing silly, it just works and is super accurate. I retired my old tuner after I got this app. I've tried many other tuner apps and this is the best." - B Sheeley, steel guitar player "Finally a tuner that doesn't suck! A modern interface. Precise. It just opens the tuner directly without any ads." - Leonardo M "This tuner is certainly the best one you can get on the market. I've tried quite a few, this is my go-to, I couldn't get along without it." - Bruce C. "I am pro piano tuner and had many tuner softwares. This is so far the most clean and neat interface I have ever seen. Some software cost almost one thousand dollars but ugly old interface." - Tony Z, Pro Piano Tuner "I've been playing guitar since I was eight. I am now 69. I love this tuner." - Gazorbo We Value Your Opinion Your feedback and reviews are crucial to making StroboPro one of the best tuning apps for musicians on iOS. Privacy: We don't collect your data.

Verdict
The clearest difference is update cadence: Precise Strobe Tuner at every 10 days against UniTuner's every 6 weeks. Precise Strobe Tuner also leads on rating (4.8 vs 4.6). On price, review sentiment, ratings volume and ads 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. UniTuner sells 5 one-off in-app purchases and Precise Strobe Tuner sells 6 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
Precise Strobe Tuner holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 127 and 90 respectively. Written reviews complicate that: 94% of UniTuner's written reviews are positive against 89% of Precise Strobe Tuner's, so the app with the better star average is not the one people write more warmly about.
UniTuner ships an update every 6 weeks, Precise Strobe Tuner every 10 days. Both last shipped on October 18, 2026.
