I love and use it so much. Every month without doubt Apple Music takes from me in my opinion too much, you wanting $4.99 and I’m giving you that, you’re not taking it. In my opinion and I am no exception, if you’re using this app for over a month and not dropping the 4.99 for the paid version….frugal, that’s your new nickname😜download you will not regret it!! ### 5/5 — Best bass tuner for iPhone 15 *2024-03-15* ****I imagine any iPhone.*****To the creator of the app, thank you, for making quick tuning app(from minor adjustments to full scale retune) and allowing us to enjoy it for free.

There is a free version but the $5 is well worth it compared to what you might be paying for a tuner you could lose. Have to get close if I’m not plugged in but it always works. ### 5/5 — Best tuner *2023-08-26, version 3.13.1* This tuner is magnificent and will not only tune a bass guitar but also guitar and other instruments. Held off for a long time on purchase as I already bought T1 but the bass version I think is even better. ### 5/5 — Love this app *2023-07-24* Tuner on my phone is as good as the fancy crap the Guitarists in my band have. There is a free version but the $5 is worth it compared to what you might be paying. Only difference is the free one has ads so you can even get away with just that one if you don’t wanna fork over the money. ### 5/5 — Great stuff *2023-07-08, version 3.13.1* Perfect tuner since it allows basically any custom tuning. No payments needed. I bought the pro version just to support the developer for making such a great app ### 5/5 — Awesome *2023-05-17, version 3.13.1* This is a great tuner. Works super well. I had the free one for a long time. Even that, the ads aren’t overwhelming. Paid is a one time fee and pretty cheap. I use it all the time. Love it. ### 5/5 — The pinnacle of tuning apps *2023-04-24, version 3.13.1* This app is the pinnacle of tuner apps due to how the UI shows the pitch over time in a two dimensional plot, which makes it very easy to see how much your instrument’s tuning is off. And don’t let the name fool you — this works brilliantly for guitar as well. ### 5/5 — The Real Deal *2022-12-14, version 3.13.1* At last, a proper bass tuner. This is invaluable for checking your intonation on fretless or upright bass. ### 5/5 — My favourite tuner *2022-06-19, version 3.13.1* Great app, easy to use. My best tuner for 5 string ### 5/5 — Locks into the note like no other *2022-04-21, version 3.13.1* I’ve tried quite a few tuner apps and was never satisfied until I found this one. It is wonderful for the bass guitar. Many tuners can’t lock into the low E’s vibrations. This does. It is also much more solid for guitar. Love it. Thank you! ### 5/5 — The best tuner for iPhone *2022-03-14, version 3.13.1* Easy to use, fast and accurate. Adjustable A reference and recognizing the octave range a big plus. ## Most critical reviews (10 lowest-rated) ### 2/5 — Basic great, but start with Pro. *2026-08-06, version 3.16* Great app!—have recommended it to several friends…Ads, as usual, are obnoxious ### 2/5 — Wanted to love it *2025-03-01, version 3.16* As a bassist, the premise is great. I should have played with the free version first, but that’s on me. A,D,G tune just fine, but on a 4 string Yamaha with absolutely nothing special about it, the app tunes the E WAY out of tune. I tried changing settings and simply trying it over and over again. I just couldn’t get it to tune my E, and I wasn’t about to test it with my 5 string. ¯\_(ツ)_/¯ ### 4/5 — Pitch is accurate *2025-03-24, version 3.16* both the drone and tuner functions show accurate pitch. I like the way the tuner shows the pitch with the background changing colors. The only drawback is that the orientation is fixed so when I rotate the iPhone the display is upside down ### 4/5 — Worked great *2024-09-17, version 3.13.1* Issues with scratchy sound since ios18 update ### 4/5 — Topp! *2023-12-31* Gibt es nichts zu meckern. ### 4/5 — Useful *2022-10-30* I use this app for tuning my double bass. It has nearly all features i need. For a better tuning of my intonation it would be awesome to have a endless sustain of the „tuning notes“ so i can rehearse to a drone. ### 4/5 — Pitch is accurate *2021-12-22* both the drone and tuner functions show accurate pitch. I like the way the tuner shows the pitch with the background changing colors. The only drawback is that the orientation is fixed so when I rotate the iPhone the display is upside down ### 4/5 — 最低音2个音测不出来 *2021-11-28* 我6s下的同样的这个app就可以测出来 xr就测不出来了 不知道是什么原因 ### 5/5 — Reliable *2026-04-15, version 3.16* Been using this tuner for years. Works great. ### 5/5 — Basic great, but start with Pro. *2026-04-05* Great app!—have recommended it to several friends…Ads, as usual, are obnoxious ## Most praised reviews (8 highest-rated) ### 5/5 — Freakin amazing tuner *2026-02-25, version 3.16* By far the easiest to use for the most accuracy. The UX idea of the waveform is fantastic. I use it while repairing basses. ### 5/5 — The Best *2026-01-03, version 3.16* Perfect tuning for Bass, Ukulele, Guitar and Banjo. Maybe not for Piano. Best to hire a piano tuner. Best tuner app out there. Highly recommend for True Tone. ### 5/5 — Better than Boss and Shure! *2025-06-08, version 3.16* Better than my boss tu3 and my Shure GLXD16+ Digital Wireless Guitar Pedal System. Both professional standard units. The wave signal is easy to see and quickly adjust my tuning. I am meticulous about intonation. I only play 5 n 6 fretless basses. The apps recognition of the E and B string is instant, clear and simple to tune to. Most tuners i’ve used the tuning of the E and B are a bit dodgy. If this format of tuning was available in a stomp pedal i’d buy it. Buy it immediately. Credit where credit is due. This app is brilliant. Needs a trial as part of the purchase though. I chanced the purchase. $9? ABSOLUTELY WORTH IT! Also they don’t take your info. ### 5/5 — Funktioniert *2025-03-24* Erfasst meine HEAD Stimmung ohne Probleme, kein Nonsense, prima. ### 5/5 — BassLOVE *2025-02-22, version 3.16* 5 String Bass Player. (Low B) Fretless….. Love the Fast and Accuracy display… Acoustic & Electric! I got the (Pro) upgrade for $4.99… What a deal! 😉😎 ### 5/5 — Optimal *2025-01-11* genaue und schnelle Stimmung ### 5/5 — BT1 smokes ‘em all *2024-10-16* I’ve tríen ‘em all and BT 1 is The easiest, fastest, friendliest most versatile tuner bar none we at Clevinger Bass junked our professional lab and tech bench tuners and frequency counters in favor of BT1 ! ### 5/5 — Best I’ve found *2024-10-13, version 3.15* And it works well with a five string, too. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
