Also, I want this to continue to play the tone(s) even if my phone goes into sleep mode. ### 5/5 — Great *2012-06-20* Great little app, does what it says it does. ### 4/5 — Pretty darn good *2012-03-29* Square wave is a bit dirty on scope. And I would love to have a +/- 100 option. Getting to 1khz takes forever ### 5/5 — Great app! *2012-03-25* It's the only tone generator app that I found that does what I needed to do. It's really simple and it works great. ### 4/5 — Worth it *2012-03-14* Very simple and easy to use. All I can suggest to the developer is to include a sawtooth generator and a way to rapidly enter a custom frequency for a given generator. ### 5/5 — Gostei. *2012-02-20* Muito chic.Da uma boa idéia sobre o assunto. ### 5/5 — Review *2012-02-17, version 1.0* Does what it advertises, no complaints ### 4/5 — Very fine *2012-02-07* Great interface, great concept and great price. I would love to see the ability to save multiple sets, save up to 24 pitches per set ( not necessarily all playable simultaneously), and the ability to set the pitch as a ratio of the starting pitch. I.e D as 9/8 of the pitch of C). As it is this can be a great help to learning just intonation. ### 5/5 — Total control *2012-02-03* It's the only app out there that will allow you to make as many single frequency queues as you want. Its all very simple and easy to use. I would suggest as a feature or addition, to have a direct input box for the frequency entry instead of clicking on the "+" and "-" sign. And, how about a timer for each of the frequency queue. How about an iPad version! Lol, at this point you might as well call it "Tone Generator Pro". Hey, don't take it the wrong way, I like the app as it is already. ## Most critical reviews (10 lowest-rated) ### 1/5 — Did not work with my phone *2018-08-01* As I go up the scale, tones are all over the place. Tried through the phone speaker and Bluetooth with the same result ### 1/5 — Good app but... *2013-02-13, version 1.0* This is a great app, but the sound tones turn off when my phone hibernates which makes this app useless, please update this app so that the app stays active when the phone sleeps, I'll give this app 5 stars if that change is made ### 1/5 — One major flaw *2012-03-27, version 1.0* I want the tone to continue when the phone turns off but the tone stops so the app is kind of useless for my purposes. ### 3/5 — Nice, but needs slight adjusting *2016-06-21* I love saving tones, but I'd also love to label them. Give themselves name. I'd also love for the tone to keep generating once the phone screen goes black so we can have a tone for a extended time. Thankyou! I have more ideas if you'd like to hear them, email me ### 3/5 — Nbl *2011-11-26* Pour tout preneur de son. Bien faite ### 4/5 — Exactly what I was looking for... *2016-10-28* I'm an experimental musician that was looking for a small tone generator in which to produce pure sine waves with adjustable frequencies. I also needed a unit that could play more than one wave at a time. This app did the trick (and you can't beat the 99 cent price). The only downfall is that there are other apps that allow much higher highs and much lower subs (none that I've found that can play multiple tones simultaneously, however). Definitely worth the money. ### 4/5 — Very useful! *2015-10-30* I use this app as a healing facilitator - both as a tinnitus reducer & to generate revitalizing Solfeggio tones. Very easy to use. ### 4/5 — Easy to use... *2013-12-25, version 1.0* Simple and straight forward App. ### 4/5 — App does what it was made for *2013-11-09* It just works. Ain't fancy but a nice introduction to audio. ### 4/5 — Very good app but... *2013-06-11* If you could update it so that you could have continuous play while other apps are playing as well. That would Change the app to 5 stars for me ## Most praised reviews (10 highest-rated) ### 5/5 — D *2026-02-17* Good app ### 5/5 — 使いやすくてとても気に入ってます *2023-02-13* iPhoneスリープ状態だと音出ないのでそこだけ残念ですが、他は完璧です。 ### 5/5 — Tunes anything *2019-08-31* I can tune my violin and I can tone my violin plates in helping me make better violins. ### 5/5 — Presets *2018-11-04* I tried a number of other apps but for my use of testing audio band pass filters the ability to present several frequencies is a winner. ### 5/5 — Great for relaxation and studying *2018-04-04, version 1.1* I use this app to play tones to drown out distracting sounds while I study. I would love for this app to be able to continue playing when the iPhone is locked or while using other apps, but it’s not a big deal that it doesn’t. My personal favorite “recipe” right now is 44.5Hz, 44.6Hz, 88.6Hz, 177.2Hz, and 223.3Hz all on together. Very relaxing! ### 5/5 — Does everything I could want *2015-06-17* Apparently there's a very small consumer base for wave generator apps, so I won't nitpick here. For all of your sine, saw, and triable wave needs, this app has you covered. ### 5/5 — Great app *2013-12-12* I used it to adjust frequency response of my home heather room's subwoofer. Went in steps from 20 to 200hz and used a sound pressure level meter. Great and easy to use. ### 5/5 — Good App *2013-10-29* Works as advertised. ### 5/5 — Love it. *2013-08-26, version 1.0* This is a wonderfully fun app. Good for the mind. ### 5/5 — Fantastic! *2013-07-24, version 1.0* Its simple, has what is needed, adjustable, valuable tool!
