Changing frequencies was a pain. The slider was linear instead of logarithmic, making it impractical since the most useful frequencies are crammed together in a small part of the slider. I'm resuming my search for a useful tone generator. **Developer response:** You supposed to use the touch sensirive surface to select the frequency sliding each digit up or down. It really doesn't get any easier. ### 2/5 — Doesn't keep playing in background *2014-10-11* This app is worthless because it stops playing sound when you switch away from it, even with the "Keep Alive" setting enabled in the app. How am I supposed to switch to my RTA app to analyze the results of piping the tones through my PA if this app stops making sound when I switch away from it?!? ### 3/5 — çà bloc un peut des fois *2014-07-07* oui pas mal mais sa bloc ### 2/5 — Ok, but no Bluetooth support *2014-06-07* It works as advertised, but I wanted to use it to test the frequency output of my Bluetooth speakers so I could use that as a guide for my equalizer settings. But the output only goes to the tiny iPhone speaker, not out to the Bluetooth device. ### 3/5 — ちょっと残念 *2013-12-24* オーディオの測定用の基準信号が簡単に得られるのは良い。しかし、矩形波とのこぎり波は歪が多過ぎて使い物にならない。この点の改善を希望する。 ### 4/5 — Need BT connection *2013-07-05* Love this app. More so when equip with A2DP for BlueTooth connection, as an alternative to hard wiring. ### 2/5 — Not usable with apple TV *2013-07-05* The app is good but its not able to play the sound on the apple TV. I purchased the payed version by inapp pay. 5 stars when fixed. ### 2/5 — Too many ads *2013-01-16* If it wasn't because of the constant ads this would be a great app. ### 5/5 — Z *2012-12-02* Malade.. Je men sert pour l'electro stimulation. Pas besoin d' e-stim ou tens a 500$ ### 5/5 — Best free generator *2012-10-05* Great feature set. Everything you need Love the delay sweep ### 5/5 — Superb *2012-08-24, version 1.02* 5 stars + ## Most critical reviews (10 lowest-rated) ### 1/5 — Worthless *2015-05-29* Could not get it to generate ANY sound. Waste of time, and money. Would give negative stars if I could. **Developer response:** Were you using a bluetooth speaker or headset by any chance? It should work perfectly fine using the inbuilt or wired speaker. ### 1/5 — Did not work for me *2014-03-02* I couldnt get any sound to play. ### 1/5 — Buggy, ads make it unusable, no airplay *2013-12-17* The UI is good but the sound ends up distorted, and it stops playing while it pops up ads. ### 1/5 — Ad City! Avoid *2013-06-25, version 1.03* All was going well until the latest update. Then, the dreaded Ad disease kicked in. It was so bad that I am deleting it and moving to a competitor. Counter-intuitive, programmer! One star. ### 1/5 — Junk *2013-03-18* Not worth the time to down load it ### 1/5 — Ads ads ads *2013-03-12* Does what it should, but even after buying it initially, it has very intrusive ads wanting more money. Scam IMHO ### 1/5 — Crippleware *2012-10-29* Constant intrusive ads. There is another free freq gen out there devoid of ads. I'm going back to it. Dev, your intrusive ads made it so I don't want to give you my business. Well done! ### 1/5 — Useless *2012-10-11* Sound stops if you lock your phone. Seriously? Makes it pretty much useless to me. ### 1/5 — not useful *2012-08-28* really bad. ### 1/5 — 오류투성이임 *2012-08-11* 사용자 편의를 위한 인터페이스는 그럭저럭이지만 중요한 동작은 오류투성이임 ## Most praised reviews (10 highest-rated) ### 5/5 — シンプルで使いやすい *2021-05-12* 楽器のチューナーとして使ってます。 ちょこっと使いたいときや、突然〜〜Hzが必要になった時にすぐ使えるので重宝してます。 オクターブで変更できるのも何気に嬉しいです。 ### 5/5 — Everything you could ask for and more. *2016-02-06, version 1.05* This has everything I would need and more for a tone generator. It also has some interesting features I was not expecting but am thinking will be very useful. Very glad I opted for this one. Don't believe apple in app purchases label, the developers have made it all available for the initial purchase price which is amazingly little considering haw much functionality you get. Used to use "Tone Generator Pro" before they wrecked it with a complete overhaul. This APP is way better . ### 5/5 — Très complet *2015-03-12* Application pour générer toutes sortes de signal de test, très complète, fonctionne parfaitement. ### 5/5 — Awesome app *2014-06-29* Very useful for Car audio, Guitar tuning... Has many useful tests ### 5/5 — Sounds good!! *2014-05-28* 개인적으로 음향분야에서 필요한 소스를 잘내어주는 어플. 업데이트도 잘 진행되었기에 평소에는 쓰지않는 리뷰를 작성하게 되었다. 필요한 분들은 좋을듯. ### 5/5 — Real good application *2014-05-27* You can make all fundamental sound such as sine waves, noises, octave and finding note frequency. If it has harmony function, it'll be the best app of tone generator. ### 5/5 — Must have Home Theater tool *2013-10-15* This is the perfect tool for calibrating my home theater! It does need to fix the airplay function. Just not work ### 5/5 — WORKS GREAT *2013-06-26* As a retired Broadcast Engineer, I can use this app along with my iPhone 5 as an audio frequency generator. With the appropriate audio cable plugged into my phone, I can do a freq run into my audio console (mixing board). The app is very handy & convenient! ### 5/5 — Great job *2013-03-31* Just downloaded and had a play with app, hooked phone to oscilloscope and am very happy to say was surprisingly accurate. will use in the field. Does what it says, ### 5/5 — Good *2013-03-13* Good --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
