Sollte die App einst AUv3 Standard bekommen findet sie bestimmt großes Interesse nicht nur bei Physikern😙 ### 5/5 — Worth the money 110% *2026-04-20* Ive been using this a lot for probably over 6 years plus and its the best! I usually dont give random 5 stars to apps but this one is worth it and i just felt the maker of this deserves it. Worth every penny. Thank you so much maker of this app lol! **Developer response:** many thanks! ### 3/5 — $45 AUD not $14 !!!! *2025-08-09* App seems good by the price is a lie **Developer response:** Hello! I checked the Australian App store and the App is priced $14.99 AUD. Not sure where you have the $45 from. Price per region is automatically set by Apple using the set base country (USD 9.99). Please send me a DM to tom@ee-toolkit.com. I am curious why you are seeing $45 AUD. thank you. ### 5/5 — Simple & efficient *2025-05-21* Straightforward tone generator app, 4 wave type options, can adjust freq’s to decimal point precision, max 16 rows per set, can play any combination of rows from 1 at a time to all simultaneously. Can save multiple sets. This app works great for my tone generator application needs. ### 5/5 — Well designed and Highly functional app *2025-03-23* (Pro User) I use this app for background ‘noise’ and to generate binaural beats. It is very easy to generate binaural beats and listen while studying or focusing on major tasks. I often will overlay the ‘noise’ or ‘beats’ while listening to music to better focus. One simple add that would be very nice on an already excellent product is the ability to create Isochronic tones. Also, I would add the keyword tags for MultiTone that it can ‘generate binaural beats’. There is a growing community that uses binaural beats and this app can certainly generate them. ### 5/5 — Buy the bundle! *2025-02-26* Well worth every single penny. ### 5/5 — Flexible…Indeed *2023-09-10* A very flexible app ### 5/5 — Great Tone Generator *2022-04-13* This is a great tone generator. You can mix multiple frequencies together my, save in groups and more!!! ### 3/5 — 21000 max frequency *2021-12-27* Garbage, does not do more than 21000. So mad i wasted my money **Developer response:** I guess I have to explain something ... - this is an Audio App - humans don't hear anything higher than 20kHz - iOS devices cut off at 20kHz for the above reason So, ... no reason to be mad. That's what your device can do. Not more. ### 5/5 — Very awesome & useful *2020-03-03* This is a very awesome and useful app. I’ve been using this for audio filtering and cognitive dissonance purposes. Works awesome with “Audiobus” mixer. What would make the app better is if the user could adjust the phase for each wave such as 45 and 360 degrees as audio and AC operate both on the electromagnetic radiation spectrum. What would also help would be to add green noise. Very high quality. YOU guys are awesome and “Tech Nerd Culture” approves. ## Frequently asked questions about MultiTone Generator PRO ### What types of test tones can MultiTone Generator PRO play?
