1. Watch your ears though..some of the frequencies are super high!It would have been so good if you had put a logarithmic scale... now we have 2 high octaves taking the complete left half and all the lower tones are so easy cause.. yea I dont know what to say just put logarithmic god damnitMore variety of tones and the ability to pay a couple dollars instead of watching ads would be appreciated.The app is ok however when playing this app anyone that is using it should be cautioned and the app should only be used outside or if played inside must be careful due to it could cause some issuesPerfect for training the ear 👌Very simple but works fineContains undisclosed ads!!!cool app.
2. to check out the HZ on you tube.😁Perfect !Range of hearing is 20 Hz-20,000 Hz this app only goes to 10 kHz which is kind of disappointing.
3. It would be nice to have a repeat function so we could play the frequency a few times just to get used to it before it changes.
4. Pretty good.
