Doesn't seem to accept written in frequencies very well.
Nice and simple
Science is awesome
DON'T UPDATE - as near as I can tell, the ONLY change with the latest "update" is the introduction of ads. Even this app's most annoying design failure -- always reverting back to 440 instead of remembering the frequency last used -- remains. So if you have an older version, keep it, it's better than this "update".
Nice app mostly but slider is inaccurate, so I can type number only. Option for different wave type would be nice
- Adds the possibility to use decimals for frequencies.
- On app launch, restores last frequency played.
