Audiohand is an excellent, free iOS application that will work on both the iPhone and the iPad. If you are looking for an excellent way to record audio to your iOS device then I highly recommend you checkout Audiohand.
Audiohand works with multiple devices, you can connect more than one iPhone or iPad to the application, simply by selecting ‘Group’ and creating a password protected private connection; you can also create a public connection that will allow anyone with the app to connect to the group without the need for a password. I tested out recording on two separate devices (iPhone 6, iPhone 6s) and it worked flawlessly for me. I have not yet tested the app with an iPhone and an iPad, but I assume it will work the same.
"Creating Hi-Def Audio with Multiple Phones, for Easy & Powerful Multi-Tracking, Anywhere."
Once you are finished recording, Audiohand automatically works its magic and mixes your track, performs noise reductions and polishes your audio track. You do have the option to export an original version as well, if you do not want the mixed version from Audiohand. You can share out your track to places like Twitter, Soundcloud or email it to yourself, as well as share it to other applications on your iPhone or iPad if they are supported or support audio files.
If you are a musician or maybe even a podcaster and you are looking for a beautifully designed application to record audio, and an application that works flawlessly, I highly recommend Audiohand.
