iTunes is the only option Apple gives us for loading media onto our iPhone, iPad or iPod touch from our Macs, and it limits the audio and video file formats we can upload. That's a thing of the past thanks to WALTR from Softorino. This awesome Mac app lets you upload a long list of file formats — such as MKV, AVI, MP4, CUE, FLAC, APE, ALAC, OGG, AAC, AIFF and WAV — to your iOS device without ever touching iTunes. Just fire up WALTR, connect your iPhone or iPad to your Mac via USB, and drag files to convert and upload them so you can watch or listen on the go. It really is drag-and-drop simple, and file transfers are surprisingly fast. You can try out WALTR for free and a license costs US$14.97.
