WALTR

The necessity of using iTunes for uploading content from computers onto iOS devices triggered mixed reactions and possibly destroyed friendships ever since its launch. Not only this, but iTunes is not what you would call friendly towards a wide array of formats.
If you find yourself frustrated with iTunes, then you can try third-party apps that offer you faster or better alternatives for transferring files to your iPhone and iPad.

Useful app for iOS users

WALTR is a powerful piece of software designed to make the transfer of media files from your computer to your iOS devices be as smooth and as simple as possible.
It comes with two major advantages: first, it makes it possible for you to upload a large number of typically unsupported media files to your iOS devices without needing to convert them beforehand. Secondly, it enables you to do it by bypassing the whole iTunes shenanigans.

User-friendly interface and fault-proof workflow

The main window of WALTR comes with a limited set of information and with an intuitive window for dragging and dropping your files that need to be uploaded on your device. Alternatively, you can add your files by manually browsing to their locations.
Therefore, the workflow is so straightforward that even the most hardcore Apple fans cannot find reasons to complain, and considering that the other option is going back to using iTunes, they should not either.

Upload videos and music to your iOS devices with just a few clicks

WALTR makes it possible for you to upload MKV, AVI, MP4, CUE, FLAC, APE, WAV and other similar media files to your iOS devices (iPhone or iPad). The utility automatically makes them playable on your device native media players (the Video and Music apps).
In conclusion, with a minimal interface, ridiculously-intuitive workflow and fast transfer speeds, there is no denying that WALTR can become a must have app for all iOS users who are fed up with iTunes.
