4 years ago, I released a completely rewritten version of what was formerly iSlsk - a Soulseek client for the first iPhones and iPod touch - that was later renamed to MewSeek due to copyright issues on the "slsk" trademark. This new revamped version left behind the Soulseek protocol to become a much faster tool for getting and streaming music content on your phone without the need to use a computer, by taking advantage of several search engines that existed on the web.
Since then, it remains one of the most used iPhone apps for a somewhat controversial purpose, but given its popularity, I always decided to maintain it for free over the years, while accepting a registration fee for enabling additional features such as adding your downloads to the device's music library - a feature that no other app was ever able to replicate until pretty much recently.
As of right now, it works on all iPhone firmwares ranging from 2.0 to 6.1. It remains unchanged since a long time ago, with occasional updates fixing bugs or adding compatibility for major iOS releases -which is broken every year due the fact that MewSeek relies heavily on Apple's private undocumented frameworks and other jailbreak-only features. At this moment there is a work in progress to bring a completely rewritten, much more reliable version (that'd be v3.0) but is progressing significantly slower than before given the other parallel projects I happen to be working on.
However, its great to see that my first public project for a mobile platform is still popular and widely used and I hope I will be able to make it even better in the future :)
If you are finding out about it for the first time, I suggest visiting its own official website for more information!
