Man, I tried using Shelter, but I didn't have a good first impression of it. I went to download it and saw that it seemed to have a pretty simple design, but what caught my eye was the fact that it was last updated almost 3 years ago. I hesitated for a moment but tried to ignore that and went ahead and installed it: when I went to use it, it bundled about 6 apps without me asking, the app I actually wanted to bundle stopped working, and the others it bundled without my permission became extremely slow. Not only that, but my whole phone in general got really sluggish, lagging and all that. I didn't have a good experience with it and I don't plan on using it again.
