I want to get this because of the notistar but I was underwhelmed with it. I got so I can get into lost notifications like the specific tab and details but it doesn't do that. it just brings you to the notification tab that already lost it. like for twitter. Also filtering apps doesn't actually work, sometimes it just gets rid of everything so you just have to put all apps. It's actually so annoying that it doesn't do what it supposed to do.

The top 3 apps are fabulous, sat down with bacon an espresso and crawled into a 2 hour rabbit hole customizing every feature on my phone. There so much more you can do and brought a whole new love using my phone. no issues or lagging, not a single add , obviously checked ea setting to disable notification but honestly theres nothing "odd" in the app.

Most tools are really good. A few, like QuickStar and Wonderland, are completely unusable because they repeatedly crash before you can do anything with them. My favorite modules are Routines+, Sound Assistant, RegiStar, and One Hand Operation +. I genuinely couldn't live without them - and they never crash. If they ever fix the crashing issue, I'll update to 5 stars.
