Love it so much! I'm a very creative person, so I adore customizing my electronics with this. The level of customizations you can make is insane, I've spent like 6 hours all together customizing my phone & tablet lol To have it all come in an app by a trusted company, no ads, no worries, for free is amazing. I have so much fun making themes and setting up my phone to be easier and more accessible for my wants and needs. It's great, highly recommend!Set up SmartSwitch too so you don't lose stuff!

I love this app, finally I can get my phone looking different to everyone else's. I just wish it had a font style setting on it instead of paying ££££'s for unusable downloaded ones or,plain boring ones on the app store. Still it's a cracking app I recommend it to people like myself who want to stand out from the crowd. Keep up the good work Devs.
