5 stars: Definitely worth the $11 I spent on premium and the companion app for my watch. At first I wasn't sure about the price but as I started playing around with the app I realized the customizations are almost infinite. Although most faces on this app are paid, I've been able to find so many watch faces online for free and all of them are able to be customized!
3 stars: This does its job, for better or worse. The app itself allows you to load any watchface they host or can import, but at a huge performance drop. Like insane. Even the phone app lags my Note 8, which is a feat in itself, but the Wear OS companion app lags any watch with any watchface. This app really needs some optimization on both sides.
5 stars: a lot of options and tons of customizing available if you want to make your own watch face. or you can change an existing one that someone else submitted to the app. Definitely recommend this app, but you want to purchase the premium version. its a one time payment but unlocked way more options for you.
4 stars: I really like this app. Love being able to create my own faces. Easy and simple to use. I only wish that the step counter and heart rate were accurate. If they were I would have given 5 stars instead of 4.
3 stars: All functions work well. Except the Premium baiting. States you can 'try' it, you can't without paying. States a 50% off discount, still charges full price. Don't offer discounts if you're not going to follow through with it.
