5 stars: I've been using this app for well over a year. It has the perfect amount of flexibility and adaptability for my needs. I notice Android shuts it off at times, but PowerLine has a method of rebooting itself that makes the down time only brief - it's there when you want it. A great app, 5 stars.
5 stars: Android signal strength indicators (baterry, too) are as they were since beginning - very discrete, and usually useless. Since my eyesight deteriorated, it is even more obvious to me. Not that one must act as flight engineer, monitoring all aspects of a phone, but essentials should be obvious. With a help of this app that can be achieved, in an obvious way, blended with a design at the same time. Meaningful and usefull for me.
4 stars: This is great! I can keep tabs on my data at a glance (since Pie update, my data widget hasn't worked!) without having to go through the settings menus. I tried it at the bottom but it rests above my navigation bar... I thought it would overlap it. If it would overlap the nav bar like it does the notification bar, it'd be an easy 5 star app!
4 stars: Interesting and useful. Keeps screen clear without getting in the way of other information that you want. Configurable enough to be useful yet not difficult in options to choose.
3 stars: Very nicely designed. Excellent at showing statuses of your battery's charge, wifi status, and so on. However, at least for me, the app will not autostart on bootup on my Lenovo tablet. So, ...
