sFilter- Blue Light Filter Pro

Works exactly as described. Lots of useful features, including scheduler and widget. DEV SUGGESTION: Would like to see a settings toggle that disappears the widget when all apps or individually specified apps are open, perhaps even just as a paid feature. Even without that feature, I still highly recommend sFilter Pro.

Since June update there is no icon on notification bar. Have to uninstall and reinstall to make it work. Icon randomly disappears from notification bar.

On Android 8.0 (Oreo), the filter does not work on the notification screen. Please update the app.

When the app is moved to SD card, navigation bar is no longer available with filter options. I tried several ways but in vain. Kindly, look into it. Other than this there's no glitch to point out at. When it crashes, reopens on its own which makes this application awesome. Thanks!

The free version pretty much had everything I needed, although being able to adjust the floating widget to a fixed location is a nice plus. I also employ an ad blocker on my device, so that wasn't a problem. But sometimes an app is so good, like this one is, I felt obliged to buy the premium version as a way to say thanks to the developer.

Seriously my LG G5 screen burn is gone. Thanks... But can you please update your good app by removing the notification... I give 5 star if remove...

Tried many and this seems to work best for me. The auto on/off is great and never fails. Set it and forget it. You can always easily turn on the filter manually. The free version is good so I purchased to support the Dev. Only suggestion is to increase max dim level.

Stunningly clever. Tried many but this is the ducks guts! Now I love my new MI so much more. Thank you for your fantastic app.

I've relied on my phones blue light feature but still felt eye strain. I've tried many remedies over the last 2 years, nothing helps me like this app. Thank you, thank you, thank you.

Tried quite a few. This one is so user friendly and feature rich. Awesome job! Thank you for all your hard work!

The free version was so good, I had to buy.

Paid for this Pro version because it is worth it. Same again, 5 stars.

Doesnt dim virtual buttons at bottom of screen...

Tried a few and this one just works. Easy shortcut setup, not permanently in the notification bar like most (can be if your want to). Please remove the Buy Pro option from the Pro version!

everything is okay only the timer and don't work

Tried all others and this one is the best of all.

The timer doesn't appear to work. In addition, I set the app so it works when the phone boots up, but again, it doesn't appear to work.

If the app is on all night it drains my battery and causes my phone to get really hot

This app does a really good job and is well worth the $1.98.

Great app nice interface. Only wish it could go to 95%. I used a different filter and it could get even dimmer.

Good App for protecting our EYES

I've had it for few hours now. Works so far but now only time will tell.

Saw the reviews on the free version and saw how the creator responded to reviews and was active in the comments so I decided to try it out and it was great, I wanted to support such a developer so I got the pro version. Unfortunately it shuts down from time to time. It doesn't stay on always which is incredibly frustrating. In not sure if its the app or my tablet (which it very well could be its a 2 year old LG gpad) . ill try it on my new LG g5 and see if it does the same thing.

Working good on a Note 4.

It will work for 5 min then phone forced the screen back to stock.Needs improvement.
