Meet HALO
HALO filters out the blue light that's hard on your eyes and dims your screen to a comfortable level in the dark — so you can look at your phone before bed and still drift off naturally~ :-)

When to use it
- You want to cut the harmful blue light coming from your screen
- You want to dim the bright light that keeps you awake before bed
- Your phone's built-in blue light filter just doesn't feel like enough ^^;

What's inside
- Night mode (blue light filter) on/off
- Intensity and brightness control
- Quick settings from the notification panel (basic/advanced)
- Night mode on/off from the Quick Settings tile
- Scheduled night mode on/off ⏱
- Enable/disable the app (stops the background service)

There's more
- Scheduled night mode on > only when you're home: at the scheduled time night mode turns on if you're at home. (It stays off while you're out.)

Permissions we need
- Receive data from the internet: needed for in-app purchases and ads.
- View network connections: needed for in-app purchases and ads.
- Full network access: needed for in-app purchases and ads.
- Run at startup: needed to start HALO automatically when your device boots.
- Draw over other apps: needed to show the blue light filter on top of your screen.
- Keep the device from sleeping: needed to make sure your schedules run on time.
- Accessibility service: needed to extend the filter over the notification panel. (Optional — see below)

About the accessibility service
The notification panel is a system area a normal overlay can't cover so we use the accessibility service for that one purpose only.
- We never read collect or store anything shown on your screen
- We don't subscribe to any accessibility events
- We never act on your behalf
It's optional. Leave it off and everything else in HALO works exactly the same and you can turn it on or off anytime in the app's "Notification panel settings."

Good to know
- HALO runs as a foreground service (a background service with a persistent notification) so the system won't shut it down while you're using it.
- It never drains your battery on a timer or does anything unnecessary in the background so you can use it with confidence~
- The 4 filter colors you can pick look different from the actual filter~ In practice HALO removes the blue tones and adds a little warmth blocking harmful blue light effectively.

Free with ads
- Buy the premium version to remove ads and unlock a few nicer features.
- If you like it a 5-star review would mean a lot.
