Blue light - Avoid Eye Strain

This application creates the special filter which reduces the blue light that comes from screen.
A blue light is reduced and the burden of eyes is eased.
Unlike the sheet physically stuck on the screen, a filter can be displayed easily.
A color and transparency can be set up freely.
Four kinds of filters (amber, an orange, wine, energy saving) have preset by default.






===== Ultralight low load =====
There is no display of an advertising column.
Network communication does not occur, either.
An unnecessary ornament, processing, and acquisition authority were eliminated as much as possible, and pursued low load thoroughly.

The processing which always such as a timer schedule and background service continues moving is not used.
When displaying the filter, there is no execution load.
You can use without not giving a damage to CPU and a battery.
Moreover, you can use it without caring about monthly data traffic.

*When it is the load zero, it is recognized as "app doesn't exist".
The booster function which "raises filter intensity" in order to avoid it was recorded.
In order to tell "app's existence" to Android, misrecognition is prevented by applying a little loads purposely.
In that case, it stops being "no execution load."
