About this app
Do your eyes feel tired during the night reading on the phone?
Do you have trouble sleeping after constantly staring at your phone screen?
This is caused by blue light. Blue light from your phone and tablet screen is the visible light spectrum (380-550nm) for circadian regulation. According to scientific studies, exposure to blue light imposes serious threats to retinal neurons and inhibits the secretion of melatonin, a hormone that influences circadian rhythms. It is proven that reducing blue light can greatly improve sleep.
Blue light filter is used to reduce blue light by adjusting the screen to natural color. Shifting your screen to night mode can relieve your eyes strain, and your eyes will feel at ease during night reading. Also, a blue light filter will protect your eyes and help you sleep easily.…

Themes reported by reviewers
No theme reported
Counted from the reviews we have read for this app. "No theme reported" means no theme reached our reporting threshold — it is not a finding that nothing is wrong with this app, and we do not say it is.
Five-star share of ratings
65–79% five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.
In the app package we scanned
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.

Method and limits
How a review signal works
A review signal is produced automatically from public app reviews by a classifier — never by a hands-on Appworthy test, and never by a human analyst. It exists so a real, not-yet-audited app can carry more than a blank “Not yet tested” listing, without ever being mistaken for an assessment.
A theme only appears above once at least 5 distinct reviews corroborate it — one angry review can never tag an app. These thresholds are published settings and may be tuned as coverage grows.
It carries no confirmed findings — reviews are one kind of evidence, and nothing here has been hands-on tested. The moment Appworthy publishes a full assessment of this app, it replaces this signal, permanently.
Limits of this report
- A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
- Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
- Not assessed is a state. It is never a zero and never a pass.
- A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review replaces this review-derived signal with hands-on, recorded measurements. Hands-on inspections are not yet open.
