About Tideo Auto Brightness

You taught Android your brightness preferences and it is still wrong. Tideo

replaces the opaque on-device ML of stock adaptive brightness with deterministic,

inspectable math: a tunable lux-to-brightness curve you can see and shape, smooth

animated transitions, circadian (time-of-day) scaling, per-context overrides, and

an optional privileged "super dimming" mode that takes the screen below the system

minimum.

To use it, first disable the system's stock Adaptive/Auto Brightness

(Settings > Display), then launch Tideo, complete onboarding, and toggle the main

service on from the Dashboard.

Features:

* Three-zone perceptual brightness curve with a live, editable graph.

* Automatic curve fitting: adjust brightness by hand during normal use and, after

a handful of points across varied lighting, the wizard suggests a fitted curve.

* Reactivity control: per-range dead zones that kill sensor jitter without making

the screen sluggish.

* Smooth animated transitions with override detection: drag the system slider and

Tideo steps aside, then resumes per your rules.

* Circadian scaling synced to local sunrise/sunset, shifting the whole curve

across the day.

* Super dimming (privileged): drives Android's Reduce Bright Colors below the

hardware floor, plus a PWM-flicker-aware software-dimming mode.

* Context automation: load profiles automatically by foreground app, time window,

location, charging state, Wi-Fi SSID, or day of week.

* Profiles: five built-in presets plus save / overwrite / factory-restore and

JSON import/export.

What's new in 1.15.0

New: - Bright-light hand-off: above a lux you set per profile, Android's Adaptive Brightness takes over so the phone's sunlight boost works, and Tideo takes back below it. Set it in Menu → Hand-off Behavior - a message marks each switch; the notification, widget and tile say "Android" meanwhile - calibrate the display there to see Android's brightness, above 255 when High Brightness Mode boosts it
