Tideo Auto Brightness Automation app for Android description
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 systems 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 Androids 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.
- Live Debug scene: a glass-box readout of every runtime variable and decision.
- Emergency recovery: flip the phone upside-down and shake to force brightness to max with an SOS vibration.
- Surfaces: foreground-service notification with actions, a Quick Settings tile, a home-screen widget, and boot-start.
Privilege tiers:
The core pipeline is fully functional at the BASIC tier, which uses only the user-grantable WRITE_SETTINGS permission. The optional ELEVATED tier unlocks super dimming and requires a one-time WRITE_SECURE_SETTINGS grant that YOU perform via adb, Shizuku, or root. It is never granted automatically.
About the permissions Tideo requests:
- Background location and location: used only by the optional location-aware context rules and the once-a-day sunrise/sunset refresh for circadian scaling.
- Usage access (PACKAGE_USAGE_STATS): used only by per-app context rules to read the foreground app; granted from a Settings screen, not a runtime dialog.
- Accessibility service: optional and presentation-only. It draws the debug/context flash overlay system-wide. It does not read screen content and does not consume input events. With it off, Tideo falls back to a foreground toast.
Privacy:
Tideo is local-first with no analytics, ads, or accounts. It makes one outbound network request, and only as a last resort: if you opt in and enable circadian scaling and no on-device location is available, it falls back to a single HTTPS request to ipwho.is to estimate your city from your public IP. This fallback is off by default and can be turned off under Circadian > Date & location. Automatic lookup runs at most once per day, and the resolved coordinates are saved only on-device; the user-triggered Use current location action can make an additional request after on-device location fails. Everything else runs entirely on-device.
Tideo is a ground-up Kotlin/Compose rebuild of the Advanced Auto Brightness Tasker project, ported with exact behavioural parity. It is not affiliated with Tasker.
