Product focus
What LumiSignal is built to help with.
A cleaner detail page explains the product quickly, then lets visitors move to the store, privacy page, or support without digging.
Run signal modes intentionally
Start SOS, beacon, or strobe flows with LED, screen, or both sources, plus photosensitivity warnings and signal auto-stop controls.
Keep controls close and local
Quick Settings, widget, shortcuts, notification controls, settings, haptics, and onboarding state are stored or handled on-device with no Internet permission.
Experience design
Designed around clearer actions, not clutter.
Each app detail page uses visual rhythm, simple content blocks, and small snapshots instead of heavy text sections.
Torch
Turn on light with clear status
The torch screen shows active state, brightness, auto-off choices, and hardware fallback messaging when a device has no usable flash.
Screen
Use the phone display as a light
Screen Light can fill the display with selectable colors and brightness while restoring device brightness when the light session ends.
Signal
Choose SOS, beacon, or strobe
Signal modes focus the screen on start and stop controls, source selection, timing, safety notices, and visible active-state feedback.
Store
Store link ready when published
The page keeps the store area ready so a future Google Play link can be added without redesign work.
Privacy
Privacy and terms stay easy to reach
Every app keeps its legal route available from the catalog, detail page, and support directory.
