Luminosys vs FoldLight

Luminosys allows you to accurately measure the ambient light level in Lux or Foot Candles (FC). To do this, Luminosys uses your phone's camera in conjunction with a piece of paper to accurately measure the light level. It is very easy to use and is a great app for those looking for accurate light measurements for photography, comparing light sources, or indoor gardening.

FoldLight is a widget-first controller for the lights on your own Home Assistant server. Put your lights on the Home Screen, Lock Screen, and in Control Center — then toggle, dim, warm, or recolor them without ever opening an app. There's no FoldLight account, no cloud, and nothing to sign up for. Paste your Home Assistant address and access token once and you're set. FoldLight talks only to the server you already run. WIDGET-FIRST CONTROL Small and medium Home Screen widgets with a power toggle, brightness steps, and preset swatches — each one acts directly on your lights, no app launch required. KNOWS EACH LIGHT Every light shows exactly the controls it supports — on/off, dimming, color temperature, or full color — detected automatically from Home Assistant. PRESETS Save Warm, Focus, Movie, or your own scenes and apply them from a widget or from Control Center. CONTROL CENTER & LOCK SCREEN Toggle your main light or apply a preset straight from the iOS system controls. LAUNCHER TILES, SIRI & SHORTCUTS One-tap tiles to Home Assistant or any page you use, plus App Intents for every action so you can automate them or ask Siri. TRY IT WITHOUT A SERVER Demo mode is on by default and works with sample lights, so you can explore everything before connecting. PRIVATE BY DESIGN FoldLight collects nothing. Your server address and token stay in your device's Keychain and traffic goes straight to your machine — over your LAN or securely over Tailscale.
