ComPhysics Green UV vs NoteBay

IMPORTANT: This app requires the ComPhysics CP-UV01 UV Indicator and CP-UV01-SA smartphone accessory. Without the dedicated optical hardware, the displayed values are not valid UV measurements. ComPhysics Green UV uses the iPhone camera to analyze the green visible emission produced by the CP-UV01 optical system. It provides a relative UV signal called CRU (ComPhysics Relative UV) and helps you compare conditions, save results, and observe changes over time. KEY FEATURES • Real-time CRU display • Movable circular Region of Interest • Reference-versus-sample comparison • Relative effective UV transmittance and blocking display • Time recording with graph • Photo and reading capture • Sample names and notes • Local export of CSV, JSON, JPEG, and PDF files • Optional location and device-orientation data for records • Korean, English, Japanese, and Simplified Chinese PRIVACY Camera frames and measurement data are processed on the device. The app does not include advertising or third-party analytics SDKs and does not automatically upload measurement data to ComPhysics. Files leave the app only when you choose to share or export them. MEASUREMENT NOTICE ComPhysics Green UV is a relative comparison tool. It is not an absolute UV irradiance meter, certified spectroradiometer, medical device, safety-certification system, or official spectral transmittance instrument. Results depend on the iPhone model, selected camera, settings, accessory alignment, ambient light, distance, angle, source spectrum, and measurement geometry. A low reading does not prove that a UV source is safe.

NoteBay keeps your notes on your iPhone and in your own iCloud. There is no account to create and no subscription to pay. Jotted down on the go. An address, a thought for later: the home screen widget starts a new note with one tap. Later, full-text search finds it again, whichever folder it ended up in. A note is more than a text box. You write in blocks: paragraph, heading, bulleted list, numbered list, checklist, quote, divider, code and image. Type "- " or "[] " and you get a bullet or a checklist right away, no menu needed. Text can be bold, italic, strikethrough or inline code, and links stay links. A whole note can take one of nine colors so you spot it in the list without reading a word. Room to keep things in order. Nest folders as deep as you like. Favorites for what you use often, an archive for what is done, and deleted notes wait 30 days in the trash before they go (you can change the period). Any single note can be shared as Markdown or saved to Files. Written on the iPhone, continued on the Mac. Everything goes through your own iCloud, and there is nothing to set up. NoteBay works offline and syncs when you are back online, block by block: change one paragraph on the iPhone and another on the Mac, and there is no conflict. On the Mac, any note can float as its own window above the app you are working in, half transparent and always on top. That is also where tables and the full library export live, and where you can open your library to AI assistants through a local MCP server, folder by folder and only when you allow it. Tables made on the Mac are shown on the iPhone. No subscription and no ads, now or later. NoteBay is free for up to 10 notes, with every feature included. After that, a single purchase unlocks the library for iPhone and Mac together, Family Sharing included.
