DisparaTimer vs Camdex

DisparaTimer is a mobile app that, when connected to a Raspberry Pico W/WH, can control the exposure time of a photographic enlarger using a power relay. The physical setup is inexpensive and easy to assemble. DisparaTimer has two operation modes. The first is a traditional timer mode, where you set a specific time for each exposure. The second is designed for creating test strips with constant fractional step increments over a base time. On iPad (iPadOS 17 and later), DisparaTimer includes a landscape-only notes panel that lets you add photos or images of your test strips and make handwritten or visual annotations directly on them.

Camdex is a collection tracker built to help camera collectors catalog and grow their collections. Catalog, organize, and appraise your vintage Leica, Nikon, Canon, Sony, Olympus, and Polaroid gear—from film SLRs and rangefinders to mirrorless bodies, lenses, and film stock. Just take a photo and we will instantly identify the brand/model/specifications and any visible serial numbers to make documenting your entire collection easy. I built Camdex because I collect vintage film cameras and needed a better way to track my own collection. Whether you're cataloging a lifelong vault of equipment or trying to identify a mystery find at a dusty flea market, Camdex is your ultimate companion. TRACK YOUR COLLECTION The collection tracker your camera shelf deserves. Keep a complete inventory of every body, lens, and accessory you own—organized however your brain works: SLRs, rangefinders, Zeiss folders, Leica glass, Soviet shooters, Polaroids, or modern mirrorless. Log serial numbers, focal lengths, apertures, and lens mounts, plus attach your own photos and personal notes to every entry. Your whole catalog, always in your pocket. INSTANT IDENTIFICATION & APPRAISAL Spotted a camera at a thrift store, estate sale, or flea market and have no clue what it is or what it is worth? Snap a photo, and Camdex will instantly identify the brand and model—along with up-to-date market data—so you can make an informed purchase. SHARE VIA EXTERNAL WEB LINK Show off your collection with a single, read-only web link. Publish your catalog as a clean web page that anyone can open in their standard mobile or desktop browser—no app download or sign-up needed to view. You're in control: share your whole collection or just a specific group, choose whether to include purchase prices and notes, and revoke the link any time. Serial numbers are never shared. LIVE MARKET PRICES Stop playing guessing games about what your camera is worth. Tap any item to see current market prices based on real, active listings—a price guide that's never out of date. Camdex pulls live data straight from eBay to calculate average asking prices and confidence scores. Choose your specific region (US, UK, Germany, etc.) and currency, so you always know the market value where you live. QUICK IMPORT & CLOUD SYNC Import your entire collection and appraise it in seconds. Bulk upload photos of your cameras and let the app's auto-identification fill in the blanks, or upload a CSV/ZIP file. Create a free account to securely sync across all your devices, or go off the grid and use it anonymously. WISHLIST & DEAL HUNTING Keep a wishlist of the gear you're chasing with target prices. Camdex shows you active eBay listings for each item so you can jump on a deal the moment it drops. EXPORT YOUR DATA No app lock-in.
