ReciproMeter is a free light meter for film photographers who need dependable long-exposure calculations. Use your iPhone camera to read exposure metadata, select your film stock and aperture, and get an immediate shutter recommendation. When exposure times run long, ReciproMeter applies reciprocity correction using official manufacturer data whenever available. For films where official datasheets stop short, ReciproMeter keeps the distinction clear: • Official manufacturer reciprocity data • Optional community-sourced long-exposure guidance • Optional experimental estimates, clearly labeled as lower confidence Features: • Live camera preview, visible by default, with an optional full-screen exposure view • Camera calibration, steadier readings, and low-light guidance • Manual EV and external meter input with reference aperture and ISO • Exposure lock for holding a reading while composing • Neutral-density compensation, then reciprocity on the longer time • One-stop exposure bracket that follows the film's reciprocity curve • Favorite films and a built-in library with correction charts and source links • Saved film, aperture, ND, and EI presets • Exposure notes with frame numbers and development results • Community and experimental long-exposure tiers as separate opt-ins • Metering ISO / EI override for push-pull workflows • Bulb timer with preparation delays, optional audible cues, and a Lock Screen countdown • Dark mode, light mode, or system appearance Privacy: ReciproMeter does not take or store photos. It only reads camera exposure metadata needed to estimate ambient light. An App Open ad may appear over the loading screen at launch, or on a return to Films, Notes, or Settings after you have been away for at least a minute, at most three times a day. Active metering, timers, note editing, and purchases are protected. The first launch is ad-free. The loading screen shows the Remove Ads Forever price when available. Remove Ads Forever is an optional one-time in-app purchase. It removes all advertising with no subscription or expiration. Purchase or restore it in Settings. Advertising privacy choices remain available from Settings where required.
Shared Album Saver
Read full descriptionHide full description
Shared Album Saver is a local-first photo utility for checking whether photos and videos from shared albums have already been saved to your personal photo library. It is useful when: - A family, travel, event, or baby album contains many shared memories and you want to make sure important items are saved locally. - You are preparing to leave a shared album, switch devices, or clean up old albums without comparing every item by hand. - You want to save missing shared photos and videos into your personal library while keeping a clear import record. Key features: - Scan shared albums and your personal photo library on device to identify saved, missing, possible duplicate, and failed items. - Save selected missing photos and videos into your personal library, with a local destination album created for each shared album. - Review import logs and summaries so each import, skip, or failure has a clear reason. - Use the app without an account, cloud upload, or third-party analytics. Try it free: Scan every shared album and complete your first 10 syncs free. Each sync can include all selected photos and videos. A single lifetime purchase unlocks unlimited syncing. There is no subscription. Privacy and photo access: Shared Album Saver needs Full Photos Access to compare shared albums with your personal photo library accurately. If you allow only limited photo access, scan results may be incomplete. Important note: Shared album photos and videos may be shared copies and may be lower quality than the original files. Shared Album Saver saves the currently available shared copies. It does not claim to recover deleted photos or restore original-quality backups.
