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 • Guided camera calibration with Match a Trusted Meter, steadier readings, and low-light guidance • Remembered 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, development results, and protection for unsaved changes • 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 three launches are ad-free. Startup never waits for an ad after the main screen is ready. 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.

Blurize is the private way to hide faces and license plates in your photos and videos — and it all happens 100% on your device. Your media never leaves your device. No account needed. Just open, blur and save. Protecting kids in a holiday video, hiding bystanders before you post, anonymizing a dashcam clip or a screen recording: Blurize finds every face and plate automatically and lets you choose exactly which ones to conceal. WHY BLURIZE 100% OFFLINE & PRIVATE Everything runs on your phone. Your photos and videos never leave your device — turn off your internet and Blurize still works. This is our core promise, not a setting. AUTOMATIC FACE DETECTION Every face is found in a single tap and shown as a thumbnail. Pick the ones to hide and keep the rest sharp. In videos, faces stay covered as they move — even across camera cuts. LICENSE PLATES TOO Blurize detects license plates in dashcam footage, street videos and photos, and hides them with the same tools you use for faces. CHANGE THE VOICE Stay anonymous beyond the face: make a voice deeper, higher, robotic, or set your own pitch, and hear it before you export. Blurize never uses the microphone — it only changes the audio already in your video. MANY PHOTOS AT ONCE Pick several photos and hide the faces and plates in all of them in one go. SHARE STRAIGHT INTO BLURIZE Send photos or a video to Blurize from Photos or any other app with the Share button. MANY CONCEAL STYLES • Gaussian Blur — smooth, natural censoring • Pixelate — classic mosaic look • Black & White — desaturate the face • Solid Color — cover with any color • Emoji Stickers — fun overlays that follow movement Oval or rectangular masks, plus manual boxes you can draw and track across the timeline. YOUR WORK IS SAVED Every import becomes a project on your device. Close the app and come back later — your scan and edits are exactly where you left them. WHAT YOU SEE IS WHAT YOU GET The preview uses the real export engine, and export runs on your phone's own hardware, straight to your gallery. FREE & PREMIUM Free includes blur and pixelate, photos, and videos up to 1 minute. Blurize Premium unlocks: • Videos up to 10 minutes • No Blurize watermark • All conceal styles — B&W, color, emoji • Export in original quality • Ad-free experience Payment is charged to your Apple ID at confirmation of purchase. Subscriptions auto-renew unless turned off at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://blurize.app/privacy No microphone access. No face recognition. No collection of your media — ever. Your photos and videos are yours, and they stay that way.

Verdict
The clearest difference is ads: ReciproMeter at none against Blurize's shown. Blurize's advantage is device support (3 vs 1) and iOS requirement (15.5 vs 18.0). On price, update cadence and in-app purchases there is nothing between them.
