Sprokbook vs Expose

You get your scans back and the first question is: when did I take this? Which roll was this — Ektar or CineStill? Sprokbook gives your analog camera digital powers — the when, where, and what of every frame you shoot. SHOOT, TAP, ADVANCE One tap captures the time and GPS coordinates. Include a reference photo so you can match frames to negatives when your scans come back. KNOW WHAT'S LOADED IN EVERY CAMERA Forgot whether you loaded Portra 400 or 800? Sprokbook tracks your cameras, the roll in each one, and how far through it you are — all at a glance. Switch between bodies mid-shoot or load a new roll without losing track. SHOOT WITHOUT BREAKING YOUR FLOW Instantly log exposures from the Action button and your Apple Watch with a Shortcut. Log without opening your app or even picking up your phone. REMEMBER EVERY ROLL, STOCK, AND FRAME Scroll back through months of shooting and see the full history — which stocks you've been running, where you've been shooting, how your habits have changed. Your shooting life, organized by camera and roll. EXPORT YOUR DATA Save to CSV or JSON for analysis, archiving, or scripting. Everything — location, timestamp, film stock, frame number — comes with you. BACKED UP WITH ICLOUD Your full shooting history stays backed up and synced via iCloud. Start on one device, continue on another. YOUR DATA IS YOURS Sprokbook does not collect any data. Your location and photo data stays on your private iCloud account. No accounts, no tracking, no telemetry, no ads. Period.
