ManaBox vs Delver Lens vs Tappr
Shared ground
All three help you digitize physical Magic cards with camera-based workflows and market-aware pricing. Differences show up in platform focus, UI polish, and how much non-scanning product surrounds the scanner.
ManaBox
Broad companion app energy: scanning plus lots of player utilities. Ideal if you want one icon on your phone for many MTG jobs.
Delver Lens
Throughput and export culture, especially on Android. Ideal if you think in CSV and bulk sessions.
Tappr
Scan → live price → collection/set tracking on iOS and Android, with pricing sourced via Scryfall. Ideal if that loop is the whole product you wanted.
Try before you standardize
Scan the same foils and old-border cards in each app you are considering. Keep the one that matches your platform and misreads fewer printings.
