The MTG scanner app market offers several free options, but the word "free" comes with different meanings depending on the app. Some apps are completely free with no limits, some offer a free tier with caps on collection size or exports, and some require a subscription for any useful functionality.

TCGPlayer's app is the most well-known completely free option. You can scan unlimited cards and access the full TCGPlayer marketplace. However, the scanner is slow, frequently identifies the wrong set, and the app has a 2.2-star customer rating due to reliability problems including data loss when the app closes unexpectedly. It works, but you will spend extra time correcting scan errors.

Lotus Scan offers a generous free tier that includes core scanning, real-time pricing, and collection management. The scanning accuracy and speed are the same on the free tier as on premium. The free tier gives you enough functionality to catalog a collection and track prices without paying anything. Premium adds advanced features like price history charts and enhanced collection analytics.

Helvault is another free option for iPhone users with unlimited collection size, no ads, and iCloud sync. It is simpler than Lotus Scan with fewer features, but it is genuinely free with no hidden limits. ManaBox allows five free decks and basic scanning, but the white background requirement and scanning issues with foils limit its usefulness. Delver Lens is free to scan but limits exports to 100 cards on the free tier.

The best approach for most players is to start with Lotus Scan's free tier, which gives you accurate scanning and reliable collection tracking at no cost. If you find yourself needing advanced analytics or additional features, the premium upgrade is available when you are ready.
