CARDS FROM YOUR OWN MATERIAL - Paste notes, drop a PDF, Word or PowerPoint file, take a photo of a page, or paste a web link or YouTube video - Every AI card quotes its source and is checked against it before you see it - Question and answer, fill in the blank, both ways, and multiple choice with wrong answers that are actually plausible - 10 generations free; more come by the pack, never as a subscription HONEST SCHEDULING - Spaced repetition that brings each card back just before you would forget it - A daily limit: whatever is past it waits for tomorrow, so a day off never becomes a backlog - How much you remember, shown as a real percentage, not a streak - Ratings show their consequence: Again means the card comes back before the session ends PRACTICE AND TEST - Practice: go through every card and sort it into Know it or Still learning, round after round until you know them all - Test: multiple choice, written and true or false questions made from your deck, scored at the end or as you go - Practice the ones you missed in one tap - Neither one changes your review schedule TEACH-BACK (PRO) Say the answer out loud before the flip.

Verdict
The clearest difference is ads: FlashKeepers at none against Deckbase's shown. FlashKeepers also leads on update cadence (every 3 days vs weekly) and iOS requirement (15.0 vs 17.0). On price, in-app purchases, monetization model and device support there is nothing between them.
