The Email Reminder Difference
Here's the thing nobody talks about: the best spaced repetition algorithm doesn't matter if you forget to use it.
Both Anki and Quizlet suffer from the same problem—they're apps you have to remember to open. That's ironic for memory tools.
MemoRep solves this with email reminders. When a card is due, you get an email. Click, review, done. No app to open, no habit to build, no "I'll study later" procrastination.
For busy professionals, this is a game-changer. Your review comes to you, not the other way around.

| App | Algorithm Quality | Customization |
|---|---|---|
| Anki | ⭐⭐⭐⭐⭐ Full SM-2+ | Fully customizable |

Frequently Asked Questions
Is Anki still the best spaced repetition app?
Anki is still the most powerful, but "best" depends on your needs. For power users and medical students, yes. For busy professionals, MemoRep's email reminders might be more effective.
Why doesn't Quizlet have real spaced repetition?
Quizlet is designed for test prep and classroom use, not lifetime learning. Their "Learn" mode adapts, but doesn't use the full SR algorithm that optimizes long-term retention.
Do I need to pay for these apps?
Anki is free on desktop and Android (iOS costs $25). Quizlet has a decent free tier. MemoRep has a generous free tier that works for most users.
Which app is best for language learning?
Serious language learners prefer Anki for its audio support and massive shared deck library. Casual learners might prefer Quizlet for pre-made sets.
Can I switch between apps?
Yes, but it's not seamless. All three support some form of export/import, but you'll lose formatting and scheduling data. Best to pick one and commit.
What if I keep forgetting to study?
That's exactly what MemoRep solves with email reminders. If you've abandoned other apps because you forgot to open them, MemoRep is worth trying.
The Bottom Line
There's no universal "best" spaced repetition app. The right choice depends on who you are:
Choose Anki if: You're a power user who wants full control, doesn't mind a learning curve, and needs offline access.
Choose Quizlet if: You're a student who wants something easy, studies with classmates, or needs pre-made content fast.
Choose MemoRep if: You're a busy professional who wants the benefits of spaced repetition without the complexity—and especially if you've abandoned other apps because you forgot to use them.
The best app is the one you'll actually use consistently. For many people, that's the one that emails them.
