Beyond the basics
JustFlip!, taken further.
For learners who never stop.
Underneath the flip is a growing set of tools for people who study seriously: your own AI tutor briefed on exactly what you're struggling with, tracking for skills no test can grade, a clear picture of how your memory is really trending, cards that say precisely what you tell them to, code that reads like code, decks you already own elsewhere, and a backup story that never leaves your progress to chance.
Seven ways to go further.
A quick map of what's below — tap anything to jump to it.
Ask AI
Turn your mastered and missed cards into a tutoring session with your own AI.
ProProgress trackers
Track guitar songs, gym routines or any skill a flashcard can't grade.
ProAdvanced statistics
Retention trends, a streak heatmap, deck difficulty and a review forecast.
Spoken, your way
Write "iOS", have it read as "eye oh ess" — you decide what's spoken.
Code that reads like code
Fenced code blocks get real syntax colors across 18+ languages.
Bring what you already have
Import decks straight from a CSV spreadsheet or an Anki export.
Your data, always safe
Sync, automatic backups and a 30-day undo — three independent layers.
Ask your own AI — with real context.
After a while, JustFlip! knows something no chat AI does: exactly which cards you've mastered and which ones you keep missing. Ask AI turns that into a clean, readable report — hand it to ChatGPT, Claude or Gemini and get tutoring that actually knows your gaps. JustFlip! never calls any AI itself — it only ever prepares the report; you choose if and where it goes.
- Teach me the prerequisites — identify the background knowledge behind what you keep failing, and teach it from the ground up.
- Explain what I keep getting wrong — focused explanations and mnemonics for your struggling cards.
- Recommend sources — books, docs and courses ordered by your actual gaps.
- Create cards for my gaps — get new cards back in JustFlip's import format and close the loop.
Pro Single-card reports are free. Full deck and interest reports — the ones that reveal your whole failure pattern — are part of JustFlip! Pro.
Track what a test can't grade.
Some things aren't a recall problem: a guitar repertoire, a gym routine, a long-running project. A progress tracker lives right inside your deck as a name and a self-judged completion bar — you move the slider, nobody quizzes you. Trackers are strictly outside spaced repetition: they never enter your review queue, never affect streaks or due counts, and blend gently into deck mastery so a "Songs" deck reads its real progress instead of 0%.
ProSee your memory, not just your streak.
A deeper statistics screen turns your review history into an honest picture: is retention actually improving, is a backlog building, which decks are genuinely hard? It's built to answer "am I learning better, not just more," not to decorate a dashboard with vanity numbers.
ProMature retention up 7 points since your last dip.
14-day streak · darker means more reviews
Are you actually improving?
Overall vs. mature retention over 7/30/90 days — the number that matters more than any streak.
A habit you can see
A GitHub-style calendar of every study day, plus your current and longest streak.
Know what's coming
A ranked view of your hardest decks, and how many cards are due over the next 7 or 30 days.
Hear cards exactly how you wrote them to sound.
JustFlip! already reads your cards aloud. The advanced part is control: any word, formula or image can carry its own spoken form, separate from what's shown on the card. Write the abbreviation, spell out the pronunciation — text-to-speech says what you meant, not just what's on the page.
Do you know how to enable iOS background app refresh?
"Do you know how to enable eye oh ess background app refresh?"
Pro Writing spoken overrides is free. Background listening — a Live Activity that keeps a deck playing on your Lock Screen while you walk, cook or drive — is part of JustFlip! Pro.
Code that reads like code.
Fenced code blocks in your cards get real semantic highlighting — keywords, strings, comments, numbers, types and function names, each their own color — across Swift, Python, JavaScript/TypeScript, Java, Kotlin, C/C++/C#, Go, Rust, Ruby, PHP, SQL, Bash, JSON, YAML and more. No third-party library, no setup: just fence your code with a language tag.
func retentionRate(_ reviews: [Review]) -> Double {
// share of reviews graded good or easy
let good = reviews.filter { $0.grade >= 2 }.count
return Double(good) / Double(reviews.count)
}func retentionRate(_ reviews: [Review]) -> Double {
// share of reviews graded good or easy
let good = reviews.filter { $0.grade >= 2 }.count
return Double(good) / Double(reviews.count)
}Bring what you already have.
Switching from a spreadsheet or from Anki shouldn't mean retyping years of cards. Drop in a CSV — or an Anki export — and JustFlip! reads it directly: no AI step, no reformatting, just your existing decks, in your library.
Your progress is the one thing that can't be re-typed.
Card content can always be re-imported. Every response, interval and ease factor cannot. That's why data safety isn't one feature — it's three independent layers: live iCloud sync across your devices, silent automatic backups to your own iCloud Drive, and a manual export you can trigger any time. Delete something by accident? It waits 30 days in Recently Deleted before it's ever really gone.

Advanced, without the noise.
Every one of these stays true to the same idea: JustFlip! reports, tracks and backs up in the background — you decide what leaves the app, and when.
