Three taps.
That's the loop.
Pick
your jungle
Six free B1–B2 decks. Six premium C1–C2 decks. Business, Tech, Sport, Science, Travel, Health & Medicine — pick the ground you actually walk on.
Take
a guess
A real sentence with a blank. No flashcard "list of words" feeling — every card teaches a word the way you'd actually meet it in the wild.

No SM-2. No intervals. No streaks to protect. Just you, the word, and the truth.
Burned
the
algorithm.
Most flashcard apps schedule you. Sage Ape doesn't.
We threw out SM-2, intervals, streaks, XP, and every other dopamine knob. The study loop is the product. You see a card. You guess. You flip. You decide if you caught it. That's it.
Words land because they appear in sentences you'd actually use — not because a graph says you're due in 14 hours.
Twelve
jungles.
Six free for B1–B2. Six premium for C1–C2.

Things
people ask.
Is my data sent anywhere?
No. Sage Ape is local-first. Your progress lives on your device. There is no account, no analytics SDK, no email collection. (Premium subscriptions are processed by the App Store or Google Play, which we never see.)
Does the Android version cost the same?
Yes — feature parity, same price. Sage Ape is on the App Store and Google Play, and a subscription bought on one platform is billed by that platform's store.
What level is Sage Ape for?
B1 to C2. The free decks cover B1-B2 vocabulary in everyday contexts; the premium decks cover C1-C2 — the words you need for fluent professional speech, exam prep, and reading nuanced material.
Can I add my own cards?
Not yet. Sage Ape ships with curated decks because curation is the product. Custom decks are on the roadmap for v2.
What about the gorilla?
Sage as in wise, ape as in the one doing the remembering. Also: monkey see, monkey remember. The gorilla is the mascot because gorillas are quiet, deliberate, and absolutely will not forget.
