Four apps in one. Your data stays yours.
Leo brings money, habits, tasks and notes into a single app — so the four small
things you meant to keep track of every day finally live in one place instead of
four.
WHAT LEO DOES
Money — Wallets, categories, transactions and a monthly summary. A balance is
always recomputed from your transactions rather than stored as a number, so it
cannot quietly drift out of true.
Habits — One tap to mark a day done. Skip a day without breaking the streak,
because some days genuinely should be skipped.
Tasks — Things with a deadline, things that repeat, things that can wait. With a
reminder when the time comes, and without a project board you never asked for.
Notes — Speak and it becomes a note. Leo keeps the words, not the sound.
SPEAK ONE SENTENCE
Say "spend 4.50 on breakfast from cash" and the expense form opens, already
filled in. Say "remind me to call the dentist tomorrow" and you get a task
instead. Say "make a note" and you get a note. No tab to pick first, no phrasing
to memorise.
Leo reads what you said and works out where it belongs — money, task, habit or
note. Then it opens the form and you press Save. Nothing is written into your
records on its own.
Vietnamese and English mixed inside one sentence is fine. That is how a lot of
people actually talk.
YOUR DATA STAYS YOURS
We run no server. Your records are stored on your own device and synced through
iCloud inside your own Apple account, in the private database only you can open.
• No account, no sign-in, no email address
• No ads, no tracking, no analytics
• No audio recording is kept
• Export everything to a readable JSON file, any time
• Delete means deleted
ABOUT THE AI
The AI features are optional and run on your own OpenAI key, kept in your device
Keychain. We ship no key of ours and take no share of what you spend.
Without a key, Leo still listens using Apple's on-device speech recognition, and
its built-in rule reader still turns what you said into the right form. Money,
habits, tasks and notes all work in full with no key at all.
When the AI reader does run, what leaves your device is one sentence — no
balances, no wallet names, no past transactions, no other notes.
ONE PURCHASE
Buy once and use it on your iPhone and iPad. No subscription, no in-app
purchases, nothing to renew.
Vietnamese and English throughout, switchable inside the app. Light and dark.
Ratings & Reviews
This app hasn’t received enough ratings or reviews to display an overview.
• Copy is back in notes, next to the microphone.
• The Share sheet on iPad now opens next to the Share button.
• Category and habit icons no longer repeat: every workout has its own icon.
