Everything you need.
Nothing you don't.
Jarr does one thing well — helps you save with intention, inside the app you already use every day.
Goal-based saving
Create up to 3 named savings goals on the free plan — each with a target amount, optional deadline, and real-time progress tracking. Goals are yours to name: "House deposit", "Flight home", "Emergency fund".
Log deposits in seconds
Send an amount in any format and Jarr understands. "AED 500", "£200", "1000" — it's logged instantly in the right currency. No forms, no tapping through screens. If you have multiple goals, just prefix with a number: "2 AED 500".
Multi-currency support
Set one primary currency and up to two secondary currencies. Every progress update shows your total in all three. Rates are pulled from ExchangeRate-API — no markup, no guesswork.
You can log individual deposits in any currency regardless of your defaults. Jarr converts at read time so your history is always accurate.
Save with a partner
Invite anyone on WhatsApp to share a goal — a spouse, flatmate, or friend. You both log deposits, see progress, and get milestone notifications. Each of you sees the total in your own primary currency.
Contribution breakdowns show exactly who has put in what — useful for split goals like a shared house deposit.
Milestone celebrations
Jarr cheers you on at 25%, 50%, 75%, and 100% of every goal. Small moments of recognition that keep you going when saving feels slow.
Undo a deposit
Made a mistake? Send "undo" within 24 hours to reverse your last deposit. Jarr soft-deletes it and notifies your partner if the goal is shared.
Goal management
Archive goals you've paused, mark them complete when you hit your target, or delete them entirely. Archived and completed goals are preserved in your history — viewable any time with "history".
Zero friction onboarding
No app store. No sign-up form. No email verification. Message Jarr on WhatsApp and you're set up in two minutes — name, currency, and first goal.
