About

Expense Tracker

Read full description

FullWallet is a personal finance app for people who want a clear answer to one question: how much can I actually spend? Every month starts with your income. FullWallet subtracts your fixed costs, your spending and what you have put aside, then shows what is genuinely left — updated the moment you add anything. TRACK IT IN SECONDS • Add income, expenses and savings in a couple of taps • Name and icon your own categories, and edit them whenever you like • See income against spending at a glance, and which categories take the most • Set a monthly limit on a category and hear about it before you run out FIXED COSTS THAT BEHAVE Rent, subscriptions, insurance — enter them once and they count every month on their own. They are never duplicated as expenses and never inflate your spending charts, so what you compare month to month actually means something. CARD PAYMENTS THAT LOG THEMSELVES Switch on automatic transactions and every card tap you make in a shop files itself — amount, merchant and a matching category — without you opening the app. A shop it does not recognise lands in Other; change it once and it stays changed. ADD BY VOICE Say “spent 45 euros on groceries” and FullWallet fills in the amount, the currency, the category and the name. It waits for you to finish talking instead of cutting you off mid-sentence. STRAIGHT FROM YOUR HOME SCREEN The widget shows what is available to spend and takes you straight into adding income, an expense, a saving, or a voice entry. Whichever button you tap, the app opens already doing it. AI MONEY COACH Once a month, get a plain-language read on where your money went: the one pattern worth acting on, and a few concrete things to try. BUILT FOR SAVING Track what you have set aside by month, by year, or across all time, and watch the total climb. WORKS THE WAY YOU DO • 73 currencies, with a currency per transaction and automatic conversion • 46 languages, with voice entry in 35 of them • Light and dark themes • Export everything to CSV, and import it back when you change phone YOUR NUMBERS STAY YOURS Your transactions live on your iPhone. There is no account to create and no sign-up, and individual transactions are never uploaded — running an AI analysis sends your monthly totals by category, nothing more. FULLWALLET PREMIUM Premium unlocks automatic card transactions, voice entry, and the monthly AI Money Coach. Everything else stays open to everyone: tracking, budgets, fixed costs, savings, the widget, and CSV export and import. • Lifetime — one payment, yours for good • Monthly, with a one-week trial to begin Payment is charged to your Apple ID at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours of the end of the period. Manage your subscriptions and turn off auto-renewal in your App Store account settings after purchase. Any unused portion of a trial period is forfeited when you buy a subscription.
