Flux: Daily Budget & Savings

Learn to manage your money

Expected Nov 17, 2026 · Free · Designed for iPad. Not verified for macOS.

Two minutes a day with Flo: your daily budget, a short lesson, and progress that never resets to zero. Free, no ads, no bank connection. Anyone can learn to manage money. With Flux, two minutes a day is enough. Every morning, Flux tells you how much you can spend today: what's left once your fixed bills and savings are set aside, spread until payday. You log an expense in two taps. A short lesson teaches you something useful. And Flo, a little water drop, cheers every bit of progress and never lectures you. Flux is a free budget app, with no ads, and it never connects to your bank. YOUR PATH: A TWO-MINUTE LESSON A DAY 14 short lessons in four parts: know where your money goes, make it to the end of the month, your cushion, the expensive moments. Fixed bills, forgotten subscriptions, buy now pay later, sales, the holidays: one idea at a time. Each lesson ends with a question, with no grade and no penalty, then one action in your own budget. Flo comments, you decide. A GAME THAT HELPS YOU STICK WITH IT • Your ring: the days you stay under your daily budget, until payday. • A daily streak, with freezes and a vacation pause: never any guilt. • Your days under budget add up from day one. That total never goes back to zero, even after a slip. • Your records and your safety cushion, counted in days: real progress, not points. • Flo grows with you. Every pay period you finish in the green, he brings back a surprise: an accessory or a little find. • A card of your month to share, without ever showing your income or your spending. FLO, YOUR MASCOT Flo is a little water drop who follows your budget with you. He cheers when you save, worries before an overdraft and dozes off if you forget him. He reacts to your spending too, always kindly. FLO ON YOUR HOME SCREEN Add the widget, on your Home Screen or Lock Screen: your daily budget at a glance, and Flo changing through the day. Tap "Nothing spent" or your morning coffee: it's logged, without opening the app. He wakes up in the morning, nudges you in the evening, and beams once your day is logged. THE FASTEST WAY TO LOG • Type the amount, tap the category: done. • Your usuals (morning coffee, Saturday groceries) are added in one tap. • Type "12 lunch yesterday": Flux understands the amount, the label and the date. FLO LEARNS FROM YOU The more you log, the better Flo knows you. Fix a category once: he remembers it from then on. He also learns the days you spend the most, and your daily budget follows. In "What Flo knows about you", you see everything he has learned. And it all stays on your iPhone. YOUR SAVINGS POTS Vacation, safety cushion, new phone: set a goal and a monthly amount. Flo reserves it in your daily budget and tells you when you will get there. YOUR CHECKING ACCOUNT Enter your balance: Flux forecasts the end of your month and your upcoming bills, and warns you before you go into the red. STATEMENT IMPORT Import your bank's CSV statement. Flux spots your fixed bills and sorts everything by category. YOUR DATA STAYS YOURS No account, no email, no bank connection. Your budget data stays on your phone. No ads, no tracking, no data sold. You can lock Flux with Face ID or Touch ID, and export everything at any time. WHO IS IT FOR? If you often hit your overdraft around the 20th, if you've already given up on a budget spreadsheet after two weeks, or if nobody ever really taught you how to budget, Flux is made for that. Budgeting or saving, it all starts from one number: what you can spend today. FREE, FOREVER The daily budget, logging, the lessons, the game, reminders, import and export are free, forever.
