Weekli answers the only budgeting question that matters: how much can I spend this week? No spreadsheets. No bank syncing. No 47-tab setup process. Just set your weekly budget, log what you spend, and get on with your life. BUDGETING THAT TAKES SECONDS, NOT HOURS Tap, enter an amount, pick a category, done. Weekli is built for people who want control over their money without turning personal finance into a second job. Set budgets for groceries, fuel, entertainment, dining out, or whatever categories fit your life. Swipe between them to see exactly where you stand. Color-coded progress bars show your remaining budget at a glance. Green means you're cruising. Yellow means slow down. Red means trouble. You'll always know where you are without doing mental math. MEET PENNI Penni is a coin-shaped mascot who lives inside your budget. When you're saving well, Penni is thriving. When funds run low, Penni gets nervous. Blow through your budget entirely, and... well, Penni has seen better days. It sounds simple, and it is. But Penni turns dry numbers into something you actually feel. Watching your little coin friend celebrate a well-managed week is oddly satisfying, and seeing Penni struggle is the gentle nudge most people need to think twice before that impulse purchase. The weather changes too. Sunny skies when your budget is healthy, storms rolling in when things get tight. Your whole screen reflects how your week is going. WEEKLY ROLLOVER Had a great week and came in under budget? Weekli can roll your savings into next week, giving you a little extra breathing room. It's optional, simple, and rewarding. At the end of each week, you'll get a summary. Stayed on track? Penni celebrates with you. Went over? You'll get an honest look at what happened, so next week can be different. SEE YOUR PATTERNS The history view shows your spending as a day-by-day heatmap, making it easy to spot trends. Maybe you always overspend on Fridays. Maybe January is consistently tight. Weekli makes those patterns visible without charts that require a finance degree to read. PRIVACY IS NOT A FEATURE. IT'S THE ARCHITECTURE. Weekli never asks for your bank login. It never uploads your transactions to a server. There is no account to create and no cloud sync to worry about. Every number you enter stays on your device and nowhere else. ONE PRICE. NO SURPRISES. Weekli is a one-time purchase. No monthly fees, no annual subscriptions, no premium tier that locks away the features you actually need. Pay once and the app is yours, with every feature included and every future update covered. WEEKLI IS FOR YOU IF: - You tried YNAB or Mint and felt overwhelmed - You just want to know if you can afford dinner out this week - You hate connecting bank accounts to third-party apps - You want a budget tool that respects your data and your time Set your budget. Track your spending. Keep Penni alive.
