WhoseTurn: Bills & Purchases

Whose turn is it to pay? Share household bills and track your groceries.

WhoseTurn combines two essential financial tools in one app: a transparent shared bill tracker for couples and roommates, and a private purchase log for your everyday personal spending.
— SHARED BILLS —
Create a dedicated space for rent, electricity, internet, or anything else you split with the people you live with. Simply generate a 6-character code and your partner can join the bill from their phone. Record payments as you make them, and WhoseTurn calculates exactly how much each person has contributed—no spreadsheets required.
• Know Whose Turn It Is: For recurring bills, the app tracks who is up next based on who has paid less. If your partner already paid this month, the next payment is assigned to you. Either of you can still pay out of turn, and WhoseTurn will automatically balance the count.
• Fixed or Variable Tracking: Choose Fixed Schedules for predictable expenses (like monthly rent), or Variable for pay-as-you-go utilities (like cooking gas or top-ups) that skip schedules and just track usage.
• Per-Person Totals: Instantly see clear breakdowns of exactly how much each member has contributed this month, all-time, or on a specific day.
• Live Payment History: Every payment your partner records syncs to your phone instantly. See who paid, when, how much, and any added notes without needing to refresh the app.
• Calendar View: Switch any bill to Calendar mode to visualize your payment history day-by-day across the month.
— PERSONAL PURCHASES —
Keep a secure, private log of your own shopping. Record each trip, itemize your purchases, and track where your money goes.
• Predict Your Cycles: WhoseTurn automatically identifies the products you buy repeatedly. It calculates your average interval between purchases and shows how long it has been since your last restock—helping you predict when you'll run out of essentials.
• Monthly Insights: Get automated summaries of your monthly spending totals, identify your highest-cost days, and view your most frequently purchased items.
• Visual Spending Calendar: Your purchases are grouped by day and visualized on a monthly calendar using spend intensity, so you can easily spot your most expensive weeks at a glance.
— CORE FEATURES —
• Multi-Currency Support: Record shared payments and personal purchases in any global currency. WhoseTurn converts your totals to your preferred currency using daily exchange rates.
• Real-Time Sync: When a partner joins a bill, records a payment, or updates their profile, your screen updates instantly in real-time.
• Account or Guest Mode: Create an account to sync your data securely across devices and share bills with a partner, or use Guest Mode to keep everything strictly local on one device.
