Hey Product Hunt I built BillAlign because I was tired of doing the same math every month. My partner gets paid weekly, I get paid biweekly, and my side hustle pays monthly. Every month, the income date changes, but Rent is due the 1st, Car payment is due the 25th, Insurance is due the 5th, etc, the due dates never change. Every month, I would sit down and figure out which paycheck covers what, how much to carry forward, and whether we'd have enough before the next payday. Same exercise, every single month, because the dates shift. Every app I tried either reminded me when bills were due (not the problem) or asked me to connect my bank and categorize spending after the fact (also not the problem). The problem was the planning math before the money moves. So I built BillAlign. It assigns your bills to the right paychecks automatically, collapses 10–15 due dates into 2–4 payment windows, and recalculates everything when your pay dates shift next month. Just one-time setup, enter your income schedule and bills schedule. Open the app on payment day, pay what's listed, and close the app. Done. It also handles debt payments around real cash flow and drafts a plan to minimize interest paid. It's built in React Native, runs entirely on your device, no account needed, and just shipped on both the App Store and Google Play after about a year of nights and weekends around a full-time job. I'd genuinely love honest feedback, especially from anyone who's dealt with biweekly or irregular pay schedules. What would make this more useful for how you actually manage bills?
