See what next month's bills will cost - from your own history, with math you can check. No AI, no account, no tracking. Works fully offline. Pro unlocks a 12-month view. Most bill apps only record what you already paid. Bill Forecast tells you what's coming. It reads your own billing history and projects next month's amount for every category - electricity, water, gas, internet, dues, phone, subscriptions or anything you define. Every number is produced by transparent, deterministic math you can inspect. No AI. No black box. WHAT YOU GET • Next-month forecast per category, with a confidence score • A change indicator that shows whether you're trending up or down • An accuracy score, so you can see how well past forecasts held up • A clear chart of your history plus the projected month • Import years of history from CSV or Excel in seconds - or add bills by hand • Records list with edit, delete and category filtering HOW THE FORECAST WORKS If the same month exists in a previous year, that month becomes the baseline - so seasonality is respected (winter gas, summer electricity). If it doesn't, a weighted average of your last three months is used. A capped year-over-year trend is then applied. The confidence score comes from how stable your history is, and every forecast carries a plain-language explanation of how it was calculated. BUILT FOR PRIVACY • No account. No password.
