SaifGauge: Kakeibo Budget

"How much can I still spend?" SaifGauge answers the moment you open it, with one balance gauge. Made for budgeting from payday to payday. No bank linking, no account sign-up, no external connections, no ads. Your data stays on your iPhone. Extra features are a one-time purchase, with no subscription. ONE GAUGE The main screen is one big "Remaining" gauge, plus a mini gauge per category and a simple pie chart. "Per day" shows what's left divided by the days remaining, today included. The gauge changes color as money runs low and shows "Over budget" if you go over. Projected balance (Pro) estimates what's left on your cycle end day at your current pace. BUILT FOR PAYDAY CYCLES • Paid on the 25th? Set the cycle end day to the 24th. End of month works too • Payday on a weekend? Start the period the Friday before or the Monday after (Pro), or keep it • Prefer weekly? Set "Period length" to 1 week or 2 weeks (Pro) and pick the start weekday. The current period keeps its start date; your budgets are prefilled, scaled by days, and you can edit them • Budgets are saved per period; past periods never change. Edits to "Budget per period" start next period, or tap "Apply to This Period" • Roll leftovers into the next period as a lump sum or add them to your daily budget (Pro). With rollover on, overspending carries over too • Recurring costs like rent and subscriptions post automatically (monthly, every 2, 3 or 6 months, or yearly) in the period with their payment day.
