sudoTip

sudoTip is a fast, modern tip & split calculator that stays simple for quick checks and opens up power tools when you need them. Tip, split, save, and share—your way.

WHAT IT DOES
• One-tap basics: enter the amount, pick a preset, choose before-tax or after-tax, and (optionally) round up to the increment you like.
• Advanced splits: equal, by shares/portions, or Lead + Remainder (treat). Add per-person extras and keep totals balanced.
• Expense mode: skip the tip and generate clean totals for reimbursements.
• Clear breakdown: see shared base, extras, per-person totals, rounding, and effective tip %.
• Share in a tap: send a clean, human-readable summary that friends actually understand.

MAKE IT YOURS
• Custom tip presets and emoji labels, plus a default preset for faster checkout.
• Flexible rounding increments (eg. 25¢, 50%, $1.00)
• Personalized share messages: set your opening line and choose exactly what to include (total, tip %, tip amount, per-person, extras, rounding).
• Choose your default split mode, portion templates, treat settings, and more.

SAVE THE DETAILS
• Save entries with names, per-person totals, extras, and optional subtotal/tax context.
• Save places (with optional auto-fill from your recent location) and attach receipt photos.
• Browse your history, filter and drill into details, and view insights over time.
• Export a tidy PDF and preview with Quick Look.

Simple when you want it. Advanced when you need it. Fully customizable so it works the way you do.
