Gratuity — Tip Calculator

Gratuity is a tip calculator for restaurant and service bills. Target audience: general consumers eating out who want to quickly calculate a tip and split a bill among a group. It solves the "check just hit the table" moment — fast bill entry, tip %, and per-person split without digging for a system calculator or doing mental math. Free tier covers the full core flow; Pro is a one-time cosmetic/convenience unlock (themes, history, widget), not a functionality gate on the core calculator. FREE - Custom number pad that feels like a machine, not a form - Tip presets (15/18/20) or dial in any percentage - Split between up to 20 people — everyone pays the same, the math always adds up - Round up to the nearest dollar with one tap - Remembers your last-used tip and split PRO — one-time purchase, no subscription - Three more themes: Neon Arcade, Diner Receipt, Banker - Bill history, last 30 bills - Home Screen widget with your last bill Designed for the moment the check hits the table: slightly loud restaurant, friends waiting, no patience for menus. Open, type, done.
