No Tipflation: Tip Calculator

Tipflation is real. The minimum tip on Square checkouts went from 15% to 25% in three years, and now your sandwich shop wants 20% for handing you a bag. Worse, restaurants are quietly adding "service fees", "kitchen appreciation", "wellness surcharge", and auto-gratuity directly to the bill — so you end up tipping twice on the same dinner.

No Tipflation is the tip calculator that puts you back in control. It calculates your tip on the PRE-TAX subtotal, catches the hidden service charges most apps ignore, and warns you before you double-tip.

WHY PRE-TAX TIPPING?
The waiter didn't cook your sales tax. Why are you tipping on it?

On a $100 dinner with 8.875% sales tax, tipping 20% on the post-tax total costs you $1.78 more than tipping pre-tax. Multiply that across every dinner, every year. That's the quiet math No Tipflation puts in your pocket.

THE HIDDEN-FEE CATCHER
We detect 30+ kinds of charges restaurants now bake into the bill: service charge, mandatory gratuity, auto-gratuity, kitchen fee, wellness surcharge, living wage, equity fee, healthcare surcharge, "% Fee" patterns, admin fee, hospitality fee, and the long tail of regional surcharges. When your receipt already includes gratuity, a bold "Already tipped" warning lands on the result — so you don't pay twice for the same service.

WHAT IT DOES
• Calculates tip on the pre-tax subtotal (the whole point)
• Quick 12% / 15% / 20% buttons + custom percentage
• Splits the bill 1–20 ways, evenly
• Built-in receipt scanner — live preview plus tap-to-capture for crisper photos
• Receipt math validation — flags OCR mistakes and suggests one-tap fixes when subtotal + tax + service ≠ total
• Detects post-tax tip prompts on most major POS systems and warns you
• "Already charged a service fee?" disclosure to manually mark a fee the OCR missed
• Home screen widget for one-tap access
• Remembers your preferred tip percentage
• Works fully offline — your data never leaves your phone
• Share your tip math as an image — the receipt photo, your numbers, and the "tip on subtotal, not tax" reminder, in one shareable card
