Gratuity Lab: Tip Calculator

Know what you’re tipping on. Gratuity Lab brings receipt scanning, amount verification and bill splitting into one clear workflow. SCAN, THEN CHECK • Scan with the camera or choose receipt photos. • Recognize text on your device. • Compare detected amounts with the original receipt and zoom in on the evidence. • Review uncertain values and detected charges before using the numbers. • Try a sample receipt without camera or photo access. SPLIT WITH CONFIDENCE • Choose pre-tax or after-tax tipping. • Use custom percentages or your own quick-tip presets. • Divide a bill among up to 100 people. • See how any remaining cents are allocated when equal shares do not add up exactly. • Keep exact amounts or round the total or each person’s share. KEEP THE DETAILS • Save bills and receipt images in local history. • Search by merchant, add notes and reopen a calculation. • Share a calculation summary. READY FOR YOUR ROUTINE Choose currencies and regional number formats. Use light or dark appearance on iPhone and iPad. The interface is available in 11 languages. No account is required. Calculations, receipt recognition and saved history work on your device. Recognition results should always be checked against the receipt. Detected service charges and included gratuities are shown for review and are not automatically added to your tip calculation.
