About this app

Thermatek prints race-kit labels on Bluetooth thermal label printers — fast, offline and exactly as previewed.

Each label shows a top line (like "T-Shirt(XXL)"), a scannable Code 128 barcode and the runner's BIB number, ready to stick on kit bags and T-shirt packs.

SERIAL PRINTING
• Enter a start and end BIB and print the whole range in one go
• Skip BIBs you don't need: 26505, 26510, 26520-26525
• Set your own top line, such as your event or brand name

LIST PRINTING
• Paste a JSON list of BIBs with T-shirt type and size
• Each label prints as "T-Shirt(XXL)", barcode and BIB
• Handles trailing commas and smart quotes, so copy-paste just works

BUILT FOR EVENT DAY
• Live preview: what you see is exactly what prints
• Print one label or the whole batch
• Progress bar with Cancel, and Resume if the printer disconnects
• Remembers your printer and reconnects automatically
• Works fully offline

PRINTER SETTINGS
• Any label size (default 38 × 25 mm) and gap
• 203 or 300 dpi printers
• Rotate 180° and multiple copies per label

Works with Bluetooth thermal label printers that support TSPL commands. On Android, pair the printer in Bluetooth settings first.

No accounts, no ads, no tracking. Everything stays on your device.
