About this app

Print photos, notes, labels and PDFs to the Bluetooth mini printer you already own, at the right size, with a preview that shows exactly what will come out.

Thermly is a mini printer app for pocket thermal printers, receipt printers and portable A4 printers. One app for the printers people actually have, with no account and no ads.

WHAT YOU CAN PRINT
- Photos from your gallery, in black and white made for thermal paper
- PDF and document pages: pick the page, print it at the paper width or an exact size
- Notes and lists, with checkboxes for to-dos and shopping
- Labels with a QR code or a barcode, so your mini printer works as a label printer for jars, boxes, folders and shelves
- Banners that run down the strip, like today's date
- Anything shared to Thermly from another app: images, PDFs and text

THE PREVIEW IS THE PRINT
The preview is drawn at your printer's real dot width, in the same black and white the thermal printer burns, so what you see is what prints. Choose Photo for pictures, Text for sharp writing, or Line art for drawings and outlines. Rotate, adjust brightness and contrast, and print up to five copies.

THE RIGHT SIZE
Fit the paper, or set an exact width in centimeters or inches and Thermly prints it true to size. Long notes and lists print as one continuous strip.

PRINTERS THAT JUST CONNECT
Add a mini printer with Android's own pairing sheet: Thermly finds nearby printers without asking for your location. Printers already paired in Bluetooth settings are listed too. Thermly remembers your printers and the last one you used, and cat printers keep their darkness setting.

ALWAYS A WAY TO PRINT
If a printer is not on the list, print through Android's System print (Wi-Fi printers and Save as PDF), or send the page at the right size to the printer's own app.

TEMPLATES AND HISTORY
Start from a to-do list, a shopping list, a sticky note, a label, a QR code or a date banner. Every print is kept on your phone in History, ready to print again in a tap.

THERMAL PRINTERS IT WORKS WITH
Cat printers (GB01, GB02, GB03, GT01, MX05, MX06, MX08, MX09, MX10, MX11), Phomemo M02, M02S, M02 Pro and M08F, and 58 mm or 80 mm Bluetooth receipt printers.

8 LANGUAGES
English, German, Spanish, French, Italian, Japanese, Korean and Portuguese (Brazil).

PRIVATE BY DESIGN
No account and no sign-up. Your photos, notes and print history stay on your phone, and Thermly never uploads your prints. No location permission on any Android version.

SUBSCRIPTION
Your first 2 prints are included. After that, a subscription is required to keep using Thermly. Choose a weekly, monthly or annual plan; the annual plan starts with a 3-day trial. Plans renew automatically at the price shown until you cancel in Google Play. Cancel a trial before it ends and you won't be charged. Prices are always shown before you subscribe.

IMPORTANT
Thermly is an independent app and is not affiliated with Phomemo or any printer maker. Printer names describe compatibility only.
