Poster & Calendar Maker — in-app screenshot

Design software and print prep,
in one app.

No Photoshop, no Canva subscription, no separate mockup tool. Drop in photos, lay them out, and export a file that’s already sized for print.

Two tools, one app
Poster Mode for single pieces, Calendar Mode for a full 13-page personalised calendar — cover plus all 12 months. Same layout tools, same drag-and-drop workflow, either way.
Poster Mode Calendar Mode
Built for print-on-demand
Every layout is sized correctly for Printful, Printify, Gelato and other major POD services from the start. Real-time DPI warnings mean you’ll never send a blurry file to print.
300 DPI export DPI warnings
AI upscaling, built in
Low-res photos still print sharp thanks to a bundled AI upscaler — no extra install required. Already have Topaz Photo AI or Gigapixel AI? The app detects it automatically.
