JotJam opens in the browser on a phone, tablet or laptop and has three separate tools: Sketch pad: pencil, pen, marker and eraser on blank, dotted or squared paper. Stylus pressure works (Apple Pencil and other pressure pens), and once you use a pen, fingers only pan and zoom so you can rest your palm. Floor plans and drawings to scale: walls, lines, arcs, curves, dimensions and text that snap to the grid, ends, midpoints and 15° angles. Type a length (3600 + Enter = 3.6 m). 51 architecture symbols drawn at real size: doors, windows, stairs, furniture, people, trees, section hatches. Piano, guitar and drums: play from the computer keyboard or by touch, metronome with tap tempo, record up to 10 minutes, fix notes in a piano roll, export MIDI or WAV. No install and no account needed to start. Signing in with Google is only for saving to your account; saving (and the scale PDF / DXF and sheet-music exports) uses credits, and you get free credits every day you sign in. PNG, SVG, MIDI and WAV downloads of saved work are free. The interface is in 14 languages. https://getjotjam.com It's my project, so feedback is very welcome, especially on the floor plan tool on touch screens.   submitted by   /u/ShengyuStudio [link]   [comments]
