A new design!

Design, 8 November 2016

FromScratch 1.2.0: search and more

Apps, 17 October 2016

FromScratch, the autosaving note taking app I built, just got another update: it now has additional search and replace functionality. It continues to do great in terms of downloads, I’m very happy that this tool helps so many other people.



FromScratch is a cross-platform, simple but smart autosaving scratchpad.
