Buggy as hell. Lost more than 3 hours of writing.
A big deal is made in their description of the beauty and simplicity of their editor but until it works correctly it is more than useless - its a liability to your work.
I used the app for around 5 hours today. At the 2 hour mark I noticed things getting choppy and so I copy and pasted what I had written to notepad (which I will note the Medium app only lets you select one paragraph at a time so it is very difficult to make a copy/backup???).
To my own demise I continued to use the app to write for another 3 hours as I was on a roll and wanted to format as I went. Things continued to be a little choppy here and there with big delays in selecting text etc. Then the app crashed after 3 hours of writing. In reopening the app all that work was lost and the version that was saved to my drafts was probably at the half hour mark. Devastated. I am disabled and thus losing 3 hours work is beyond this. Do not use this app to write in. It is not safe to do so in its current state.
