You can download the Android app here.
Create rich notes, to-do lists, and documents using Markdown with this fully-featured text editor. Whils, using only half of the space required for a robust text editor, and works completely offline in the best interests of your privacy.
And if you’re afraid of losing your notes and want to use a VPS as another node for storing your notes but you’re also concerned about privacy, you can set that one up as an untrusted node, and the data will be encrypted at rest, on top of being encrypted during transit like usual.
