Lovely css themes as standard and ability to add your own. Improvement if possible: make the markdown keyboard similar to what you see in an app like bear notes, this would be slightly easier to use. ### 5/5 — Perfect app *2026-05-10, version 1.6.7* This is the best markdown app I have ever used! ### 5/5 — Un editor utilissimo e intuitivo *2026-05-08, version 1.6.7* One Markdown è uno degli editor Markdown più facili che abbia mai provato. E’ intuitivo, leggero e molto user-friendly. Io lo uso per creare o modificare file di contesto per l’AI e anche per prendere appunti. ### 3/5 — Мне не подошел *2026-05-07* - Стили по умолчанию довольно страшные. Любые другие стили и вообще любые настройки платно ### 5/5 — Great, simple and fast *2026-05-06, version 1.6.7* As a good product should be ### 5/5 — Excelente y sencilla *2026-05-06, version 1.6.7* Durante años usé Drafts, pero One superó mis expectativas: es sencilla, intuitiva y, a diferencia de otras, maneja las tablas en Markdown sin errores. Ideal para escribir y exportar a PDF sin complicaciones. Recomendada. ### 5/5 — Good *2026-05-04, version 1.6.7* Does what I need very well. ### 5/5 — Simple, no bloat *2026-05-01, version 1.6.5* It has every feature you’d expect with no extra annoying stuff like ads or subscriptions. Just opens directly into a new file with no popups. The table editor could be a bit better/simpler I guess but it’s good enough Love it ### 4/5 — Great - For a Free App *2026-04-25, version 1.6.5* ✅ One Markdown is a great-looking integrated viewer and editor. Free, but worth paying for. ⛔️ No Search/Find. Fixed width render. 🤮Changes sometimes get lost. Dual-view scroll gets un-synced. Links in PDF don’t work. ### 5/5 — Phenomenal App *2026-04-20* I use it mostly for desktop, but I am trying to get out for mobile right now. I’m a huge fan of this app because I really enjoy apps that specialize in one thing and do one thing really well. Typically for me to view a markdown file I had to use Notion or my IDE, and I’m just not a huge fan of Notion at all. It was a huge headache to have to use it all the time and so now that I can view my documents in One Markdown and just open them from my folder it’s very simple to use, it does exactly the job I need it to and nothing more. I really appreciate this app. ## Frequently asked questions about One Markdown ### What is One Markdown?
