Simple apps for a first book, and the one habit that matters more than the app.

Writing a Book on Your Phone
Answer in brief
Write in an app that saves to the cloud as you type, like Google Docs or AxiomStory, so a lost phone never loses a chapter. Scrivener's iPhone app is the best choice if you also write in Scrivener on a computer.
AxiomStory publishes this reference. The pick reflects the criteria on this page. It is not a measured ranking of every tool.
Make it easy to start
Short sessions add up. Keep the app on your home screen, open it to the last line you wrote, and aim for 200 words, not a chapter.
Apps that work well
| Tool | Best for | Works on | Pricing |
|---|---|---|---|
| Google Docs | Free drafting and sharing with readers | Browser, phone apps | Free |
| AxiomStory | Long books with many characters, catching plot holes | Browser | Free to start, plans from $20 a month |
| Scrivener | Offline drafting and research | Mac, Windows, iPhone and iPad | One time purchase |
Don't lose work
Turn on sync before you start, and check once that a sentence typed on the phone shows up on your computer. Avoid apps that only save to the phone.
