Bike Compatible Apps

Bike supports three file formats bike, opml, and txt as described in Using Documents. Each is what I would describe as an "open" file format, a format for structured data that is already supported by other applications.

The OPML format in particular is a common standard for outlines. If you want to share outlines with another app OPML is likely your best bet. Here is a list of OPML compatible apps on the opml.org website.

• Cloud Outliner (macOS + iOS) – Import and export OPML.

• Drummer (Web + Electron) – Uses OPML as native format. The Electron version saves OPML directly to disk so you can work on the same file with Bike and Drummer without import/export. Both the web and Electron versions support import and export of OPML. Copy and paste outlines with Bike.
