Chapterly is a Progressive Web Application (PWA), which means you can download it to any device, but you won't find it in any app store.
Most browsers have an easy-to-find Download button, but a quick web search will give you specific instructions for your browser of choice. If you're using a mobile browser, the option can usually be found in the Share menu. For instance, on Safari, it is listed as 'Add to Home Screen.'
Download Chapterly to your desktop, laptop, tablet, and phone, and sync your projects across all your devices by having a stable internet connection or restoring connection before switching to a different device.
Wherever you are when inspiration strikes, Chapterly is always available!
