Multi-platform
This app is where ever you are. Your phone, tablet, desktop, laptop, this program can be installed and run, not simply a website-in-a-box, but instead using native client side technologies to provide the best experience possible.
Offline first
I was frustrated with most of the story writing software I was finding as they were using web technologies (aka: Web Page in a box) which always seems to run into problems while being used offline for long periods of time. Hammer is designed from the ground up to be entirely local, no internet connection required, ever.
Transparent Data
Your data is yours. It's not stored in the cloud, or some opaque database. It is stored in simple, human readable files, just using files and folders to define the project structure. You can open your OSes file browser and take a look for your self. If this program went away today you would be able to easily interact with your data.
Intelligent Syncing between devices
Your data can be synchronized between devices allowing you to work on your story from anywhere, and have no fear of a change on one device, overwriting a change on another device.
Optional and Self hosted Syncing
Syncing is entirely optional, you can install the client and use it on one device, or you can install the server and sync your data between devices.
WhatsNew:
Hammer is out of beta!
- Server improvements:
+ Added Community features
+ Added About Page
+ Added Password reset system
+ Security hardening
+ Improved SSL cert handling
- Client: Added sync server info dialog
- Build improvements
While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device. Some clients have this repo enabled by default, e.g. Neo Store, Droid-ify, or, of course, the IzzyOnDroid client by Sunil. With others (like the official client) you'll have to add this repo manually (see the hint on top of the package list for how to do that).
