About HeliBoard
HeliBoard is a privacy-conscious open-source keyboard, based on AOSP / OpenBoard.
Does not use internet permission, and thus is 100% offline.
Features:
- Add dictionaries for suggestions and spell check
- build your own, or get them here, or in the experimental section (quality may vary)
- additional dictionaries for emojis or scientific symbols can be used to provide suggestions (similar to "emoji search")
- note that for Korean layouts, suggestions only work using this dictionary, the tools in the dictionary repository are not able to create working dictionaries

- can follow the system's day/night setting on Android 10+ (and on some versions of Android 9)
- can follow dynamic colors for Android 12+
- Customize keyboard layouts (only available when disabling use system languages)
- Customize special layouts, like symbols, number, or functional key layout
- Multilingual typing
- Glide typing (only with closed source library ☹️)
