Hi everyone, I made an Android app that uses LanguageTool's awesome API to check your texts for errors. I thought I should share the app here on the forum. The app is named GrammarPal and is available on the Play Store. If you have suggestions on how to improve the app, please let me know.
Also, I have about 30 unlock codes to give to anyone who wants to use the premium features in the app. If you're interested, please let me know and I will send you one. The premium upgrade lets you undo changes, backup and restore your dictionary and some other app customizations. The core error checking is free.
