Yes, there’s a high chance our webapp works on the device if you’ve got an updated Chrome browser on your device. Goto https://groshapp.com and pick login from the menu.
Then login to Grosh and tap … top right in Chrome and pick “Add to homescreen”
If you tap the Grosh icon on the home screen, the app will start up without the browser header/footer and actually look very similar to the normal app, but there’s a few features not available in the webapp.
