e-GuestList Check-In App

Jan 21, 2020

- Target SDK 28 (Android 9 Pie)
The min sdk version is always 4.2 (Jelly bean) so the app runs perfectly well on very “old” tablets too
- Upgrade of all libraries
- More than 10x faster data transfer from the server to the app.
New events even with tens of thousands of guests/attendees, are now uploaded to the app much faster
