If you do not have data access (wifi or cellular) in the gym or stadium where you are conducting the tournament, there is a workaround for that too. You can enable offline mode in ScoreTally and you will be able to do the score updates even without access to the database server.

Notes for Offline mode:

1. You have to enable offline mode while you have data access, preferably wifi. When you enable offline mode, data from database server will be downloaded to your phone and cached.
2. Enable offline mode only on one device and use this as the master device to enter the scores. If you have multiple devices with offline mode enabled, then there is a high probability for data conflicts. Local caches of data on different devices could differ leading to bad data to be written into the database server when the data access is back.
