Can't find it anywhere on the android playstore? Has it been taken down?
It was taken down a number of months ago aswell. Hopefully it's gone for good we don't need two apps TFI and DB apps now GAI are up and running.
If an App is not updated in a certain timeframe it is automatically removed from the store in certain circumstances - that is what happened a couple of months ago so I guess it may have happened again.
Looks like there's nobody in house keeping DB Infra ticking over.
