Useful but could be better

I am a novice at home sous vide cooking. The app is pretty much self explanatory and gives useful information. Im a bit perplexed as to why frozen food cannot be the starting point in calculating cooking times as that would be very useful. Seems the physics would be pretty much the same so just knowing freezer temp is all that is missing. Easy enough to measure that but the app will only accept temps as low as 0C/32F so cannot get calculation for frozen food. Too bad.
