I ran into a handy phone app today and I thought others might find it useful. It’s called Birth Planner. It’s an Android app (might be on iPhone too, I don’t know).
This app calculates the due dates for pigs and cows. Don’t expect any more of it. For my money (it was free), it’s more than worth it.
I don’t have trouble calculating due dates, but I don’t remember them very well. I get questioned about when litters will be born or weaned and it’s embarrassing not having an answer. I’ve documented this stuff online but I don’t always have Internet when I’m asked.
I almost always have my phone on me.
Enjoy!
