This is also the formulating app that I have been using for some months already
Its probably the best app out there, and its free. Yes, better than all the paid ones
So I would recommend it to everyone, specially if you still do everything manually or with some excel table
By the way, I'm obsessed with the texture that professional machines accomplish. Its just insane the difference on what I get with my home machine
I've been trying to improve both the flavor and the texture a lot, trying all kind of methods, from the mixing of ingredients, to pasteurization, to the cooldown, aging, homogenization, churning and freezing.
With professional machines its kinda irrelevant how you do those steps, the important thing is to do them, and the result is amazing
But with home made machines, every single adjustment you make, changes a lot in the result, specially because machines are really underpowered, both in churning speed and strength, and in freezing power
