Grest app

This has completely changed my sourdough game.

I’ve realized that 72% hydration is the sweet spot for me as a beginner — every loaf comes out perfect and consistent. The real key is having a very active starter. I feed mine twice a day.

Also, this app doesn’t charge anything, which I love. With my 7.5-quart Dutch oven, I bake a double loaf, and it fills the pot perfectly.

Loving this whole process and loving this app

Thanks for the review!

It’s great so far

I love the calculator vibe it has. It’s no frills but that’s why it appeals to me. Don’t forget to save your notes progress or you’ll lose them like I did! I wish there was a way to pay for it to avoid the ads on the bottom of the app though.

Response from developer

Thanks for the review! I'll reply again if I get around to an option for removing ads. Thanks for the feedback!

Great calculator

It seems to work great. My question is, are you able to print out your recipe? That would be very helpful, eliminating the need to take screenshots & paste together.

Response from developer

Thanks for the suggestion - you can now export recipes to PDF 😊

Seems great to me.

Some low ratings say the weight is off. I double checked 4 different hydrations and it was right on…some aside it was slow. On my iPad it’s instant response…it does exactly what I want…fast simple hydration calculator, also saves all this with you cook temp and times…

I like it much so far. I don’t see amy way to pay for no adds, is mu only issue, but that’s not big…

Great Idea Ruined By Greed

In principle this would be a great idea. Unfortunately all the ads, usually with videos, cause it to continuously lock up. It’s like running a 2023 game on Windows 95. Frustrating and useless.
