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 **Developer response:** Thanks for the review! ### 5/5 — It’s great so far *2025-01-23* 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. **Developer response:** Thanks for the review! I'll reply again if I get around to an option for removing ads. Thanks for the feedback! ### 5/5 — Great calculator *2024-11-11* 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. **Developer response:** Thanks for the suggestion - you can now export recipes to PDF 😊 ### 5/5 — Seems great to me. *2024-09-17* 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… **Developer response:** Thanks for the review! ### 1/5 — Great Idea Ruined By Greed *2023-12-29, version 1.5.0* 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. ### 1/5 — The add is in the way *2023-12-02* The add is placed so that you cannot see or use the app. **Developer response:** Could you please try the latest version? ### 1/5 — Wrong CALCULATION *2022-10-16* If you add the weight of flour, water and starter the final dough weight is so off 500-800g what kind of app is that hahah waste of time !! Garbage…used to be such a good app not any more **Developer response:** Can you please update the app - this issue has been resolved. Would appreciate an updated response here - thanks! ### 4/5 — Exactly what I was looking for *2022-06-23, version 1.3.0* This app is very easy to use - perfect to get ratios for bread in a flash. Why not 5 stars? well, it's the ads. It would be great if the developer provided an option for add-free for a small fee. Otherwise, congratulations to the developer for functional simplicity! ### 1/5 — Version 12 a backward step *2022-04-26, version 1.3.0* Just upgraded to version 12 on my iPad and it is very slow to respond. The sliders are static and the ads are a pain. Upgraded to v1.3 ... still very slow to respond. ### 3/5 — Only in Fahrenheit? *2022-04-21* I think the developer is missing out on the 7.5 billion who use Celsius. ## Frequently asked questions about Sourdough Hydration Calc ### What is Sourdough Hydration Calc used for?
