I made a sourdough baking app!
It's called Rise and it was me and my friend's "pandemic project" over the past few months. It includes some recipes, makes planning easier, manages the schedule, allows sharing with friends, and tons more.
I've been baking sourdough for about 6 years and I'll say that even for a semi-experienced baker, it removes so much stress around scheduling. At a glance I can see every step of the process and keep myself from, say, scheduling the oven bake and a kid pickup at the same time ?. Another great feature is if you just tell it the temperature of your dough, it will set the bulk rise and proof times automatically based on the temp and the dough ingredients.
It's mostly free but there are some features/content only available with a purchase. However for launch, subscriptions are 50% off.
Currently it's iPad/iPhone only but if there's enough interest we'll try to build an Android version too.
Hope y'all find it useful!
