User reviews

Simple and Refreshing Experience 🍋✨

SourTime is a clean, easy-to-use app with a simple, pleasant interface. It's straightforward to navigate and feels smooth throughout. Overall, it's a convenient and enjoyable app that's easy to explore!

Response from developer

Thank you — "easy to explore" is exactly what I was after. Most of the work went into leaving things out; sourdough has enough variables without an app adding more. If you haven't come across it yet, the widget now shows what's due even when no timer is running. Happy baking!

Convenient

I never thought about it, but it makes perfect sense to have a special tracking app for this. All the steps and timers in order, instructions right there, and even history!

Response from developer

Thank you so much! Keeping every step, timer and your bake history in one place is exactly why I built SourTime. Happy baking!
