Response from developer

Thank you for the feedback! We're glad you're enjoying the ad-free fasting timer. The science content is based on published research, though we always encourage users to explore the sources and draw their own conclusions. Also, good news—manual adjustment of fasting start times is already available, and additional flexibility is something we're actively exploring.

Great

I really wanted a tool that wasn’t full of ads and unnecessary account details. This is perfect.
