I'm Sarah, a designer from Austin who turned my intermittent fasting experiments into data art. 6 free tools to plan eating windows, analyze metabolism, and track trends — no guesswork, just numbers.
Everything I wish I had when I started my fasting journey in 2023. Each tool solves a specific problem I ran into.
Log start/end times, track streaks, see your consistency score. I use this every single day.
Estimate ketosis timing, autophagy windows, and metabolic switching based on your body data.
Smart scheduler that aligns your eating window with sleep, work, and workout times.
Visualize your fasting patterns over weeks and months. Spot the trends I almost missed.
Set fasting goals, get milestone predictions, and see exactly when you'll hit your targets.
Download your fasting data as PDF or CSV. Share with your doctor or keep for yourself.
Real experiments, real data, real mistakes. Follow along as I figure this out.
