About this app
Ready to stop guessing when you last ate? Fasting Mastery has you covered.
Pick your fasting program — 16:8, 18:6, 20:4, 23:1, or roll your own — and watch a live doughnut fill up as your fast progresses. Every second counts, and Fasting Mastery counts every one of them. Your current fasting phase (Fed → Metabolic Shift → Ketosis → Autophagy) is always front and center, with the details to back it up.
🍽 LOG IT IN SECONDS
Tap the button, pick a time (Now, 15 min ago, whenever), add calories if you feel like it, choose your meal type, and you're done. No friction. No fluff.
🍺 YES, ALCOHOL COUNTS TOO
Log a beer, a glass of wine, a cocktail — choose from 11 drink types, set your serving size and ABV, and Fasting Mastery does the calorie math for you. Because pretending that glass of rosé didn't happen isn't a fasting strategy.
📅 HISTORY THAT ACTUALLY TELLS A STORY
Every day gets its own visual card: a 24-hour timeline bar showing when you were fasting (blue) and eating (amber), plus entry chips with emoji, times, calories, and meal types at a glance.
📊 INSIGHTS THAT MAKE YOU FEEL SMART
• Auto-detected fasting pattern with a program comparison gauge
• Eating-window timeline so you can see your habits at a glance
• Streaks, personal bests, and week-over-week trends
• Calorie breakdown chart by meal type — with your BMR as a reference line if you set up your body profile
📈 THREE WAYS TO CHART YOUR WINS
• Timeline — see your fasting phases laid out across the day, every day
• Windows — fasting vs eating gaps with duration labels
• Bars — stacked phase time by day, month, or year
⚙️ THE DETAILS NERDS WILL LOVE
Set your country's standard drink definition (AU, UK, US, CA, JP, or custom). Enter your body stats for a resting calorie estimate. Sync everything to the cloud with Google sign-in (Pro).
No ads. No nonsense. Works offline. Your data is yours.
Start your fast. Master it.
