Description by Michael Karsten Written by the developer, not by AppBrain. Click to read.
I'm Michael, 51. After carrying over 100kg for 20 years, I started intermittent fasting and lost 13kg so far. Couldn't find an app that did what I needed, so I built FastForward while losing the weight.
This app tracks my fasting journey. Now it can track yours.
What You Get:
- Fasting Timer
Track 16:8, 18:6, 20:4 or create custom schedules. Start, pause, or end fasts with one tap. See exactly where you are in your fasting window with a simple circular timer.
Weight Tracking
Log your weight and watch the graph show your progress over weeks and months. Finally see if what you're doing is working.
- Water Tracking
Calculate how much water you should drink based on your body weight. Track daily intake with one tap.
- Calorie Calculator
Enter your stats once: age, height, weight, activity level. FastForward calculates your basal metabolic rate and daily calorie needs. Know exactly how many calories to save for 0.5kg, 1kg, 1.5kg, or 2kg weekly weight loss.
- Progress Photos
Take photos throughout your journey. Compare before and after. Watch your transformation over time.
- Fasting Insights
Understand what happens during your fast: digestion phase, fat adaptation, deep ketosis. Know what your body is doing hour by hour.
- Blog & Updates
- Read about my fasting journey, app development, wins, and failures. Real updates from someone actually using the app daily.
Why FastForward is Different:
Built by someone who uses it every single day. Every feature exists because I needed it for my own weight loss. No marketing team guessing what fasters want—just real tools that actually help.
Your data stays on your device. No accounts, no cloud, no tracking. Just you and your journey.
Everything works offline. Fast in the wilderness, on flights, anywhere.
Who This Is For:
- Starting intermittent fasting and need simple tracking
- Experienced faster wanting better tools
- Anyone tired of complicated apps with features you'll never use
- People who want to see their progress clearly
Start Your Journey:
- Download FastForward. Pick your fasting schedule. Hit start. That's it.
- Track your fasts, monitor your weight, stay hydrated, and see results.
- Simple tools. Real results. No nonsense.
"You're doing wonderfully—one step at a time."
