We develop transparent, science-backed intermittent fasting intelligence, habit tools, and nutrition guidance without restrictive crash diets or deceptive paywalls.
FastingTracker was created by FlashSoft OÜ, an independent mobile health technology studio headquartered in Tallinn, Estonia (European Union). We started with a clear observation: most commercial fasting apps hide simple timers behind aggressive recurring subscriptions, confusing users with unscientific pseudo-health claims.
Our mission is the exact opposite: to provide transparent, clinically grounded intermittent fasting tools and evidence-based nutrition science directly to everyday people. Over 5 million users on Android and iOS trust FastingTracker to time eating windows, understand biological fasting stages, and build long-term metabolic resilience.
Every protocol, calculator, and article published on FastingTracker is produced and audited under strict clinical standards.
Aly Owen holds a Master of Science in Nutritional Sciences and is a Certified Nutrition Specialist with over 8 years of clinical practice counseling individuals on metabolic flexibility, insulin sensitivity, and circadian fasting.
View Full Medical Profile →We cite primary peer-reviewed clinical research from institutions like PubMed, NIH, The Lancet, and Cell Metabolism. No miraculous claims—just verifiable human biology.
Your metabolic data is your personal property. We strictly follow EU GDPR standards and never monetize, sell, or trade sensitive biometric information with data brokers.
Core fasting tracking, circadian stages (Ketosis, Autophagy, Glycogen depletion), and key calculators remain fully functional and free without forced account registration.
Fasting is powerful, but not suitable for everyone. We publish clear medical disclaimers and safety guidance regarding contraindications, pregnancy, and medical conditions.
