Your body changes.
We tell you exactly how.
Real-time alerts as your body moves through each fasting phase — so you understand what's happening inside.
Your body switches fuel sources
After 8 hours, your liver glycogen depletes and your body converts fat into ketones for energy. The metabolic shift that makes fasting effective.
FastLah alert: "Your body just switched to fat-burning mode. The char kway teow is gone — now it's your fat's turn."
Growth hormone surges up to 5×
At 12 hours, human growth hormone production spikes dramatically — preserving muscle mass, accelerating fat breakdown, and triggering cellular repair.
FastLah alert: "HGH is surging right now. Your muscles are being protected. Keep going lah!"
Your cells are cleaning themselves
At 16 hours, autophagy activates — your body's cellular recycling system breaks down damaged proteins and debris. Linked to cancer-cell elimination and longevity research.
FastLah alert: "Autophagy ON. Your cells are eating the junk inside them. Nobel Prize-winning science happening in your body."
Deep gut reset & immune renewal
At 24 hours, intestinal stem cells regenerate, immune system resets, and insulin sensitivity improves significantly. Your gut begins a full microbiome reset cycle.
FastLah alert: "24 hours done. You just completed a full cellular reset. Your gut is rebuilding. Incredible work."
Everything Zero has.
Plus everything it doesn't.

From our early adopters.
"Finally an app that knows what char kway teow is. The body science alerts are so motivating — the H16 autophagy notification made me never want to break a fast early again."
"FastLah Ramadan is something I didn't know I needed. The GPS-based Suhoor alarm has never once been wrong. The 30-day tracker kept me motivated across the full bulan Ramadan."
"Aplikasi puasa pertama yang benar-benar paham makanan Indonesia. Saya bisa log nasi goreng, rendang, bahkan martabak. Bayar pakai OVO juga gampang banget!"
