Fast: Fasting in Faith

Fasting was never only about food. Pray over each fast, follow daily scripture, and walk the 40-Day Journey. Fast for your body — and your soul.

Fast for your body — and your soul.

Most fasting apps are just timers. Fast is different. It unites the physical and the spiritual: lose weight and build healthy habits, while drawing closer to God through the ancient practice of fasting.

FASTING WITH PURPOSE Set a prayer or intention over each fast and keep it in front of you while you fast. Your hunger becomes a reminder to pray — not just a number on a clock.

THE 40-DAY JOURNEY A guided 40-day walk of scripture, reflection, and fasting — following the road Jesus walked in the wilderness. Begin any time, and especially during Lent (Fast knows when Lent is). Each day brings a passage, a short reflection, and a prompt to carry into your fast.

SCRIPTURE, PRAYER & REFLECTION • A daily Bible verse on fasting, woven right into your day • A simple prayer and intention tracker • Reflect after each fast — how it felt, what you’re grateful for, what you prayed

FOR YOUR BODY, TOO • A clean fasting timer with multiple protocols (12:12, 16:8, 18:6, 20:4, OMAD), each shown as a 24-hour ring of fasting vs. eating time • Understand every stage of a fast — from fat-burning and ketosis to autophagy — explained in plain language (timings are general estimates, never medical fact) • Weight tracking, streaks, milestones, and goals — including multi-week challenges • Science-backed lessons on fasting and healthy habits

SAFE AND SUPPORTIVE Your health comes first. Fast includes a gentle safety check, never glorifies extreme fasting, and shows clear medical disclaimers. Fasting isn’t for everyone — please consult a healthcare professional.

FOR EVERYONE Fast is built for Christians who want to fast with intention — and it respectfully supports other faith traditions and a secular reflection mode, too. Choose your path in onboarding; change it any time.

PRIVATE BY DESIGN No account required. Your fasts, reflections, prayers, and weight stay on your device. We don’t have servers that collect your data.

Fast is for general wellness and education and is not medical advice.
