FastingPals is the social fasting app, built around one idea: the hardest part of fasting is doing it alone. Start a fast on your own or bring friends along. Join a public fast or invite people with a private code, watch each other's progress live, and keep each other going with buddy chat inside every fast. FAST YOUR WAY • One-off fasts or recurring schedules like 16:8, 20:4 and OMAD, solo or with a group • Water only, water and coffee, zero calorie, dry or your own custom rules • Ramadan mode with prayer times for your city • A timer that walks you through 17 estimated fasting stages, with tips along the way STAY ACCOUNTABLE TOGETHER • Join challenges for fasting hours, streaks, breathwork, hydration and steps • Create your own challenge, public or private, for up to 500 people, and share it with a link • A community feed of real milestones with reactions, comments and @mentions • Fasting Chat, a live room for everyone fasting right now • Friends, direct messages and shareable profiles A COACH IN YOUR CORNER Pick from eight coaching personalities, from a drill sergeant to a zen guide, a comedian or a scientist, with more to unlock. Your coach checks in as the hours pass and celebrates every milestone. BEAT CRAVINGS WITH GAMES Play live with your fasting crew: Pictionary, Chess, Connect Four, Fast Stack, Trivia, Fasted Hangman and a Dice Game. Or warm up with daily puzzles and arcade games, each with its own leaderboard. MORE THAN A TIMER • Breathwork: 10 guided techniques including Box Breathing, 4-7-8 and Wim Hof, solo or in a group session • Soundscapes: mix 30 calming sounds with a sleep timer • Clean Streaks: quit a habit with a live clean timer or build one with daily check-ins • Hunger Check-In: tell real hunger from a passing craving • Water tracking with a daily goal and reminders • Weight tracking with BMI, BMR and TDEE • Cycle tracker with period, ovulation and fertile window predictions, kept private • Step tracking during your fasts SEE YOUR PROGRESS Analytics show your total hours, streaks, longest fasts, trends, heatmaps and fasting schedule over 7 days, 30 days or all time, and you can export your history as a CSV file. MAKE IT YOURS Earn points for fasting, milestones, breathwork and games, with extra for public fasts. Spend them on themes, timer faces, ring shapes, coaches and titles, and collect 86 badges along the way. LEARN AS YOU GO Free, practical guides on getting started, the science of fasting, hydration, exercise, mindset and safety. PRIVATE WHEN YOU WANT IT Hide your stats, keep your profile friends-only or stay out of search and participant lists. Block anyone at any time. Habit slips and your cycle data are never shared. YOU CONTROL YOUR NOTIFICATIONS Choose exactly which alerts you get, set quiet hours, and tap any notification to jump straight to the right screen. Add a home screen widget to see your fast at a glance. ACTIVITY AND MOTION DATA Optional step tracking uses your device's motion data to count daily steps and estimate distance and calories burned. It's used only to show your activity in the app and how it lines up with your fasting. HEALTH FIRST FastingPals is for general wellness and education, not medical advice. Fasting isn't right for everyone. Talk to a healthcare professional before fasting, especially if you're pregnant, have a medical condition or take medication, and stop if you feel unwell. Whether you're new to fasting or building on a routine you already have, FastingPals gives you the tools, the community and the motivation to stay consistent.
