Say goodbye to traditional weight tracking. LeanLine is a beautiful, private weight log designed to keep you motivated through daily streaks, progress insights, and Squad-based accountability.
== 100% PRIVATE BY DESIGN ==
Your actual weight is stored locally on your device. Your raw data never leaves your device. When you join a Squad or compete with friends, LeanLine only shares your relative progress, like “lost 1.5%”, keeping your absolute numbers completely hidden.
== BUILD YOUR STREAK ==
Consistency is everything. Log your weight daily, watch your flame grow, and build unstoppable momentum one check-in at a time.
== SQUADS FOR GROUP MOTIVATION ==
Create or join a Squad to make progress together. Whether you are tracking with friends, family, coworkers, or a weight-loss group, Squads help everyone stay accountable while keeping personal weight numbers private.
== HAVE FUN WITH FRIENDS ==
Fitness is better together. Invite friends securely, send nudges, track leaderboard scores, and hit your goals as a team without ever feeling self-conscious.
== SHARE STUDIO ==
Generate beautiful, custom-styled cards of your milestones and streaks, perfect for sharing your wins on social media.
== 100% AD-FREE ==
Focus completely on your fitness journey without any annoying banners, pop-ups, or interruptions.
