Meet Mosskip, your reluctant fitness buddy. Turn everyday steps into XP, grow your companion, and build healthier weeks — without the pressure. Fitness apps can be a lot. Grumble isn’t. Meet Mosskip — your reluctant fitness buddy who turns everyday movement into progress. Walk, complete activities and build healthier weeks while your companion earns XP, develops new strengths and slowly evolves alongside you. MOVE WITHOUT THE PRESSURE Grumble rewards consistency rather than perfection. A short walk still counts. A recovery day still belongs in your week. There are no intimidating leaderboards or aggressive reminders—just a slightly grumpy companion waiting for you to move together. FEATURES • Track your daily steps and progress toward your goal • Sync step data from Apple Health with your permission • Create a flexible weekly movement plan • Log activities such as running, yoga, HIIT and more • Earn XP through everyday movement • Grow Mosskip from a tiny Grumpling into new evolution stages • See how your activity shapes Stamina, Strength, Vitality and Suppleness • Follow streaks, distance, calories and daily progress • Receive encouraging—and occasionally questionable—advice from Coach Mosskip YOUR MOVEMENT TAKES SHAPE The way you move influences the companion Mosskip becomes. Walk more, mix up your activities and watch Mosskip’s abilities develop across the week. Grumble is made for people who want to be more active without turning fitness into another stressful obligation. Walk a little. Grow together.
