Mofu is a cute Pomodoro study timer with a pet who keeps you company. Set a focus timer for studying, reading, or work, and every session you finish becomes a little journey with your pet, with cozy campsites and keepsakes to collect. Look back on your focus time in Statistics. Available on iPhone and iPad. Choose a pet and a campsite, set your focus goal, and start. Your campsite shapes the scene for that session. When you finish, your companion returns with a discovery that makes your time feel worth remembering. With Mofu, you can: • Focus somewhere cozy. Travel through 10 themed campsites, each with its own scene and collection. • Collect memories from finished sessions. While your current collection still has souvenirs to find, each successful focus goal brings back one new souvenir, with a chance to discover a rare treasure. Revisit your finds and progress in the Journey Book. • Find a rhythm that fits. Use Normal Mode or choose Flow Mode when you want to focus without a fixed end time. Mofu Pro also unlocks Strict and Whitelist Modes to help reduce distractions. Add ambient sounds to set the mood. • See how your time adds up. Explore your focus rhythm in Statistics and Timeline; advanced insights and full history require Mofu Pro. Then visit your pets in Pasture. • Keep focus close.
