Brush the full two minutes, every time. Hippobrush guides each part of your mouth with a gentle tap, on your iPhone or right from your Apple Watch, and turns brushing into a streak you will want to keep. Most of us stop well before two minutes, the time dentists recommend. Hippobrush keeps time for you, tells you when to move to the next quarter of your mouth, and shows you where you have been. Then floss, rinse, and you are done. FREE FOR EVERYONE - A calm 2-minute brushing timer: four 30-second quadrants with a gentle tap at each change - A live mouth map that fills in as you brush - Apple Watch app: start from your wrist and feel each quadrant change, no phone needed - A daily streak with a freeze for the day life gets in the way, plus achievements - Morning and evening reminders, and a nudge when it is time for a new toothbrush - Home Screen and Lock Screen widgets, watch complications, and a Live Activity on the Dynamic Island - Brushes saved to Apple Health - Brush-buddy challenges: invite a friend and keep each other going - Haptic-only mode for a silent brush - Your first Smile Check HIPPOBRUSH PREMIUM - Floss and rinse timers, so your whole routine lives in one place - Brush to your music: pick a song or playlist, and it pauses when your time is up - Profiles for everyone at home, with Kid Mode: a mascot that reacts as your child brushes, and stickers to collect - A 30-day dentist report as a PDF, ready for your next visit - Your full history and detailed stats (free keeps the last 7 days) - Smart Coach: personal brushing insights and answers from Apple Intelligence, on your device - Unlimited Smile Checks - Mirror mode, custom durations, and custom reminder times SMILE CHECK Take a photo of your smile and get a quick, general look at how your teeth look, with a score you can follow over time and simple brushing tips.
