When did the first tooth come through? Which one came next, and did your little one have a fever at the time? Toothli is a baby tooth tracker that remembers your child's teething, so you don't have to. Tap the tooth that is coming through in the tooth chart and enter the date. That's all it takes. Tooth by tooth, you build a complete record of all twenty baby teeth, from the first incisor to the last molar. WHY PARENTS USE TOOTHLI • Have the answer ready when the pediatrician or dentist asks which tooth came when • See whether fever, fussiness or rough nights lined up with a tooth coming through • Keep track of siblings: every child gets their own tooth chart • Hold on to a memory that would otherwise fade within a few years TOOTH CHART • All twenty baby teeth in an anatomical chart of the upper and lower jaw • See at a glance which teeth are already in and which are still to come • Tap a tooth to see the date or your child's age when it came through RECORDS • Eruption date for every tooth • Loss date, for when the baby teeth fall out later on • Teething symptoms: fever, fussiness, drooling, red cheek, trouble sleeping • Your own notes on each tooth SEVERAL CHILDREN • As many children as you like, each with their own tooth chart and progress WIDGET • Shows on your Home Screen how many teeth are in and which one to expect next KEEPSAKE SHEET • A single page with the tooth chart, every date and the key figures: first tooth, last tooth, how long it took • As a PDF to print, add to the baby album or send to the grandparents ON ALL YOUR DEVICES • With iCloud, your records stay the same on your iPhone and iPad automatically • Save all your data to a file as well YOUR DATA STAYS WITH YOU No sign-up, no account. Your records live on your device and in your own iCloud. Toothli sends them neither to us nor to anyone else, and there is no server holding anything of yours. FREE Toothli is free and shows banner ads. On first launch you decide whether your data may be used for personalized ads. A one-time purchase removes the banners completely. Available in 40 languages. Good to know: the eruption ranges for each tooth are averages for guidance. Every child teethes at their own pace, and Toothli does not give a diagnosis.
