It’s all truly excellent. My main recommendations so far would be to make it easier to correct errors entered into height and weight measures (as I learned from a very prompt and clear customer service person named Toni, this can be done by swiping left on a given measurement, but this is not intuitive, so some kind of indication on that page would be helpful). Secondly, I recommend adding a similar measurement system for head circumference, since most doctor’s visits include that anyway, and is of higher importance in the age of Zika. Another, more challenging, issue is this: the statistics should be calibrated to take account of where children are relative to due date, not actual date of birth, so as to take into account preemies (and ‘posties’). There is a publicly available set of alternate statistics for preterm babies that can be used, as well as variant benchmarks used by CDC and WHO (TinybeansPrivateFamilyAlbum Growth+ includes two variants for each organization, plus the preterm variant). By using the actual date of birth rather than the estimated due date, the measurement percentiles used by the Tinybeans app end up being highly skewed toward babies born exactly at their due dates. This would seem a major area of opportunity in an otherwise highly evolved, sophisticated, and delightful app!
