Long term review
I really like this app for its simplicity. I have diabetes so keeping track of blood sugar is a priority for me. I also use the blood pressure, heart rate, walking, weight, workouts, and sleep functions. I have used Vitalbook for over five years now and it gets better with each update. What I would like to see is a means to tag blood glucose results with a pre-meal, post-meal, fasting marker like a color or something to differentiate them. Also the meals tab is in Japanese and having a English option would really make this a five star app. For now, 4 stars but I highly recommend trying this app.
