The Dario Blood Glucose Monitoring app also lets you chart more including carbohydrate intake, calories and insulin doses and the results can be shared with anyone such as your doctor or family. Moreover, the statistics tab generally gives you a summary for a day, or the last week (7 days), month (30 days), or 90 days. This summary tells you the number of readings you had, the highest or lowest reading and then breaks the data down by how many readings were in range, average or below and then by how many hypers or hypos you had based on your custom settings. You can also click the summary box to see all the readings that fall into that specific category.
