Fever downloads
Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.

How this is calculated

Review momentum
20/100
faster than 0% of Medical apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About Fever
Keep the overview of body temperature, medications and other events during an illness.
Note: Neither the iPhone/iPad nor this App is able to MEASURE the body temperature!
Particularly in winter you often come down with a cold. Sometimes the cold is attended with raised temperature – worst case with fever.
Not only a bad cold, also a number of other diseases come along with fever and need a quick treatment. Particularly children incline to fight against illnesses with fever.
If you go to the doctor, it is good to know the exact course of the fever, because according to fever pattern and other symptoms the doctor can diagnose faster.
Above all, if several members of the family are ill at the same time, you can keep the optimum overview with your fever diary.
With FEVER you grasp simply and intuitively:
∙ Temperature and fever measuring zones (mouth, ear, arm, forehead or rectal)
∙ Medication and dose (e.g. Paracetamol, 1 tablet)
∙ Events and condition (e.g. headaches, vomiting)
∙ Notes
Other features:
∙ Fever and illness adjustable for several people
∙ Easy representation of the temperature curve by means of graph
∙ Direct comparison to previous measurements (arrow and value)
∙ Directly representation of fever classification
∙ PDF & CSV Export
∙ Support for Celsius and Fahrenheit
Notes:
∙ This program is not a substitute for a doctor's visit! With fever a doctor needs always to be consulted!
∙ Neither the iPhone/iPad nor this App is able to MEASURE the body temperature! (e.g. Breathing 2 minutes into the microphone is neither usable nor precise)
