Review momentum
49/100
faster than 49% 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.

Latest updates
1.2
Added an option to rate Nicutools from Settings. You may occasionally be asked for a review after finishing a calculation.
1.1.1
Glucose Delivery: the Enteral figure in the result breakdown now includes any added carbohydrate, so IV + Enteral again matches the Total GIR shown above it. Calculations were always correct — this affected the breakdown display only.
