## Description

The simplest one-stop shop for clinical RDs.

Designed by the experienced RDs at Stanford Hospital and Santa Clara Valley Medical Center to bring all nutrition support needs into the palm of your hand. Easily saves 10+ minutes per patient -- seriously, an RD's best friend.

Based on daily routines across all types of patients, we jammed EVERYTHING we need into just 3 simple screens. We've thoroughly tested the app in our own daily routines over the past year, and can't imagine not having this app anymore.

We've double-checked calculations many times and automated everything including tube feeding formulas where possible, so you don't have to. 

Screen 1: Quick Nutrition Needs --
Quickly determine BMI, IBW, kcal needs (both MSJ and Penn State, for on or off ventilation), and protein needs. Easily account for stress factor and protein multipliers.

Screen 2: Instant Tube Feeds --
Determine total volume, kcal, gm protein, %kcal protein, gm CHO, %kcal CHO, and mL free H2O in literally seconds. 

Screen 3: Parental Nutrition (TPN) calculator --
Input rate and duration, and either grams or percentage dextrose/amino acids/lipids to determine total volume, kcal, gm protein, gm CHO, GIR, and gm fat/kg. Works for both 2-in-1 and 3-in-1 methods.

We made this app to fulfill our own biggest painpoints, but after realizing how indispensable it's become to us, we hope it's helpful for others now too.

## Review summary

Users praise the app for saving time, ease of use, and having all key calculators in one mobile tool for RD workflows. The main drawbacks are data accuracy and outdated formulary content, with several reviews calling for more frequent updates to align with current product formulations.

### Pros

- Time-saving and fast calculations for energy, protein needs, tube feeds, and TPN.
- Very user-friendly and well-suited for on-the-go rounds; a comprehensive calculator in one app.
- Built-in formulary for quick comparisons between different tube feeds.
- Versatile workflows enabled (MSJ/Penn State, kcal/kg, adjustable TF duration/hours) to support RD decisions.

### Cons

- Formula data can be inaccurate or outdated; multiple reviews note miscalculations for Nutren 1.5, Jevity 1.5, Kate Farm variants and overall data not aligning with manufacturer panels.
- Updates lag behind new products and formulations; users request more frequent data updates to reflect Nestle/Kate Farm changes.
