## What is TPN and Tube Feeding?

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. 

Feedback from clinical RDs is welcome! Just tweet us @NutricalcApp

### 5/5 — Please add to formulary

*2026-03-24, version 2.6*

I love this app, it’s very useful. Requesting for update the formulary to include impact peptide 1.5 and Kate farm standard 1.0, 1.5 and Kate farm peptide 1.0, 2.5. 

Also please consider making a pedi version, that would be amazing! 

Thanks!

### 5/5 — Best phone app for a RD

*2025-03-14, version 2.6*

There is no other app like this, at least for mobile. This is also well-made and easy to use. It saved me countless hours of time throughout my career and continues to do so. The main benefit is you can use this on the go or during rounds etc. without the need to go to a computer or website to use a similar app that isn't as well made or easy to use. The only downside is it doesn't provide every aspect of a tube feeding like vitamin or mineral content. It also is only on iOS so any interns with android won't be able to get it. Regardless, this app is worth it and you should get it especially if you're a clinical dietitian.

### 5/5 — Excellent app

*2024-12-28, version 2.6*

This is a fantastic app. I use it daily and it saves me so much time !

### 5/5 — Use daily

*2023-11-08, version 2.6*

I use this app almost everyday. Super helpful, especially for making recs on the fly. Would love to see an update to this app though!

### 4/5 — Needs Katefarms

*2023-10-04, version 2.6*

Super helpful when you’re seeing a ton of patients and need some quick math. Needs katefarms added!!!

### 1/5 — Incorrect

*2022-07-18, version 2.6*

Jevity 1.5 and Glucerna 1.5 not accurate with protein, free fluid.  Also TPN calculator not correct.

### 3/5 — Formula nutrient provision needs updating.

*2021-11-04, version 2.6*

Good app, but many Nestle formulas have changed slightly and the app has not been updated accordingly. 

Also, only way to contact developer is on Facebook, for which I do not have an account.

### 5/5 — Great app for clinical RDs

*2020-11-11, version 2.6*

Love this app! So easy to use and helpful for fast calculations of est energy/PRO needs and TFs. Highly recommend

### 5/5 — Please update

*2020-07-31, version 2.6*

Absolutely love this app. Please update the tube feeding choices to be more inclusive of the newer options.

### 1/5 — Miscalculates tube feeding nutrition

*2018-10-16, version 2.6*

Be wary of the data you are getting from this app! I have been using this app for sometime and just recently discovered it has the incorrect data for the formula Nutren 1.5 when compared directly with the Nestle nutrition panel information.
