## What is Laminitis?

Laminitis®, the official Laminitis Risk® app, a Grazing Risk Monitoring Service provides horse owners with a practical tool to help monitor weather conditions in a way that can be used to warn when grazing on grass posses an increased risk to horses prone to laminitis.

Local weather conditions are monitored and used to predict the rise and fall of non-structural carbohydrates (NSCs) in C3 grasses and starch in C4 grasses. When the predicted levels of NSCs or starch increase, this is shown as a rise in risk.

Under extreme weather conditions grass can become stressed and in these circumstances significantly increase the risk of a horse becoming footy or suffering a laminitic episode. When this type of weather pattern happens the risk gauge will rapidly increase to High and maintain this level until the NSC and grass stress levels are predicted to have lowered again.

Today, laminitis is a major problem for horses worldwide and is one of the most common causes of lameness. With the help of this app as an educational tool, it is hoped that fewer horses will suffer from this condition in the future.

With the standard version of the Laminitis app, the one-time purchase grants you access to the core features:

• Quick & easy access to realtime monitoring of the risk level where you are
• Choice of using your current location (GPS) or use the built-in search to locate the place you would like to monitor
• Access to in-app educational information
 

For additional weather data and advanced features a single subscription grants you access to:

• Access NSC forecast levels up to 24 hours in advance to support better grazing safety decisions
• Laminitis Risk® notifications alerts and daily reminders
• Advanced weather analytics to estimate Fructan, Starch, Simple sugars and NSC levels
• Configurable temperature statistics (over 24hr period)
• Hourly UV levels and cloud cover
• Daylight hours: Sunrise, Midday, Sunset (local time zones)
• Wind, Humidity & Pressure readings
• Global search (includes all supported countries)

DISCLAIMER

This application is not intended as a replacement for correct animal husbandry or to replace veterinary advice, it's role is simply to act as an additional early warning tool to advise when grasses at the location you have selected are likely to be 'under stress' and therefore to have accumulated excess non-structural carbohydrates (NSC, i.e. sugars, starch or fructan) which could significantly increase the risk of a laminitic episode should it be grazed.

This app can give you a warning when the risk of grazing induced laminitis is rising or high. However, individual horses vary widely in their ability to tolerate fluctuations in NSC levels so what is safe for one horse may not be safe for another. In addition, grazing is only one risk factor for laminitis and you need also to be aware of the risks posed by other causes, including toxins, metabolic problems and sugar and starch levels in hard feed, which cannot be measured by this app.

### 5/5 — Great tool we use daily

*2026-07-03*

We have the enhanced subscription and use this daily as a guide to allow safe grazing times for our horses , mini and donkey .

### 5/5 — A must have for metabolic horse owners

*2026-06-26*

I thought I understood in 
NSC in grass until I got this app and it’s an eye-opener when the values really are unsafe versus safe. I credit this with saving the lives of two of my worst cases and making them rideable again.

### 5/5 — Keeps my ponies safe.

*2026-04-27*

I’ve been using this app for years and haven’t had any more instances of laminitis. It tells me when the risk is higher and I adjust turnout accordingly. 10/10.

### 5/5 — Simple and useful

*2026-04-18, version 3.2.0*

Love the app. Daily notification for risk. Alerts for increased risk. Very useful app indeed.

### 5/5 — Love it

*2026-03-13*

Helps me figure out when and how long I let my horses out in pasture a huge help

### 5/5 — 12 years of helping manage EMS

*2026-03-09*

This APP has been a game changer for me, helping me every day decide if it safe to turn out my exceptionally sensitive EMS pony (with her muzzle on) The developments over the years have continued to improve the accuracy.  Obviously it is very important to continue to monitor condition and count calories as well as managing starch & sugar .. but the APP helps in a very real way… AMAZING!!

### 5/5 — Great help

*2025-11-30*

The app is a huge help. I went on vacation last year (didn’t know about app then) came back to laminitic ponies. It was awful. Now I use judgement along with the app-I would never rely solely on an app to determine what to do with my ponies….but it helps peace of mind when I see it in the high range they go out with muzzles on for just a couple hours.  When in the lower ranges I let them stay out longer. And vacation was much less worrisome! Thank you!

### 5/5 — Awesome!

*2025-10-23*

Really appreciate how this app helps me know when to turnout the horses on their grass or when to restrict grazing. Strongly recommend. It works in Canada.

**Developer response:** Thank you so much for your kind words! We're delighted to hear the app is helping you manage grazing and turnout decisions — and it’s great to know it’s working well for you in Canada. We truly appreciate your support and recommendation!

### 5/5 — Good tool

*2025-10-18, version 3.1.9*

I've been using this when needed for @12 years. Always found it to be reliable, enables me to see when it's safe to put them out on extra grass in autumn, keep and eye on sugar levels over winter when we have sunny days and frosty nights and when to start restricted grazing in spring.

### 1/5 — Dishonest  application

*2025-10-17, version 3.1.9*

I paid £5 for the app, then i'm told to use the app i have to spend another £20 to make it useful... refund requested
