### 4/5 — I love this running app!

*2021-02-24*

I use this app while training, establishing running goals and when I use race comparisons during my training cycle.
This app is spot on, I’ve used it for 6 different PR’s and 5 BQ’s, it’s great!

### 2/5 — Glitching

*2021-02-21*

Just bought and downloaded this and the app keeps glitching immediately after opening, then shutting self down, which means I can’t even start calculating paces... maybe an upgrade is needed?

### 3/5 — Good App but missing some key info

*2019-12-12*

This is a very handy app but I wished it showed the vLT and vVO2 data like the McMillan website does.

### 1/5 — DO NOT BUY - not being maintained!!!

*2019-11-02*

Should have checked to see when the last update was but assumed it was still being worked on since it’s still advertised on their site. 

Do not buy: not updated to work well in modern phones.

### 1/5 — Don’t buy this app.

*2019-10-20*

This app is not worth the money. It only calculates your run/race times based on recent race times. It does not allow you to specify GOAL times and give you training times based on GOALS. 

They are stealing money by still leaving this APP on the AppStore and haven’t updated it in 3 years. This is a rip off.

### 1/5 — McRun App constantly crashes

*2019-09-26*

I updated my iPhone to iOS 13 and now the iOS McRun constantly crashes. I have tried to delete and reinstall it several times to no avail. Any ideas to get it working again or get an update for iOS 13? And please add the “goal times” calculator!

### 1/5 — Unstable - don’t install

*2019-05-18*

I bought this app today - 18-05-2019 - for my iPhone X with up-to-date iOS and it launches, then shuts down spontaneously in 3-6 seconds, i.e. it is completely unusable. I have contacted the app developer.

### 1/5 — Always crashing

*2019-04-30, version 1.9*

This app is fantastic, when it isn’t crashing immediately after being opened...which is 90% of the time on my iPad Pro.

### 4/5 — Great app, useful information

*2019-04-08*

Easy to use, handy app

### 5/5 — Nice!

*2017-08-31*

Easy, good app!

### 1/5 — Terrible

*2021-06-07*

Paid for the app but it won’t even open!

### 1/5 — Doesn’t even open

*2021-05-17, version 1.9*

Bought it and it doesn’t even open! I want a refund!

### 1/5 — Doesn’t work on iOS 14.4

*2021-02-05*

It can’t open on iOS 14.4. 5y without updating the software. I paid 11€ for this .....

### 1/5 — App crash

*2020-10-01*

Just purchased the app and it crashes upon opening. Please provide a refund. A $9.99 app and it won’t even open. This makes me hesitant of purchasing a training plan from their website. This app should not be in iTunes if it is no longer being updated or monitored by the developers or the Macmillan Staff.

### 1/5 — Crashed Immediately after initial install

*2020-08-29*

I installed the app on my iPhone XS Max, opened it and the app immedialty crashed.  I deleted it and reinstalled but it still didn't work.  All other apps were shut down, still nothing. 

Waste of $9.99.

### 1/5 — Just crashes

*2020-07-16*

Crashes 5 seconds after opening.

### 1/5 — Not working in my iPhone 6s

*2020-02-09, version 1.9*

I downloaded and it opens and the close by itself immediately. It doesn’t allow me to do anything. I need help please!

### 1/5 — Does not work

*2020-01-19*

I am hoping that the devs are still reading please as I have just purchased the app and it does not run on my iPhone XS Max 523MB.
Can we get it working or provide a refund please?
Thank you.

### 1/5 — App crashes when I try to open it

*2019-11-29, version 1.9*

I just downloaded and it crashes every time I try to open it.

Can’t get app support because I can’t open the app.

### 1/5 — App not worth the price

*2019-11-06*

This app does not do everything that the online calculator does through the website.  It is very limited and for what you get, there are a lot of options online.

### 5/5 — McHelpful

*2025-09-24*

I like McRun because it’s very easy to use, you just throw in some times and it quickly gives you a variety of workout paces.

### 5/5 — The best!

*2025-07-11*

I’ve been using the calculator for years to help set my training paces to help achieve my running goals.  Easy to use and accurate!

### 5/5 — Great Training Aid

*2021-08-07*

Really helpful in providing focus for training.  Recommended paces are just right.  Training for a marathon and this app is awesome.  Helped me BQ!

### 5/5 — For runners

*2021-04-09*

Great wee app for runners who like to geek out over speed

### 5/5 — Awesome

*2020-03-27*

It’s accurate. Great app

### 5/5 — So helpful!

*2020-01-29*

So helpful for runners and coaches from novice to elite!  Quickly find out what your race goal time should be at a new distance or what pace you should for a new workout.

### 5/5 — Always Training.

*2019-07-17*

Very straightforward and always easy to refer back to. A highly useful and in some cases critical tool for effective training.

### 5/5 — Run faster

*2018-07-22*

I’ve been using this app for a few years. I was dubious at first having to pay for it. But it has paid for itself with countless pbs. 

This app has helped me to train smarter but learning about which pace to run for different distances. 
It’s also helped me to workout if dream times are achievable. 

This app has definitely helped me to train smarter and get faster.

### 5/5 — Love McRun!

*2018-04-25*

Such a great app for coaching and my own training: paces are spot on!

### 5/5 — Fait ce pour quoi il est prévu

*2017-10-14*

Utile pour les programmes d’entrainement de mac millan et l’ajustement de leur difficulté.
