### 5/5 — Best running app

*2026-08-05, version 7.0.10*

I have been using iSmoothRun for years, now. I found it when researching the best running apps available. I'd been looking for something that would allow me to do customized interval training.

ISmoothRun did not disappoint. It has consistently been the best running app for years.

I used it to learn to run 5k, to improve my 5k, and to train for 10k runs.

### 1/5 — Calculates distance wrong

*2026-07-01, version 7.0.10*

Used to love this app.  Lately it’s been calculating distance incorrectly, which means it’s also giving an incorrect pace.  I’ve tried adjusting settings for this, and reached out multiple times to the developer without getting any repsonse back.

### 3/5 — Great for years but now…

*2026-06-24, version 7.0.10*

I’ve been using this app for 12 years and it’s been brilliant but suddenly, and not as a result of any update, ALL of my past activities have disappeared! 12 years worth of records gone and no response to my messages requesting assistance.

### 4/5 — Buggy with updates

*2026-03-20, version 7.0.10*

I really like the app and flexibility. However, it is often buggy. For instance, I just upgraded to an ultra and now I cannot end workouts. The app gets stuck on a screen but you cannot swipe to end the workout.

### 3/5 — crashes mid run

*2026-03-14, version 7.0.10*

I like the app, use it for cycling and running but recently it has been crashing on my apple  watch mid run , no workout gets recorded. v disappointing. may need to use phone again, but that defeats the point of having a watch only option

### 1/5 — Agree with others. Used to be excellent

*2026-01-14, version 7.0.10*

Used to be my go-to app for most activities and loved so much about it, but I finally cancelled my subscription because the app isn’t keeping up with iOS updates. Constantly need to restart watch or phone to get a proper and inconsistently reliable connection. HR capture variable. Just a struggle. Would love to return to the app but can’t trust it anymore.

### 3/5 — Mise à jour grand écran ?

*2025-12-31*

ISmoothRun est toujours bien pour gérer les capteurs de course, mais j’aurais aimé un écran d’affichage plus modulable et compatible avec les écrans actuels. Il a beaucoup de place vide en haut de l’écran . L’application est elle abandonnée ?

### 2/5 — Crashes and loses workout

*2025-12-26, version 7.0.10*

Shows promise but it’s not the best app, and additionally they have crashes on the latest watchOS which means you can’t end your workout and you’ll lose the whole run.

### 1/5 — Used to be Great, doesn’t work now

*2025-11-15, version 7.0.10*

Was a great app and when it works it still is but I run with an Apple Watch and now every run the app freezes and workouts aren’t recorded. It’s incredibly unfortunate since it was such a good app and now I can’t even use it. On the odd occasion it does work it still records everything and is excellent but it’s is always a risk so I barely use it anymore.

### 2/5 — Love the App, but a little less each day

*2025-10-16, version 7.0.10*

This was a fantastic app and I used it for years and achieved great weight loss and fitness goals. Unfortunately I broke my neck and I was out of it all for a few years. 
Now I’m back and I’m finding this app hasn’t been kept up to date. It’s been a year since the last update. I’m n that time iOS upgraded, most people’s phone upgraded and most people upgraded their smart watches. 
This app hasn’t kept up. 
Still a good product but diminishing quickly.
