Best running app

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.

Paid version freezes

Paid version freeze all the time. I give up using it. Really disappointed.

Calculates distance wrong

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.

Great for years but now…

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.

Buggy with updates

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.

crashes mid run

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

Agree with others. Used to be excellent

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.

Richtig gut! … aber

Die App ist richtig gut. Ich nutze sie seit einigen Jahren und bin super zufrieden! Mein damaliger Auswahlprozess war recht aufwändig, aber iSmoothRun hat mit Abstand alle Anforderungen benutzerfreundlich erfüllt.

Seit kurzem nutze ich nun die Apple Watch 11, deren Unterstützung jedoch dringend ein Update benötigt, denn scheinbar wird das größere Display nicht unterstützt. Mit meiner Apple Watch 8 hatte ich keine Probleme.

Hoffe auf eine schnelle Lösung 😊

Mise à jour grand écran ?

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 ?

Crashes and loses workout

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.

dissapointment

map my run authorization does not work. they do not answer feedback e-mails as well..

Used to be Great, doesn’t work now

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.

Love the App, but a little less each day

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.

The best app for athletes

As a blind runner, I wanted to write a review to express my strong love to the app. I had tried a couple of apps to measure my heart rate, distance or so on. Until finding this app, none of them were fully accessible with the screen readers. This one is incredible.! I can create my workouts and I am able to choose the time for audio cues. The app has so much more to explore and I can confirm that it is the most inclusive and professional app for Athletes. I cannot even tell how much I love The Features of iSmoothRun.

App freezes

Sept 2025 - On the Ultra 2 watch this app freezes on most of my runs. You lose all the data.

Seems like it used to be good.

WorkOutDoors is the app I’m using now. Works much better.

Used to be good, but not anymore

I write a favorable review of this app 6 years ago. At that time it was in my opinion the best app the market. About a year ago the app started freezing up and losing running data. So disappointing that the developers seemed to have fallen behind. After trying to make this app work and losing data multiple times, I finally gave up and switched to another app called WorkOutdoors which is similar to ISmoothRun, but for me is much more stable and also more customizable. So unfortunately I can no longer recommend ISmoothRun.

Sync Watch und iphone?

Ich bin mit der App beim Laufen komplett zufrieden!
Wenn ich sie beim Rennrad fahren nutze, würde ich mir wünschen, dass Daten der Watch (z.B. Heartrate) auf das iPhone gespiegelt werden.
Geht das? Ich hab's bislang nicht gefunden...
Wenn das geht, geh ich auch an die Sterne nochmal dran 🤘

La migliore APP sul mercato !!!

É un app che fa tutto quello che serve per il running e molti altri sport. Oltre le più ottimistiche previsioni e aspettative. Il supporto è anche sempre presente e dettagliato e sempre in attività e disponibile per migliorare la app. La consiglio a tutti.

Nul remboursez !

Bugge en plein milieu de course sur l’Apple Watch, il faut payer un abonnement en plus de l’achat initial pour avoir accès aux fonctions avancées. Interface limitée à 3 champs par écran. Bref une grosse arnaque! Je souhaite être remboursé !
