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 ### 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. ### 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. ### 2/5 — Used to be good, but not anymore *2025-08-17, version 7.0.10* 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. ### 2/5 — BRAZILIAN PORTUGUESE *2025-06-20* Não tem versão em português! ### 2/5 — Great idea but HR inconsistent with strap *2025-05-19, version 7.0.10* So when are the bugs going to be fixed. Over a year now ### 3/5 — La meilleure application running *2025-02-19* Mais dommage que l’on ne puisse pas voir le parcours faits en fin de course, ne transmet pas les données gps à l’application santé. ### 3/5 — Так себе приложение *2024-11-06* Так себе приложение. Все на английском языке, интерфейс очень ограниченный, показателей мало. Вообще какое то примитивное для своей стоимости. ### 3/5 — Great but only 50% of the time *2024-11-01, version 7.0.10* This app works so well when it works, but 50% of the time it does not do what it is supposed to to and I cannot predict on which day it will fail. I load my running program into training peaks and can view the workout on the app. I will select the app, make sure audio cues are turned on and then cross my fingers. It is so helpful doing sprints and progression runs when it works but horribly frustrating when for no reason it just ticks off the miles and does not reference the selected workout. I have tried everything from rebooting my phone before every run, making sure all of my apps are up to date, and even create small fake workouts to test it. Also, the design of the main screen is awkward. Seems with all of the capabilities of an iPhone a much clearer rendering of workout statistics is possible. ### 1/5 — App on Ultra no longer working *2024-10-24, version 7.0.10* Since the latest iOS update app on Watch is useless. I have rebooted, removed and reinstalled. Not recording mileage and freezes up. ### 4/5 — It’s great apps but there was a problem *2024-10-15* I’ve used the apps 2019. Everything is great especially for interval workouts! But last week there were two times when the apps frizzed in my Ultra Apple Watch during in the middle of my workout . I’ve heard by my EarPods it’s works but it was impossible to finish it. Unfortunately the statistics was lost ¯\_(ツ)_/¯ ### 1/5 — Does not work with Apple latest updates - WatchOS 11 *2024-10-09, version 7.0.10* I have contacted owners 3 times without response - tue latest Apple updates in Sept 2024 means iSmoothRun no longer works. The watch app either doesn’t record anything but time or it freezes on the first split. Help! ### 4/5 — A sad goodbye *2024-10-08, version 7.0.10* This was my major running/walking workout app for many years, chiefly because it included audio cues for heart rate zones, which are not easy to find in app of this type. Recently, however, I find that the app has become buggy and unreliable and the interface outdated. Since I came across another app at this type that has the audio cues. Since there hasn't been a major update in a very long time I'm afraid I'm just going to go ahead and delete it. Oh well. ### 1/5 — Uses to be the best app *2024-09-22* Now, impossible to use with WatchOS 11.0. The app crashes and all the run is lost. I tried twice, lost both of my runs. 7 months without an update! What is happening?? ## Most critical reviews (10 lowest-rated) ### 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. ### 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. ### 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. ### 1/5 — App freezes *2025-09-03, version 7.0.10* 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. ### 1/5 — Nul remboursez ! *2025-06-11* 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 ! ### 1/5 — Used to love it, but it is no longer supported *2025-03-11, version 7.0.10* I used this app religiously for many years but recently it started having several issues and all attempts to reach out to support were ignored. ### 1/5 — Freezes and no dev reply *2025-02-14, version 7.0.10* Splits notification have caused the iSmoothRun display on my Apple Watch to freeze since November, intermittently and usually on mile 1 or 2 of a walk or run. Disabling splits notification stopped the freezing, then as soon as I re-enabled splits notification the freeze happened again. I’ve sent 4 emails to the developer but gotten no reply. I paid $24.99/year for at least 4 years. Now I must try to find another running app. ### 1/5 — Used to be great *2025-01-05, version 7.0.10* It doesn’t sync with Garmin app anymore and it constantly freezes and crashes even after re installing ### 1/5 — The developer no longer supports the mobile app *2024-12-16* The developer no longer supports the mobile app ### 1/5 — New Apple software, app isn’t working *2024-12-11, version 7.0.10* Since last week when Apple updated my watch and phone, this app has stopped working properly. The update was to OS 11.1, and since this update the watch app will start okay, but after it gives me stats it will freeze on the stat screen, not let me close the stat screen, keeping it frozen and I can’t stop the app from running until I turn my watch off. I’ve contacted the company twice, but have gotten no response that they have the issue or plan to fix it. Will be looking for another app. I really liked this one before this issue. ## Most praised reviews (10 highest-rated) ### 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. ### 5/5 — Super!!!!! *2024-11-16* За приложение не платил, бесплатная версия устраивает полностью, пользуюсь очень давно. Да только English и что? Всё понятно. Потрудитесь переведите. Это же интересно. Для меня отличное приложение, спасибо разработчикам. ### 5/5 — My fave for years *2024-10-05, version 7.0.10* Have used this app for years and love it. Functionality is great and reliability rock solid, incl. watch integration, which is excellent. Clearly made by people passionate about running. It’s not a social media app like, say, Strava though; for me this is a plus too. ### 5/5 — My trusty running app for over 10 years *2024-09-04, version 7.0.10* This is the best free running app! I’m able to scroll back 10 years to see how many miles I ran, how long took, etc I love that I can program various workouts from marathon training, regimens to sprint intervals. This app never has any issues and I love that it is free! ### 5/5 — Best app for running, biking on iOS *2024-08-31, version 7.0.10* Love it. I’ve been using it with Apple Watch for several years. Had to switch to using it just on iPhone when my watch crashed, and love that workouts can be recorded directly by its iPhone app. Have new watch now and the app seamlessly installed on it. ### 5/5 — Amazing - has every feature you could want *2024-05-21, version 7.0.10* Has every feature you could want ### 5/5 — Have used app for years and still love it. *2024-05-08, version 7.0.10* It allows me to set my intervals and I love it. I like to run using my heart rate as my guide and this app gives me so many options. ### 5/5 — Great app. For running *2024-03-03, version 7.0.10* I use this app with Polar heart rate and Stryd foot pod. I can’t remember when I first started using the app it has been such a long time. It works great and records all the stuff I want. It always works for me. I’ve used it in places with no cell service with no problems. I’ve used the watch app only and together with the phone. It loads data to Apple fitness. This is one of those apps I love because it always works for me. Polar can be a bit dodgy so I occasionally need to re- pair it. But that is a polar thing not this app. My only wish is bigger numbers as there seems to be some extra screen real estate since I can’t see the small stuff without reading glasses. ### 5/5 — Interval training *2023-06-18, version 7.0.6* Best app I’ve found for setting up custom intervals ### 5/5 — Best running app available! *2023-05-24, version 7.0.6* No need for Garmin-now I can stream my music too and leave my phone behind, with my Apple Watch Ultra. Highly configurable app. You can set up virtually any interval run you like with various paces, etc. I love the audio cues and their customizability, especially love the pacing cues that tell me if I’m ahead or behind. Top notch app. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
