It has kept me running steady. Some days I run and later on I get a push notification asking me to lace up my shoes- no! I ran already. As for cross training- I would like to be able to click as complete as it sounds pretty funny in a cross training class to have get ready to run said out loud from the online trainer. There are some bugs to work out. ### 4/5 — Great! *2026-03-22, version 6.5.27* I love the timer however my runs are not syncing and I am unable to connect to my watch ### 2/5 — I have purchased this app, now have to subscribe *2025-11-28, version 6.5.24* This app used to be a purchase, not subscription. I already paid for the app and should not have to pay a subscription fee just because i have not used it in a long time. ### 5/5 — Great app *2025-11-12, version 6.5.23* Love how easy and smooth is the training for my half marathon race and also the mix music albums ### 5/5 — I love it *2025-09-14, version 6.5.21* Honestly, I am a newer runner. I have done 5ks, a 10K, and now my first half. The app works, gives you a plan, it is very reinforcing in its set up, and honestly gets you to your goal. Give it a try! ### 5/5 — Works if you work *2025-09-03, version 6.5.21* I definitely recommend doing the 5k and 10K apps first. But as long as you do it to the best of your ability this will work. ### 5/5 — My favorite running app. *2025-07-23, version 6.5.21* I started with the Zen Labs C25K (which I’ve done for 10+ years every racing season) then decided to give this one a try. I love that I can play music on any app in the background and it talks over it to tell me when to start/stop running/walking. I love the warm up and cool down. I also love that it automatically links with my Apple Watch and Apple Fitness without me having to do anything. ### 5/5 — Best app *2025-07-21, version 6.5.21* I started with the 5k and have been working my way up. It breaks it down in a way that makes the distances feel obtainable! A great app! ### 5/5 — Easy to use *2025-06-27, version 6.5.20* I love that this app makes it easy to achieve my goal. I hit start and follow instructions. I’ve used the c25k app and liked it just as much. ### 5/5 — Half marathon jeffing *2025-05-04, version 6.5.19* So glad I downloaded this app 👍 Didn’t realise jeffing would make my pace better that all out and it has helped manage my breathing 😮‍💨 Roll on my London park half marathon in October 🙃 ### 5/5 — Great workout *2025-05-03, version 6.5.19* Appreciated the prompts and tracking ### 5/5 — Best trainer *2025-04-05, version 6.5.19* Love this, have worked up from c25k, great app ### 5/5 — Love it! *2025-03-10, version 6.5.18* Love this app. I’m in my late fifties, so no spring chicken. And as a beginner runner, it’s been a huge help in giving me structure and motivation in my training. It has made what at one time seemed overwhelming - running a half marathon - into a manageable and doable challenge. Def recommended. ### 5/5 — Great partner! *2025-03-10, version 6.5.18* This app makes a great run partner as I have restarted my own running journey after a few years of being out of it! ### 5/5 — Trying out *2025-03-01, version 6.5.18* Thanks for letting me try the app before purchase ### 5/5 — Great for older runners *2025-01-22, version 6.5.18* Took a break from running due to cancer for a few years. Gained some weight, lost some fitness, but this made it easy to get back into the swing of things. ### 5/5 — Love it *2025-01-20, version 6.5.18* Great way to start your cardio ### 5/5 — The best! *2025-01-18, version 6.5.18* The best running app out there! Hands down! You will be glad you invest it in your wellbeing. 😊❤️ ## Most critical reviews (10 lowest-rated) ### 1/5 — Why is this a subscription? *2025-11-29, version 6.5.24* I remember paying for the running app library a few years ago. I could probably restore my purchase and get some lesser version of the paid subscription mess they’re pushing now, but I don’t want to support an app that refuses to let its backers own the software they think they’re paying for. The inability to permanently disable the flock of obnoxious tracking requests every time I start a workout is pushing me out of using this company’s apps entirely. I never thought Nike would have a better running app than Zen. I’m sad the company went this way. ### 1/5 — RIP off *2025-07-01, version 6.5.20* I bought and paid for a full product a few years ago and “due to the current climate” they have changed to a subscription, this means the full product I bought is no longer valid. I have the 10K, 13.1 & 26.2 app and the 10K is the only app that works and hasn’t moved to subscription. I won’t hold my breath on how long I’ll still have access to that one. ### 1/5 — Poor Service *2024-08-22, version 6.5.15* This app is just a timer really, but it’s simplistic no frills design so a feature not a bug. if you want the most basic timer for jogging ever this is it. Bought this app and another from them. Sometime later my app stopped working and they trying to charge a monthly fee for something I already bought outright. Made a number of attempts to solve this with support but was brushed off after providing proof of purchase. They kept offering me free trials instead a refund of even better .. restoring what I paid for already. ### 1/5 — Never actually get to run! *2024-08-08, version 6.5.15* I used the C25k and 10K apps and had great success. Each starts slow but eventually you are running for the full time (other than warm up/ cool down). I expected the half marathon app to be similar, but it has you do a run-walk repeat all the way up until the race. This is useless to me as someone who can already run a 10K. Instantly deleting and unsubscribing! ### 1/5 — Where did my app go?! *2024-03-22, version 6.5.10* So I have used this app along with the marathon, c25k and 10K apps for years. Now when I try to open any of these apps on my iPhone 12 Pro (which I had no issues with doing before) I get a white screen and nothing comes up. I have a strong WiFi connection and stable internet when I’m trying to use this app and nothing! Very frustrating when trying to plan out a workout schedule for a new 1/2 marathon. I am paying for the subscription for the use of all 4 of these zen lab apps. Why can I not access them now? Starting to feel like I am being scammed by the company. Pay for a subscription but we won’t give you the services you paid for…. ### 1/5 — Dishonest company! *2024-01-26, version 6.5.10* I paid for this a long time ago and now I have to pay for a subscription not very trustworthy company. ### 1/5 — New subscription model *2023-11-13, version 6.5.9* I purchased this years ago and now I have to buy a subscription to use the app that I already purchased?? Weird. ### 1/5 — Money grab *2023-08-12, version 6.5.5* Awful subscription-based service. ### 1/5 — Purchased the app, then they switched to a monthly subscription *2023-07-03, version 6.5.5* I purchased the app years ago, now all the sudden they want to charge a monthly subscription. So after buying the app I now need to also pay a monthly subscription. Bad way of doing business Zenn Labs ### 1/5 — Abandoned their customers *2023-06-17* I purchased the bundle with all of the running apps 6 years ago, but now due to their subscription model they have taken away the program from those who already paid for it. I feel taken advantage of, charging nearly $30 for a software bundle only to make it unusable due to a business model change. It’s unfortunate that everything has gone to a “subscription model.” Especially when the model doesn’t really give anything new from what was previously available. Stay clear, there’s better options out there. **Developer response:** We apologize for any frustration you may have experienced with the change to a subscription model. We understand that this can be difficult, and we want to assure you that we made this decision with the best interests of our users in mind. We've added many new features, including music streaming, which we believe enhances the overall user experience. Please email us at contactus@zenlabsfitness.com with your original download date receipt, and we’ll certainly do our best to work with you. Thank you for your understanding. ## Most praised reviews (10 highest-rated) ### 5/5 — Great help and motivation *2026-08-25, version 6.5.31* It was great having the voice telling me when to start and stop. ### 5/5 — Great start *2026-08-25, version 6.5.31* I liked how user friendly it was while running. I appreciate the features that are available for free. ### 5/5 — BEST. RUNNING. APP. EVERRR!! *2026-08-25, version 6.5.31* I first used the 5k version and it got me into running 5k without stopping and went from a 1hr PR to a 34min PR! Now I’m training for my first half marathon and I know I’m going to kill it thanks to this training plan. The 5k is free and it got me here, the subscription is completely worth it for this one! You can play your own music no interruptions, it doesn’t have annoying ads, connects directly with your Apple Watch and strava! I can’t recommend this app enough! I got all my cousins running now with the 5k plan 😂🩷 ### 5/5 — Love it *2026-08-08, version 6.5.30* So easy to use ### 5/5 — This app made me believe I can run! *2026-07-16, version 6.5.30* I had never believed I could run, now I walk and run confidently. Thank you - the music helps too! ### 5/5 — Such a great training app *2026-04-05, version 6.5.28* Love the simple commentary and the clear plan. ### 5/5 — Great app *2026-04-01, version 6.5.27* Downloaded this years ago and I come back to it every time I fall out of shape. Easy to follow and good motivation. ### 5/5 — Greatest training plan *2026-03-03, version 6.5.27* I started with the 5K trainer and have worked my way up to the 13.1. Ran my first half this past December and did it in 2:13. I recommend this for anyone wanting to get started ### 5/5 — Greatest training plan *2026-02-20, version 6.5.27* I started with the 5K trainer and have worked my way up to the 13.1. Ran my first half this past December and did it in 2:13. I recommend this for anyone wanting to get started ### 5/5 — Good motivation *2026-01-08, version 6.5.26* Sometimes you need a little motivation and this app does that. Alerts to workout. Pep while working out. And you can take pics when you finish. At the end you have a large collection to show you the hard work you’ve accomplished. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
