Great for beginner runners to those experienced runners who want to refine their training program. The app gives you live and real time feedback on your pace - which is great for me as I am always running off my target pace. It provides feedback while running. Best suited if you have an Apple Watch with cellular connectivity but I used this app both using an Apple Watch and running with my phone. Definitely worth a try . ### 5/5 — Best Running App on the Market! *2025-10-20* I have been running for more than 20 years, and this is the best app I have ever seen. It gives you a large menu of workouts to choose from for every type of running workout a runner would do, and coaches you in your ear while you’re doing the workout. My coach also loves it! He’s in another state and we meet for workouts. It feels like he’s watching me! ### 5/5 — You need this app! *2025-10-05* If you wanting to up your run game and have an expert coach in your ear at all times, and this is the app for you! I highly recommend this app! ### 5/5 — Amazing!! 🏃‍♀️ *2025-10-04* I’m a brand-new runner and just tried KASI for the first time—absolutely LOVE it!! Honestly, I was a little nervous about starting my running journey, but with this app, it feels like I’ve got a super-smart coach who actually believes in me (even when I don’t) lol! The AI makes it fun, motivating, and weirdly personal—I swear it knew when I was about to slow down! The coach told me to keep going, when all I wanted to do was stop! lol I never thought I’d be the type to say this, but I’m actually excited to run again tomorrow. Watch out world, this new runner is officially hooked!! Can’t wait for my first 5 k run!! 🏃‍♀️🔥 ### 5/5 — Amazing! *2025-10-03* This is the most clever running-related thing I have come across in a long time. Every runner wants to feel like he or she has someone coaching them during their hard workouts instead of having to get through it on their own. The app knows what pace your supposed to run for all the different workouts in the app and tells you through your earphones what to do and when. But the even more clever feature is that my coach can watch my workouts from a distance live while I’m doing them and coach me like he is with me in person. That is so helpful! Every runner should run with KASI! ### 5/5 — Next Level Training *2025-10-03* KASI redefines run training with its real-time coaching feature. Whether guided by AI or a live coach, athletes receive instant feedback during workouts, making training more precise and effective. Instead of just tracking performance, the app actively supports runners in the moment—providing pace cues, reminders to control effort, and encouragement to push at the right times. This level of interactive guidance creates a true coaching experience on every run. For anyone seeking structure, accountability, and smarter training, KASI delivers far beyond the standard running app. ### 5/5 — Next level running app for all running levels *2025-09-26* Whether you're training for your first 5K or chasing a marathon PR, this run coach app is a total game-changer. From the moment I signed up, I felt like I had a personal coach in my pocket — guiding every step with expert advice, structured training plans, and real-time motivation. What I love most is how personalized everything is. The app adapts to my pace, fitness level, and goals, making it feel like the program was built just for me. The audio coaching keeps me focused and encouraged, especially on tough runs. And the progress tracking? Super satisfying and easy to follow. It’s more than just an app — it’s a partner that keeps me accountable, pushes me when I need it, and celebrates every win along the way. If you’re serious about running (or just getting started), this is the app you want by your side. 🏃‍♂️ Highly recommend. You won’t want to run without it. ## Frequently asked questions about RunKASI ### What is RunKASI?
