★★★★★ I wont recommend it at this price.
★★★★★ Wildly inaccurate predictions (I just ran a 5K PR 3 mins faster than what the app predicted me to run), and then the classic “Subscribe for $89 to use this app!” No thanks.
★★★★★ I was hesitant to write a review 4 ish days into my free trial because I assumed the app was new and they were still working things out.

★★★★★ Wildly inaccurate predictions (I just ran a 5K PR 3 mins faster than what the app predicted me to run), and then the classic “Subscribe for $89 to use this app!” No thanks.
★★★★★ Essentially just tracks your miles and predicts finishing times (which I am curious about the accuracy.) Got it thinking it would recommend workouts but in reality it is basically just a tracking app.

Latest reviews, Germany App Store.

★★★★★Sep 29, 2026
Good for influencers not for beginners or anyone else

I tried the app and its just an AI based app. Its better to just focus on your garmin predictions or just give a csv of your activities to chatgpt. The app is confusing to use, and not intuitive. I wont recommend it at this price. Not every mid app needs to cost 89.99€ / year. Maybe focus on developing the app a bit more instead of paying influencers.

★★★★★Aug 16, 2026
Wow !!!!

Best running app i‘ve ever test

★★★★★Jan 6, 2026
Unfortunate bugs

Love the concept but it’s hard to trust the app when it is presenting different mileage recommendations every other day and it can’t seem to add up my planned mileage correctly. It went from recommending 55 miles this week to now saying I have 19 miles remaining after one 8 mile run. It also reads that I have 7.5 unplanned miles despite having 52 miles planned.

★★★★★Dec 15, 2025
Best Race Performance Predictor

This app has really given me the confidence in my training being on track and about what I could achieve come race day.

★★★★★Nov 5, 2025
Customer Support & Adjustable Training

I have had positive interactions when reaching out to the customer support team, and within the app itself I appreciate that the training plan adjusts based on volume and intensity, providing some flexibility unlike a typical rigid training program.

★★★★★Oct 20, 2025
Doesn’t work

It seems that app is so buggy that it doesn’t work at all. Tried multiple times and it doesn’t even get past the first step.

Store description

kaizen is load-based run training for committed runners, starting with the running you have already done. Connect Strava, Garmin or Apple Health so kaizen can analyse your training and race history. See how your fitness is developing, what shape you are in now and what your training suggests is possible. kaizen then connects that picture with your goal and timeline to map the weekly training load needed ahead. kaizen does not process or store location data. Train toward a 5K, 10K, half marathon or marathon—or set a rate of improvement without an upcoming race. CHOOSE HOW YOU TRAIN Use a suggested training structure or build the week yourself: • Even Spread for a calm, repeatable weekly rhythm • 1 Long, 1 Hard to anchor the week around one longer run and one harder effort • Build Your Own for complete control over the week Choose structured workouts, plan your runs and see how each session contributes to your weekly target. ADAPT AS YOU GO Move or edit sessions when the week changes. Every completed run recalculates both your current fitness and the training load needed ahead. HOW LOAD WORKS Equal distances do not always represent equal training. kaizen uses distance, pace and elevation—along with supported cross-training minutes—to understand the load created by different activities. This keeps the bigger picture consistent while giving you control over how the work gets done. Start with a seven-day free trial.
