HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (2.7 new ratings a month on average since launch): revenue grows with new ratings, more slowly for apps that collect ratings fast. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

★★★★★ 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.
★★★★★ Would not recommend spending money on it.

★★★★★ 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.

★★★★★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.

★★★★★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.

★★★★★Sep 17, 2025
Such a great app

I started using this with skepticism, it took a sec but I am seeing real progress with a rigorous step by step improvement plan/ training companion. Give it a shot, it may surprise you. It definitely surprised me!

★★★★★Sep 15, 2025
Best Running app Ever

Get fast. Get fit.

★★★★★Sep 1, 2025
Hard Pass 👎

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. People are sick of subscriptions.

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.
