What clients actually say about coaching apps
We read 414 public App Store reviews across ten coaching platforms and twenty-two countries, and pulled out the 164 critical ones. This is what keeps going wrong, with the test that would have caught each one during a free trial.

The short version
One theme dominates and it is not a missing feature. 35% of critical reviews describe the app crashing, freezing or losing logged work, and it appears in 7 of the 10 apps. Nothing else passes 12%. The most widespread complaint is a different one: cancellation friction, at only 10% by volume but present in 8 of the 10 apps.
The pattern underneath all of it is the one worth acting on: your client blames you for what the app does, because you are who they pay.
How we did this, and what it does not prove
We pulled public customer reviews from Apple's App Store feed for ten coaching-platform apps across twenty-two storefronts, including the US, UK, Canada, Australia, France, the Nordics, Germany and the Netherlands. That gave 414 unique reviews after deduplication, of which 164 were rated one to three stars. We grouped those 164 by the problem being described. A review can count in more than one theme.
Three things worth knowing before you use these numbers
It is not a scoreboard. The public feed returns recent reviews rather than a representative sample, and people write reviews when they are annoyed. Lifetime ratings for these products are high: Trainerize averages 4.9 across more than 66,000 ratings, TrueCoach 4.9 across more than 34,000. Nothing here means a given platform is badly rated, and we have deliberately published no per-platform league table, because this sample cannot support one.
Not every reviewer is a coach. Most of these are the client-facing app, so most reviewers are somebody's client. A few of the angriest reviews are really disputes about a coaching package bought from a coach, filed against the software instead. We kept those out of the billing theme. They are the clearest evidence for the finding below.
Read the spread column, not just the percentage. A theme at 11% across 6 apps is a category norm you should expect anywhere. A theme at 11% across 3 apps is a specific product problem. We publish both numbers for every theme, because the second one changes what you do about it.
Two themes were dropped after inspection rather than published: one turned out to be a keyword artifact, and one rested on five reviews. Two others, crashes and lost work, were merged once it was clear the reviews were describing a single failure from different angles.
The finding: your client cannot tell your coaching apart from your software
Read enough of these and the same structure keeps appearing. A client writes that the coaching was fine, or even good, and then lists the app as the reason it was not worth the money. Several reviews complaining about being charged, or about not being able to cancel, are describing an arrangement with a human coach and filing it against the platform, because the platform is the thing with a review box.
That asymmetry is worth sitting with. Clients touch the coaching once or twice a week. They touch the app every day: to see the session, to log it, to send a photo, to answer a check-in. The app therefore carries far more of the impression of your service than its share of the value, and it collects the blame for anything adjacent to it, including your billing.
The practical version: software reliability is not an IT concern you can hold separately from coaching quality. It is part of the service, and your client is already treating it that way.
The seven failure modes, ranked
Share is the percentage of the 164 critical reviews mentioning that theme. Spread is how many of the ten apps it appeared in.
The app crashes, freezes, or loses the work
35%appeared in 7 of 10 apps
One theme dominates this entire corpus, and it is not a missing feature. It is the app failing while somebody is using it. The most quoted version is a client most of the way through a session when the logged sets vanish. Around it sit freezes on exit, hangs while uploading a progress photo, sync that arrives days late, and history pages that take half a minute to load. Reviewers who had used a product happily for months often date the problem to an update.
Crashes at least 3 times during every workout.
Test it: Log a full session as a client. Force-close the app mid-workout, switch to another app, let the screen lock, then come back. The sets should still be there. Do it on a weak connection, not on office wifi, and do it the week after an app update if you can.
Messages and notifications do not arrive
12%appeared in 7 of 10 apps
Second by volume and joint-second by spread. A message the client never sees looks exactly like a coach who did not reply, so this one converts directly into a complaint about you. Reports cover missing push notifications, comments that never surface, notification settings that reset themselves, and in-app alerts that fire for the wrong thing.
Every time I log something in the app, or the timer finishes, or if i switch out of the app and then back to it, it pauses my music.
Test it: Send yourself a message as a client with the app closed and the phone locked. Confirm the push arrives, and that tapping it lands on the message rather than dumping you on the home screen.
Food logging is inaccurate or gives up
11%appeared in 3 of 10 apps
Concentrated rather than widespread, which is the point of the spread column: this is not a category norm, it is specific products doing it badly. The complaints are technical and precise. Wrong macros behind a scanned barcode, custom foods that cannot be found again after being saved, servings that do not multiply correctly, and databases that do not contain food sold outside the United States.
Also, when I scan in a barcode for a given food, the macros are sometimes off as well as the title.
Test it: Scan five things your clients actually eat, including one supermarket own-brand product from your country, and check the macros against the packet. Then create a custom food, save it, and try to find it again tomorrow.
The exercise and video library gets in the way
11%appeared in 6 of 10 apps
Same volume as food logging but spread across twice as many apps, so this one is closer to a category norm. Two problems sit under it. Coverage: the demonstration a client needed was not there and they went to YouTube. And timing: videos that only appear once the set has started, no view of what is coming, and no record of last week weights while you are standing at the rack.
It should allow you to see the videos and tutorials in advance and not on the moment you start your workout.
Test it: Search the ten exercises you program most. Then run a session as a client and check whether last week weights are visible at the moment you need them, without leaving the screen.
Cancellation is harder than signing up
10%appeared in 8 of 10 apps
The most WIDESPREAD complaint in the corpus. Lower by volume than reliability, but it appeared in 8 of the 10 apps, which makes it the closest thing here to a category-wide norm. Reviewers describe subscriptions that kept charging after cancellation, twelve-month commitments they did not know they had agreed to, and being bounced between the vendor and the app store over who owns the billing relationship.
The functionality is basic and not on parr with much cheaper alternatives that are readily available and also do not sign you into a 12 month contract!!
Test it: Before you enter a card, find out whether the plan is monthly or an annual commitment billed monthly, and find the cancellation route in writing. If the pricing page does not answer it, ask support and keep the reply.
Support answers slowly, or answers the wrong question
9%appeared in 4 of 10 apps
Not simply slow replies. The pattern is support that asks clarifying questions without investigating, and reviewers who describe quality declining over time on a product they used to recommend. It clusters with billing disputes far more often than with bugs, which suggests the hard cases are the ones handled worst.
If you really have a complaint you cannot get past customer service/sales team to anyone that will actually help.
Test it: Send a genuinely awkward question during the trial, about billing or data export rather than about a button, and time the reply. You are buying the support as much as the software.
Wearables and health apps connect only halfway
6%appeared in 3 of 10 apps
The smallest theme kept, and the one most likely to matter to a specific kind of client. Integrations that read part of the data and silently drop the rest, workouts that do not stop on the watch when they stop on the phone, and activity that has to be entered by hand despite a connected account.
When I stop my work out, the app does not stop on my watch so I end up with my fitness app thrown off because my watch has been tracking the last 8 hours of my life.
Test it: Connect whatever your clients actually wear, then check field by field what arrives and what is missing. Partial integrations are the norm, not the exception.
The trial checklist, in the order that matters
Every platform demo shows you the coach view, because that is the view built to impress a buyer. Almost every complaint in this corpus comes from the other side of the product. So run the trial as your own client, on your own phone, for a week.
- 1.Log a full workout, force-close the app half way through, and confirm nothing was lost.
- 2.Read the cancellation terms and find out whether the plan is an annual commitment.
- 3.Send a message with the phone locked and confirm the notification arrives.
- 4.Scan five foods your clients actually eat and check the macros against the packet.
- 5.Run a session and check that last week numbers are visible when you need them.
- 6.Upload a progress photo over mobile data, not wifi.
- 7.Ask support an awkward billing question and time the reply.
- 8.Connect a wearable and check field by field what actually arrives.
Where Coachway stands on this list
It would be convenient to claim none of the seven applies to us. Every coaching platform ships bugs, and any vendor telling you otherwise is selling. What we can be specific about is where we have deliberately spent effort, because these were the same complaints we heard from coaches before we built anything.
On food logging, clients log against a database of 3.7 million foods, and when a scanned barcode is not already in it we run an additional lookup and save the result, so coverage of local and own-brand products grows with use rather than being fixed at launch. On cancellation, billing runs through the coach's own Stripe account, so the client's payment relationship is with their coach rather than with us, and coach data exports to CSV or PDF at any time. The client app is localised in six languages and reviewed by native-speaking coaches, which removes a class of confusion that does not show up in an English-language review corpus at all.
The honest framing is that this list is a checklist to hold us to, not a scorecard we have already won. Run the eight tests above on Coachway during the trial, and run them on whatever else you are considering.
Questions
What do clients complain about most in coaching app reviews?
Reliability, and it is not close. Across 164 critical reviews of ten coaching platforms, 35% described the app crashing, freezing or losing logged work, and that theme appeared in 7 of the 10 apps. Nothing else passed 12%. The most quoted version is a workout that vanishes part-way through a session. That matters more than it sounds, because the client blames the coach for it, not the software.
Are these reviews a fair measure of how good each platform is?
No, and this page does not use them that way. The public review feed returns recent reviews rather than a representative sample, and unhappy users write sooner and more often. Lifetime ratings for the major platforms are high: Trainerize averages 4.9 across more than 66,000 ratings and TrueCoach 4.9 across more than 34,000. We have deliberately published no per-platform league table, because this sample cannot support one. What it legitimately shows is which failure modes keep recurring across different products, which is the useful thing when deciding what to test during a trial.
Do clients blame the coach or the app when something goes wrong?
They blame whoever they pay, which is the coach. Reviews regularly describe a lost workout, a failed sync or a wrong calorie count as a reason the coaching itself was not worth the money. Several one-star reviews filed against a platform are really disputes about a coaching package the client bought from a coach. The practical consequence is that your software reliability is part of your service quality whether you like it or not.
What should I test during a free trial before committing to a coaching platform?
Test the things that recur, and test them as a client rather than as a coach. Log a full workout and force-close the app part-way through to see whether the sets survive, because that is by far the most common failure. Scan barcodes on five foods your clients actually eat and check the numbers. Send a message with the phone locked and confirm the push arrives. Then read the cancellation terms before you enter a card, because billing and cancellation complaints appeared in 8 of the 10 apps, the widest spread of any theme.
Which complaint is the most widespread across different platforms?
Billing and cancellation, which showed up in 8 of the 10 apps despite being only 10% of critical reviews by volume. Reliability is bigger by count at 35% but appeared in 7 apps. Spread and volume are different signals: a theme with a high percentage concentrated in one product is that product problem, while a theme appearing in almost every app is a category norm you should expect wherever you go.
Does a bad client app really lose coaching clients?
The reviews suggest it contributes. A recurring pattern is a client who describes the coaching as good and the app as the reason they stopped, or who cannot separate the two. Since the app is the part of your service clients touch every day and the coaching is the part they touch weekly, the app carries more of the impression than its share of the value.
