Planet Fitness App Won't Log In? 169 Reviews (2026)

If the Planet Fitness app emails you a sign-in code and then does nothing when you tap Continue, stop trying. Walk in and ask the front desk to check you in with your phone number, which is what most of the people writing these reviews ended up doing anyway.

That is the practical answer. What follows is why it happens, what it quietly costs you if you leave it unresolved, and which of the reader workarounds actually appear to work.

How We Counted

On 8 August 2026 we pulled the 500 newest US Google Play reviews for the Planet Fitness app and the most recent App Store complaints, then swept six non-English storefronts for reports that never surface in English.

On Google Play, 243 of the 500 were rated 1-3 stars. After dropping reviews too short to categorise, 148 remained, spanning 27 April to 6 August 2026: 124 one star, 13 two star, 11 three star. The App Store side returned 21 categorised 1-3 star complaints from 2026. That is 169 categorised complaints, plus 34 more from the Spanish, French and Portuguese language storefronts.

Both stores are on the same build, which matters later: this is not a platform problem.

Signing In Is the Largest Cluster by a Wide Margin

47 of the 169, 27.8%, cannot sign in, which makes it larger than every other theme in the set. On Android alone it is 43 of 148, 29.1%.

What makes this cluster useful is that the reports are not vague. They describe the same three-step sequence, and they stop at the same step:

It sends the code to my email to sign in, then when I enter it on the app the continue button is dead in the water.

I put in my email address. it sends me a code. I get the code, enter the code as asked. hit continue and it freezes up. I've done this 9 times in 2 days.

Nine attempts across two days is the kind of detail that rules out a bad moment on a bad network. A third reviewer reports the failure one step earlier, at the point the code is supposed to arrive:

ive requested to receive a one time code via email and you never send it! I receive other emails from it but the verification code!

And a fourth describes what happens if you try to solve it the obvious way, by resetting the password:

Login requires emailed one time code, takes forever to show up in box. Wanna recover your password, literally same process, except this time your email address will get locked out for to many requests.

That last one is the most expensive detail in this article. The recovery path and the login path use the same email delivery, so hammering the reset button does not give you a second route in. It takes away the first one.

The App Hands You Off to a Web Page and Loses Track

Several reviewers describe a specific version of the loop where the sign-in happens somewhere other than the app:

won't let me login. it take me to the website I login and stay on the website when I go back to the app its still not logged in.

I've gone to my local Planet Fitness 3 times for help with the app because it keeps redirecting me to the website instead of working.

That is a session that is created in a browser and never makes it back into the app. It also explains why reinstalling does so little for the people who try it: the credentials were never the problem.

One more constraint shows up in the set and is worth knowing before you try to sign in on a second handset:

If you log in on 2 devices (yes TWO) you get kicked off for being “logged onto too many devices”.

What the App Is Actually For

Almost all of this matters because of one screen. One reviewer put the app's job in a single sentence:

95% of this app's purpose boils down to "generate a QR code to check me into the gym". I find that it consistently takes about 20-30 seconds to do this

24 of the 169, 14.2%, are about check-in specifically: the QR code, the barcode, or the scan at the door. When the sign-in fails, that is the thing you lose, and the reviews show exactly where the cost lands:

Now the employees have to manually enter my phone number everytime I go and I can’t access the app.

Another told me to wait a week and gave me a temporary barcode while also saying the app was required. The staff were kind, but after 3 visits my issue still isn't resolved.

Support, according to one reviewer, has settled on the same workaround:

finally emailed customer support and "support for login help isn't available but your local club can check you in" that's not the problem.

There is also a smaller and stranger failure worth flagging, because the person it happens to will assume they have been cancelled:

this app randomly deleted my linked membership, removed my QR code, and now treats me like a nonmember. Instead of letting me check in, it tells me to “Join Now” and tries to sell me an entirely new membership I already pay for.

Step 1: Ask the desk to check you in by phone number

This works today and it works while everything else is broken. It also means a login problem never has to cost you a workout. Several reviewers describe staff doing this routinely, so you are not asking for anything unusual.

Step 2: Request the code once, then wait

The most common self-inflicted wound in this set is requesting a new code every thirty seconds. Reviewers report codes arriving slowly, arriving out of order, and eventually not arriving at all once the address has been hit too many times. Ask once, give it a few minutes, and check the spam folder before asking again.

Step 3: Do not use password reset as a retry button

If the code is not arriving, resetting the password uses the same delivery path and can lock the address out entirely. If sign-in is failing, reset is not the fallback. The front desk is.

Step 4: Sign in on one device and stay there

Reviewers report being kicked out for being signed in on too many devices at a threshold as low as two. If you have the app on a phone and a tablet, pick the one you carry to the gym.

Step 5: Check your billing the same week

This is the step people skip, and it is the one with a price attached. See the next section.

The Part That Costs Money

47 of the 169, 27.8%, mention billing, and one specific charge comes up again and again:

If you are even one day late or your payment method fails, it is automatically a $20 late charge every single time.

The reason this belongs in an article about sign-in is that the two problems meet. If you cannot get into the app, you cannot see that a payment method has failed, and the first notice you get is the fee. One reviewer describes doing everything right and being charged anyway:

After being notified that my payment information was incorrect before this week, I updated my bank info and made sure it was all correct. I also had a credit card on file. To my surprise this week, the app was unable to process either payment. I had to ask my gym to switch it to just my credit card so the payment could go through, but had to pay a $20 late fee because of the app.

Another describes the fee arriving after the payment was made in person:

It want accept the card that I have to pay my account. Then I go into the club and pay my account and it always sends me a notice about its late and its already paid.

We should be careful about the claim some reviewers draw from this, which is that backup payment methods are ignored deliberately. That is an accusation we cannot verify from review text, and we are not repeating it as fact. What the reviews do establish is the sequence: the app fails, the payment fails quietly, the fee is automatic, and nobody finds out until later.

Cancelling Is Not in the App, and That Is the Loudest Complaint Abroad

37 of the 169, 21.9%, mention cancelling, and the complaint is almost always the same: the app that took the signup will not take the cancellation.

Will not let me unsubscribe, I am being told to write a letter as the online and website resources and call resources will not help me.

The non-US storefronts are where this theme dominates. 11 of the 34 non-English complaints, 32.4%, are about cancellation, a much higher share than in the US set. A Spanish-language reviewer describes going to the club in person and still not getting out:

Spanish

no me deja cancelar mi membresia fui a mi club para pedir el formulario de cancelacion no me lo quieren dar

Another Spanish-language reviewer is generous about the rest of the app and stops at the same wall:

Spanish

lo único que no me gusta es que para cancelar la suscripción / membresía tienes que ir a las instalaciones

And a French-language reviewer in Canada describes the phone line as the third dead end:

French

imposible de se désabonner, je vient d appeler et il ne reponde pas a 8.25pm aucun lien email sur leur page web

Before you sign up anywhere, this is the thing to check, because the reviews suggest cancellation terms vary by club. Ask your home club how cancellation works and get the answer in writing while you still have the leverage of not being a member yet.

The sign-in problem shows up in the same non-English reviews, which is the cleanest evidence that it is not a US network quirk:

Spanish

Llevo 2 meses inscrita al gimnasio y no he podido abrir mi sesión en la aplicación siempre me pide el correo y el código pero por mas que los pongo siempre carga y se traba

The Crowd Meter Reads Low, and the Check-In Problem May Be Why

11 of the 169, 6.5%, say the crowd meter is wrong, always in the same direction. It reads empty when the gym is full:

When you need body armor just to fight your way through the door, the crowd meter says it is half empty.

It only gave 3 bars so I assumed the gym would not be busy. I get there and there was zero floor space for stretching and none of the machines I needed were available, it was so incredibly busy.

I've noticed the crowd meter never seems to go above 3 bars regardless of the amount of people that are there.

Here is the part reviewers have not connected, and we are putting it forward as a hypothesis rather than a finding. The crowd meter has to be counting something, and the obvious thing to count is check-ins. Meanwhile this same review set is full of members who cannot check in through the app and are being processed at the desk instead, or waved through on a temporary barcode. Every one of those members is in the building and, quite possibly, not in the count.

There is one review that hints the staff understand the dependency, even if the wording is exasperated:

staff complained about using a screenshot due to the crowd meter nonsense that is never accurate anyways.

If that is what is happening, the meter is not lying so much as counting a shrinking share of the people who walk in. It would also mean the two complaints are the same complaint, and that fixing sign-in would quietly fix the meter.

The App Also Just Stops

16 of the 169, 9.5%, describe the app failing to load at all, which is separate from the sign-in loop because these reviewers are already signed in:

my app and qr code loaded the first day but after that it just brings me to the loading screen and nothing loads. I’ve waiting for 20 minutes, updated the app, deleted it and reinstalled it and nothings working.

Reinstalling is the first thing almost all of them try, and it is not reported as working. For this group the desk check-in is not a workaround, it is the only route.

What These Reviews Are Not About

Gym reviews are usually a mix of software and everything else, so we count the everything else separately. 15 of the 169, 8.9%, are about the gym rather than the app: cleanliness, equipment, staff, opening hours, the person on the phone in the squat rack. None of them are counted in any cluster above.

That is a low share for a business with physical locations, and it points the same way the numbers do. People are not using the app store to complain about their gym. They are using it to say they cannot get into the building.

The Bottom Line

The Planet Fitness app rates 4.65 on Google Play and 4.87 on the App Store, both lifetime averages built over years. In the reviews written since late April, more than a quarter of the complaints are about a sign-in flow that emails a code and then stalls, and another quarter are about billing, including an automatic late fee that a broken sign-in makes it harder to see coming.

If the code loop is happening to you: ask the desk for a phone number check-in, stop hammering the reset button, and look at your payment method on a computer this week rather than next month.
