How to buy a pack or a single session

Buy a single session or a pack on Payments (web) or Wallet (app). You pay with Stripe in your browser, and credits arrive within seconds.

2 min readUpdated November 3, 2026

You buy sessions on the Payments page of your gym's portal or the Wallet tab in the app. Payment happens on Stripe's secure checkout page, where your gym is the seller, and the credits arrive on your balance within a few seconds. You can then book any open time.

Warning: Closing checkout before it finishes can result in no purchase being made. Always wait for Payment complete before you leave the page.

Before you begin#

  • Have a payment card ready. The checkout page shows the payment methods your gym accepts.
  • Check that your gym has switched on online payments. If not, you'll see a message saying so.
  • Compare options with Session packs vs memberships.

On the web#

  1. Select Payments in the portal menu.
  2. Find Session packs.
  3. Select Buy on Single session, or Buy pack on a pack.
  4. Enter your payment details on the Stripe checkout page and pay.
  5. Wait for Payment complete — credits added to your account on the Payments page.

In the Levflex app#

  1. Tap the Wallet tab.
  2. Find Session packs and tap Buy on the option you want.
  3. Pay on Stripe's checkout page, which opens in your browser.
  4. Wait for Payment complete back in the app, which shows your new balance.
  5. Tap Book a session to use your credits.

Common mistakes#

Leaving while the payment is processing#

Some payments take longer to confirm. If the app shows Payment processing, your credits appear as soon as it clears. You can leave the screen safely.

Thinking a cancelled checkout charged you#

If you see Checkout cancelled — no charge was made, nothing was taken. A pending authorisation on your card from an unfinished checkout drops off on its own.

Buying at the wrong gym#

Credits only work at the gym you buy from. Check the gym name at the top of the screen before you pay.

Troubleshooting#

  • Did you pay but see no new credits?
    • Yes
      Wait 1 minute and refresh. In the app, tap Check again. If the purchase still shows Pending after 10 minutes, contact your gym with the time and amount.
    • No
      Go to the next question.
  • Was your card declined?

Every purchase shows under Purchase history. Whether Stripe also emails you a receipt depends on your gym's payment settings.
