How to Buy Pro (iPhone)
You can upgrade to Pro inside the StrongLifts app.
- Make sure you have the latest app version installed - https://itunes.apple.com/us/app/stronglifts-5x5-workout-log/id488580022?mt=8
- Open StrongLifts on your iPhone/iPad. Go to settings – account – StrongLifts Pro subscription.
- Choose Upgrade. Choose your plan, and follow the steps on the screen
Done. You’ll get access to all the StrongLifts Pro features after that.
The subscription amount will be charged to your iTunes account when you upgrade. Unless you turn off auto-renewal 24 hours before the end of your subscription, it will renew automatically for the same price, and your iTunes account will be charged accordingly. You can easily manage your subscription and turn off automatic renewal in the account settings for your Apple ID.
Note that the price of StrongLifts Pro depends on your location, currency and taxes. But the yearly fee is about the same as what you'd pay for one small tube of whey protein. To see the exact price, go to settings - account - upgrade.
If you don't like/want subscriptions, a lifetime one-time payment is also available. It's the most cost-effective option if you're serious about lifting and plan to do it for years.
