Do I need the App Store or Google Play?
No. High Performer Certs is a web app: you add it to your home screen from the browser, and it then opens full screen like an installed app.
There is nothing to download from an app store and nothing to update – the app is always the current version.
Is my progress the same on every device?
Yes. Your progress is stored in your account, so the installed app, the browser and your other devices show the same state.
Can I get reminders?
Yes, if you want them: in the app’s settings you can switch on one push notification in the evening, only on days you have not studied yet.
On iPhone, reminders need the app on your home screen first.
Does it work offline?
You need an internet connection to train, because questions and your progress are loaded live from your account.
