Add Helperly to your home screen for a full-screen app experience and push notification reminders, from Account → Profile.
Visit your profile page and tap Install Helperly. Your browser will ask you to confirm — once installed, Helperly opens in its own window without browser chrome.
On iOS, push notifications only work once Helperly is installed to your home screen this way — Safari itself can't deliver them. On Android and desktop, you can turn on push notifications from a reminder's settings whether or not you've installed the app, but installing still gives you quicker access.
The installed app has no browser reload button, so it refreshes itself when you come back to it after a minute or more away — unless you're in the middle of filling in a form, so nothing you've typed is lost. To check for changes right now, scroll to the top of any page and pull down until the arrow flips, then let go.
