Acteevy is a progressive web app. You install it straight from the browser, no app store needed.
Android (Chrome, Edge)
Open Acteevy in your browser.
Tap the three dot menu.
Choose "Install app" or "Add to home screen".
iPhone and iPad (Safari)
Open acteevy.de in Safari – not from inside WhatsApp or Instagram.
Tap the share icon.
Choose “Add to Home Screen”. From iOS 18 on it sits behind the three-dot menu (“…” or “More”).
Important on iPhone: it has to be Safari. Opened from a link inside WhatsApp, Instagram or Chrome, the “Add to Home Screen” entry is missing – and Safari hides it in private browsing too.
Windows, macOS, Linux
Open Acteevy in Chrome, Edge or Brave.
Click the install icon in the address bar.
Confirm the installation – Acteevy opens in its own window.
Note: browsers do not support lock screen or home screen widgets. On iOS push notifications only work after adding the app to the home screen.
