Method 1: Install the Last Compatible Version
Apple's App Store has a hidden feature: if you've ever downloaded an app on any device with the same Apple ID, you can install the last version that supported your iOS.
- On a current iOS 16+ device (friend's phone, family iPad), download Penbook: Paper Planner & Notes using the same Apple ID.
- On your iPad Air 2, open the App Store → tap your profile picture → Purchased.
- Search for Penbook: Paper Planner & Notes. Tap the cloud icon.
- iOS asks: "This app requires iOS 17. Download last compatible version?" — tap Download.
✅ This works for most major apps as long as you've previously installed them with this Apple ID. The older version connects to the same servers — your account and content remain accessible.
Method 2: Use Penbook: Paper Planner & Notes via Safari (PWA)
Many apps have a full web version accessible via Safari. Open Safari on your iPad Air 2, go to the app's website, sign in, then tap Share → Add to Home Screen. This gives you a home screen icon that opens the web app in full-screen mode — no download required.
