Carista OBD2 on iPad (4th gen)
iPad (4th gen) · 2012 · A6X · Max iOS 10 | Carista OBD2 requires iOS 16+
Carista OBD2 requires iOS 16. Your iPad (4th gen) maxes out at iOS 10 — a 6-version gap. Native install isn't possible, but the Safari PWA and alternatives below may help.
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 Carista OBD2 using the same Apple ID.
- On your iPad (4th gen), open the App Store → tap your profile picture → Purchased.
- Search for Carista OBD2. Tap the cloud icon.
- iOS asks: "This app requires iOS 16. 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 Carista OBD2 via Safari (PWA)
Many apps have a full web version accessible via Safari. Open Safari on your iPad (4th gen), 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.
