Two apps, one idea
Built for the way each platform works
Mac and Android handle defaults very differently. Each Defaultify app is native to its platform and goes as far as the system allows.

- Audit which apps handle PDFs, media, archives and code
- Deep link and intent inspector for
mailto:,tel:,geo: - Alerts when another app changes your defaults
- Health score, profiles and backups
Features
Everything about your defaults, in one place
Every file type and link
Documents, media, archives, e-books, code, 3D models, maps, plus browser, email and calling links.
Health score
See at a glance which types have no default, no app at all, or point at an app you deleted.
Profiles
Switch a whole set of defaults at once: Work, Privacy, Media, Developer, or your own.
Backups
Save your setup and put it back after trying a profile, installing apps or moving to a new device.
Change alerts
Get notified when another app takes over your browser, email or file defaults. On Mac, revert it in one click.
Link inspector
Find out which apps are registered for mailto:, tel:, geo: and web links before they open.
Default Guard on Mac
Your defaults stay yours
Installers and app updates quietly claim file types. You find out when a .json file suddenly opens in Xcode.
- Pin the defaults you care about
- Defaultify checks in the background and whenever an app launches
- One click puts things back, with a backup taken first
.json default changed
Xcode replaced Visual Studio Code. Revert to keep Visual Studio Code.

FAQ
Questions
Why does my Mac ask me to confirm each change?
Since macOS 26.4, Finder asks you to approve every change to a file-type or browser default ("Use … / Keep …"). That's a macOS safety feature, so no app can change your defaults behind your back. Defaultify shows each change as pending until you answer.
Why isn't the Mac app on the Mac App Store?
Mac App Store apps must run in Apple's sandbox, which blocks changing link handlers such as mailto:. To support every file type and link, Defaultify for Mac is a direct download, signed and notarized by Apple.
Does Pro on Android also unlock the Mac app?
Not yet. Pro is bought separately on each platform: through Google Play on Android, and on this website for Mac.
Does Defaultify collect my data?
Your defaults, profiles and backups stay on your device. The Mac app has no ads or analytics. The free Android app shows ads through Google AdMob; Pro removes them. Details are in the privacy policy.
Which versions are supported?
Defaultify for Mac needs macOS 14 Sonoma or later and runs natively on Apple silicon and Intel Macs. Defaultify for Android is available on Google Play.
