EnglishCrookCatcher Free vs Pro: What's the Difference?
Updated
CrookCatcher's free tier covers the core job: when someone enters a wrong PIN, pattern, or password, it takes a front-camera selfie, records the location, and emails both to you. Pro adds stronger evidence (video with sound, back camera, Google Drive backup) and active countermeasures (alarm, lock-screen warning, fake home screen, app lock). Choose free if you only want to know who tried to unlock your phone; consider Pro if you need evidence that holds up better or want tools to fight back while the phone is still in the thief's hands.
What the free version includes
According to the site, "everything you need to catch an intruder is free." The free tier covers:
- Intruder selfie — front-camera photo triggered by a wrong PIN, pattern, or password
- GPS location — location recorded with every alert
- Instant email alerts — photo and location sent straight to your inbox
The site also states CrookCatcher is free on Android with no registration, and cites 4.6 stars from 90K+ ratings, 12M+ downloads, and use since 2014. Every attempt is saved as a timeline with time and location stamps, and events are labeled so you can tell a failed unlock from a break-in.
What Pro adds
Pro is split into two kinds of upgrades: better evidence, and ways to respond.
Stronger evidence
| Feature | What it does |
|---|---|
| Video with sound | Captures voice and movement for stronger proof |
| Break-in detection | Still alerts you if the person guesses the correct unlock after failing |
| Back camera | Shows surroundings, not just the intruder's face |
| Google Drive backup | Saves evidence off-device automatically, even if the phone is gone |
Countermeasures
| Feature | What it does |
|---|---|
| Loud alarm | Startles thieves and alerts people nearby |
| Lock screen warning | Shows a message when an alert is triggered |
| Fake home screen | Tricks thieves into thinking they unlocked the phone |
| App lock | Pattern-locks CrookCatcher so it can't be disabled |
How to decide
The dividing line is what you plan to do with the evidence.
- Stay on free if your goal is simply to see who tried to get in and where they were — a photo, a location, and an email cover that.
- Consider Pro if any of these apply:
- You want proof that is harder to dispute (video with sound, back-camera context).
- You worry the thief will eventually guess the right unlock — break-in detection covers that gap.
- You want the evidence to survive losing the phone — Google Drive backup is the only off-device option listed.
- You want to act while the phone is still with the thief — the alarm, lock-screen warning, fake home screen, and app lock are Pro-only.
A practical way to test it
Install the free version first and confirm the basics work on your device: trigger a wrong unlock, then check that the selfie and location arrive in your email. If the free alert reaches you reliably, you've validated the core mechanism — Pro builds on the same trigger, so the upgrade is about evidence quality and response tools rather than a different detection system.
One caveat worth noting: the site does not publish pricing for Pro, so check the app listing for current cost before deciding. The feature split above is what the site documents; anything beyond that isn't confirmed here.
