User Reviews

The app started as a promising passwordless Mac unlock concept for iPhone/Apple Watch, but is largely unusable today due to lack of updates, OS compatibility problems, and unreliable connections. Users report setup and Bluetooth issues, plus pricing/refund complaints. The core idea remains appealing, but persistent maintenance and compatibility issues have driven most users to abandon it.

Pros

Great concept for passwordless Mac unlocking.
When it worked, it unlocked quickly with a few taps.
The idea itself was appealing and could be a convenient solution.

Cons

No longer updated; development appears abandoned.
Incompatibility with newer macOS/iOS versions (e.g., High Sierra and beyond).
Unreliable or intermittent performance with slow or broken connections.
Setup/ Bluetooth issues and extra steps (e.g., needing to unlock the iPhone first).
Pricing and refund concerns (charges without permission; difficult refunds).

Recent reviews

I purchased the app and it only worked for a short time until it didn’t, I’m sick of looking at the app on my phone and watch and want to delete it and keep checking to see if it’s updated, and it’s not.

Developers dropped updates and further development of this app. At this point it needs to be pulled. Don’t waste your money as this won’t work for you.
