Evidence when the moment matters

You have access to the last hours and days, even if you did not record anything manually.

Instant moment recovery

Open the app, go back to the selected moment, and save exactly what you need.

Privacy without compromise

Recordings stay on your device. You decide what to save and what to delete.

Why Witnessy

A modern tool for documenting what cannot be predicted

Instead of relying on luck, you have a system that runs in the background and lets you return to important moments when you truly need them.

Core feature

Loop recording of the last 3 days

The app continuously keeps the latest part of your audio history. When something important happens, you can go back to a specific moment and save it permanently.

Runs in the background
You do not have to remember to start recording manually.
Save only what matters
You archive selected fragments instead of storing everything forever.
Convenience

Intuitive to use

Pick a time, listen to the moment, and save it to your archive. No complicated steps.

Control

Complete user privacy

Your files stay on your phone, so you remain in control of access, deletion, and storage.

How it works

4 simple steps to secure important moments

The whole process is designed so you do not have to react instantly. Witnessy works beforehand, and you return to the moment later.

Important on Android: for stable background operation, it is worth excluding the app from battery optimization. It is also a good practice to restart loop recording from time to time.
Step 1

Turn on listening

Once launched, the app starts recording audio in a loop.

Step 2

Use your phone normally

Witnessy runs in the background, so you do not have to keep the app open on screen.

Step 3

Go back to a specific moment

When something important happens, open the app and return to the selected time.

Step 4

Save the clip permanently

The selected material goes to your archive, where you can manage it easily.

Best practices

How to keep loop recording running reliably

To help Witnessy run as reliably as possible in the background, it is worth applying a few simple settings and habits.

1

Exclude the app from battery optimization

System power-saving mechanisms may stop the app from running in the background.

2

Turn off “Manage unused app”

In the system app settings, disable this feature so Android does not automatically restrict Witnessy.

3

Restart loop recording at least once a week

This is a good practice that helps keep the app stable over longer periods of time.

4

Disable automatic updates

An automatic app update may interrupt loop recording at the worst possible moment.

5

Remember that restarting or turning off the device disables the loop

After restarting the phone, loop recording must be activated manually again.

Important

Performance stability also depends on Android

Different phone manufacturers use their own power and background app management mechanisms. That is why additional system settings may be crucial on some devices.

Check battery settings
Make sure Witnessy is not being restricted by power-saving mode.
Check how it behaves after restart
After restarting your phone, verify that loop recording has been activated again.
Good practice
It is best to treat Witnessy as an app that should be consciously kept active in the background.
