How to use AIRec

Install AIRec and open it

Install AIRec from Google Play and open it. The Home screen shows a big record button and your recording setup (Resolution, Frame rate, Quality and Audio). Nothing needs an account or sign-in.

Run the setup check (one minute)

Open Settings → Reliability → Setup and health. It lists what AIRec needs and lets you allow each item with one tap:

• Notifications: shows the recording status and the Stop button. Android requires a visible notification while recording.
• Microphone: needed only to record your voice. Recording without audio always works.
• Floating ball (display over other apps): optional, lets you control a recording from any screen.
• Keep recordings alive: turn off battery optimization for AIRec so the phone does not end long recordings. On some phones (Xiaomi, Oppo, Vivo, Samsung) also allow AIRec to run in the background or autostart in the phone’s app settings.

Choose your recording setup

On the Home screen tap each row to change it:

• Resolution: Auto, or 480p up to 2880p. For most uses 1080p is perfect.
• Frame rate: Auto, or 24, 30, 60, 90, 120 fps. Use 60 for games and fast scrolling, 30 for lessons and slides.
• Quality: Data saver, Balanced, High or Ultra.
• Audio: No audio, Microphone, Internal audio or Internal + Mic.

Set up your voice

Open Settings → Microphone enhancement:

• Noise reduction: Off, Standard (steady noise), Strong (noisy rooms) or AI (cleans after you stop and also reduces crying, animals, horns and sudden bangs, but saving takes longer).
• Echo cancellation: leave on Auto so the phone’s speaker sound is not recorded twice.
• Voice enhancement: Natural, Clear or Studio.

Then open Settings → Audio → Test microphone, speak for 10 seconds and compare Play original with Play processed. If it is too quiet or too loud, change the microphone volume.

Pick video options (optional)

In Settings → Video choose the video format (H.264 works everywhere; H.265 makes smaller files) and the orientation. Choose Landscape for games.

Set the controls you like

In Settings → Controls you can turn on a countdown, a timed recording that stops by itself, Shake to stop, Stop when the screen turns off, the screenshot preview notification and Show touches (a dot where you touch; it asks for the “Modify system settings” permission).

In Settings → Floating ball choose the ball size and transparency, whether it hides while recording and whether it shows only when a recording starts or all the time.

Start recording

Tap the big red record button on Home. Android asks whether AIRec may capture your screen (it asks every time, for your safety). Allow it, wait for the countdown if you turned it on, then go to the app or game you want to record.

Control the recording

You can control the recording in four ways:

• Notification: pull down the notification and tap Pause or Stop.
• Floating ball: tap it to open the menu with the timer in the middle and Pause, Stop, Draw and Screenshot around it. Drag the ball anywhere, or drop it on the X to hide it until the next recording.
• Shake: shake the phone to stop (if turned on).
• Quick Settings tile: start from the tile in your quick panel.

Use Draw to annotate live with the pen, smart-shape pen, highlighter, box, circle, arrow or line. Use Screenshot to grab a still image.

Stop and save

When you stop, AIRec finishes the video. You see a percentage in the record button, in the notification and in a window that appears over whatever app you are in. When it is done, the window offers Play, Share, Edit and Delete (Delete asks you to confirm), plus a one-line performance summary.

The video is already in your gallery, in the Movies folder inside a folder named AIRec.

Find and manage recordings

Open the Library tab. Videos and Screenshots have their own tabs. Tap a video to play it, or open its menu to share, rename, edit, see details or move it to the trash. Items in the trash can be restored for 30 days (Android 11 or newer).

Edit your video

Open the Edit tab, choose a tool and then a video:

• Trim: keep only the part you need.
• Cut middle: remove a section from the middle.
• Smart silence removal: cuts long pauses automatically.
• Speed: slow motion or fast forward (audio is removed).
• Merge: join two recordings made with the same settings.
• Remove audio: a silent copy.
• Extract audio: saves the sound as an .m4a file in Music/AIRec.

Edits never change your original. The result is saved as a new file.

Check the performance report

Tap Performance in the saved-recording window or open Settings → Performance report. It shows the frame rate that reached the video, temperature and heat, battery used and AIRec’s own load, with tips. If the phone got hot or frames dropped, try 30 fps or a lower resolution.
