MomentBack Replay Camera

Replay Camera · Android

Save the moment. After it happens.

You are always late to the record button. MomentBack keeps the last seconds the camera has already seen, so the clip starts before you reacted.

MomentBack's camera screen over a photo of a dog running through shallow water at sunset. A chip at the top counts the seconds being held up to 30, then reads READY · 30s. At the bottom, the replay lengths 15s and 30s, then 60s and 120s with a Pro lock, above the large orange SAVE button.

The whole app, in three verbs

Hold, save, share

  1. 01 Hold

    Open it. It is already holding.

    Opening MomentBack arms the camera. The last 15 or 30 seconds are kept on the device and continuously replaced by newer ones — not a file, not in your Gallery.

  2. 02 Save

    Press SAVE after the fact.

    SAVE keeps everything already held and keeps filming until you press STOP. The clip starts before the thing you reacted to.

  3. 03 Share

    It is a normal video now.

    One MP4 in Movies/MomentBack on your phone. Share it from Clips through Android's share sheet, or delete it there.

How it works

One press, two directions in time.

There is no session to start and no red button to remember. The camera arms itself, and the only decision left is whether the last few seconds were worth keeping.

A time axis. A band marks the last seconds continuously held on the device. A marker after the event marks the SAVE press, and the saved clip spans backwards across the held seconds and forwards to STOP.

SAVE reaches back across the held seconds and forward to STOP.

Inside the app

Six screens from the app.

Pick a label to switch the screen. The interface is always the real app; in the first three, the scene in the viewfinder is a stock photo.

MomentBack's camera screen in Turkish, over a stock photo of a dog jumping at sunset: a teal HAZIR · 30 sn chip at the top, the 15, 30, 60 and 120 second rail with locks on 60 and 120, and the orange KAYDET button. The camera screen moments after opening, over a stock photo, with the chip reading 2/30 sn while the replay window fills. The camera screen after SAVE, over a stock photo: an orange KLİP 0:31 chip, a confirmation reading that the last 30 seconds were kept and recording continues, and the round STOP button. The Klipler sheet listing saved clips with their date, size and length, each with share and delete buttons. The Ayarlar sheet: replay length, a Record audio switch, video quality, MomentBack Pro marked locked, restore purchases, and turn off camera and microphone. The video quality sheet: Efficient 720p 30 fps selected, Standard 1080p 30 fps, Smooth 1080p 60 fps marked not supported by this camera, and High resolution 4K 30 fps, the last two with a Pro star.

The chip — READY · 30s, shown here in Turkish — means the last 30 seconds are held. 15s and 30s are free; 60s and 120s carry a Pro lock. Interface from the app · scene in the viewfinder is a stock photo

Right after opening, the chip counts what is really held — 2/30 here. SAVE keeps whatever is already there; it never promises seconds it does not have. Interface from the app · scene in the viewfinder is a stock photo

SAVE kept the last 30 seconds and recording carries on. The chip turns orange and counts the clip; the round STOP button finishes it. Interface from the app · scene in the viewfinder is a stock photo

Everything MomentBack saved, with length, date and size. Share straight to another app, or delete.

Replay length, sound on or off, video quality, Pro and restore — and one control that turns the camera and microphone off.

720p and 1080p at 30 fps for everyone. 1080p60 and 4K30 are Pro, and only where the active camera supports them — this one has no 60 fps, and the row says so.

Captured on a Samsung Galaxy M21 (Android 12) from the 2–3 October 2026 test builds, in the app's Turkish interface — MomentBack ships in 11 languages. The phone's status and navigation bars are cropped out and no control was altered. The test captures had a dark viewfinder, so in 01–03 a photo by Filip Mavrodiev (Unsplash) is laid in behind the interface.

Moments

The moments nobody records in time

None of these announce themselves. They are over in the second it takes to find a button, which is the entire reason this app exists.

  • A corgi leaping across a lawn to catch a frisbee.

    Kids and pets

    The first step, the jump off the sofa, the face they will never make again on request. By the time you have the camera recording, you are filming the aftermath.

  • A skateboarder in the air above a skate park bowl at sunset, onlookers in silhouette.

    Sport and speed

    Skateboarding, cycling, fishing, the one run that finally works. Keep the camera up through all of it and decide afterwards which seconds were the good ones.

  • Forked lightning striking behind a line of trees under a lit storm cloud at dusk.

    Outdoors and the unexpected

    Lightning, wildlife, a wave, something falling over. You cannot predict the instant, so stop trying — hold the camera and reach for SAVE when it is already over.

Privacy

Nothing leaves the phone

A camera that is always watching has to be honest about where the picture goes. This is what MomentBack does, taken from the app's own source.

  • Nothing is saved until you press SAVE

    The held seconds live in the app's private storage, are overwritten continuously, and are discarded when capture stops. They never appear in your Gallery and no other app can read them.

  • Clips are files on your phone

    SAVE writes one MP4 into Movies/MomentBack in your Gallery. From there it is an ordinary video: yours to keep, share or delete.

  • No account, no server

    No sign-in, no profile, no identifier, and no MomentBack server to send anything to. There is no analytics SDK, no crash reporter and no advertising code. The one outside service is Google Play's billing, used only for the optional Pro purchase.

  • The microphone only when sound is on

    Record audio is a switch in Settings. Turn it off and MomentBack uses the camera alone: the microphone is never opened and saved clips carry no audio track.

Questions

Straight answers

Does MomentBack save to my Gallery all the time?
No. While capture runs, the last seconds are held inside the app's own private storage and are continuously overwritten. A file appears in your Gallery only when you press SAVE. Stop without saving and the held seconds are discarded.
Do I need internet or an account?
No account, ever. Holding, saving, Clips and sharing all work offline, in airplane mode too. The only thing that needs a connection is buying or restoring Pro, which Google Play handles.
Where are clips saved?
In your device Gallery, in a Movies/MomentBack album, as standard MP4 files. The Clips screen inside the app lists the same files. MomentBack can only see the videos it created itself — it never asks to read your photo library.
Can I record without sound?
Yes. Turn off Record audio in Settings. MomentBack then never opens the microphone, does not need microphone permission, and saved clips have no audio track.
Does keeping the camera open drain the battery?
Yes, and we would rather say so. The camera and a hardware video encoder run the whole time capture is armed, and the phone can get warm; 1080p60 and 4K use more than 720p. Capture keeps running when you switch apps or lock the screen, with an ongoing notification that has STOP and QUICK SAVE actions. When you are done, stop it.
What does Pro cost, and what does it unlock?
Pro is a one-time purchase with no subscription. It unlocks 60 s and 120 s replays, and 1080p60 and 4K30 on cameras that support them. Its price will be shown by Google Play; MomentBack is not on sale anywhere yet.
