Recording starts the moment you open the app. The time and place are stamped into your videos and photos, so you can prove when and where they were taken. Like a dash cam. Like evidence. A camera for moments you can't afford to miss. ■ Instant recording Open the app and it is already rolling. If a call comes in or you leave the app by accident, the recording is saved automatically. ■ NEW: Photos Switch to PHOTO below the preview and shoot with the shutter or a volume button, in 4:3, 16:9, 1:1 or 3:2. While recording, save the current frame as a photo without stopping. Each photo keeps its capture time and real GPS in the file. ■ NEW: Stamp cards Choose the classic timestamp line or a card with a large clock, date and your note, and preview each style on your current scene before you pick it. Add a map, address, coordinates, altitude, a bearing arrow that points north, and your logo. GPS off by a block? Pin the right spot: the stamp shows the pin, the file keeps the real GPS. With Precise Location off, the stamp shows your approximate area. The time on the stamp can never be edited. ■ NEW: Projects Keep each job, site or trip in its own project in the private album. ■ Split long recordings Save a file every 5 to 60 minutes without interrupting recording. ■ One tap from the Lock Screen (iOS 18 and later) Put FastCam on a Lock Screen button or in Control Center. One press and you are recording. ■ A timestamp burned into the video Written into the frames as you record, not a caption added later. Choose the font, 0 to 4 decimal places for seconds, the corner and the opacity. Real-time sync keeps the stamp correct even if your device clock is off. ■ Hands-free voice commands Say "Go", "Stop" or "Pause", or "Go" to take a photo. Set your own words, and use your AirPods microphone. ■ Quality on your terms · 4K, 60fps and high bitrate · H.264 or HEVC, stabilization, mirror mode · Front or rear camera (wide, ultra wide, telephoto) and zoom presets · Landscape recording, even with rotation lock on · Change the stamp, location and voice settings without stopping the recording · Dim the screen and keep recording ■ A private album only you can open Lock it with a passcode, or save straight to Photos. Step through videos frame by frame, save a frame as a photo, and share, save, move or delete several items at once. ■ FastCam Premium Some features need FastCam Premium: a monthly or yearly subscription (new subscribers may get a free trial where available) or a one-time lifetime purchase, charged to your Apple Account. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period; manage them in Settings > [your name] > Subscriptions. Got FastCam before version 1.5.0? You keep every feature, no purchase needed. ■ Your recordings never leave your device Videos and photos are never uploaded. No ads, no tracking across apps.
