Smile
Read full descriptionHide full description
You want to take a lot of pictures of your child's growth, especially cute smiles. However, a baby who couldn't understand the language doesn't laugh at all, and when finally laughed, I couldn't shoot in time. Also, when it takes time to shoot, children get sick and it's finally hard to shoot with a smile! Since I have twins, it's extremely difficult to take better pictures... In such a case, this app! When the specified number of people smile, pictures will be taken automatically. Even if no smile, eyes open, it's OK, you can also specify the number of people with open eyes for automatic shooting. It is also possible to shoot while playing youtube videos for children. * Screen description * Play button: Play the video Web button: Opens the home page (Tap an empty area to hide the panels and buttons.

Interval Camera takes photos automatically at preset intervals and saves them directly to Photos. Use a tripod for selfies, group portraits, craft projects or changes you want to record over time. Capture settings • Choose an interval from 1 second to 5 minutes. • Start-delay presets from 0 to 60 seconds. • Stop after 1, 5, 10, 20, 50 or 100 photos, after a set duration, or manually. • Pause a session and resume the remaining shots. Standard and Silent modes Select the capture mode in Settings. Silent mode saves a frame from the camera feed instead of taking a standard photo. Image quality and resolution differ from Standard mode. Flash, start sounds and countdown sounds are unavailable in Silent mode. Camera controls • Front and rear cameras, with zoom on supported cameras. • Tap to focus, pinch to zoom, AE/AF lock and exposure adjustment. • 4:3, 1:1 and 16:9 aspect ratios, grid and level. • JPEG/HEIF and available photo resolutions depend on the device and capture mode. Saving and reviewing View and share saved photos. If saving fails, retry saving the retained photos or explicitly discard only the failed photos. Already saved photos are kept. Keep the app visible and the screen unlocked while capturing. Processing and saving can delay the next shot. Check available storage before long sessions. This app takes still photos; it does not create timelapse videos or analyze movements. No ads or account registration. The app does not upload your photos. iCloud Photos syncing follows your device settings. For help, use the App Support link on this page.

Verdict
The clearest difference is price: Smile at Free against Interval Camera's $1.99. Smile also leads on device support (3 vs 1) and iOS requirement (14.3 vs 17.0). Interval Camera's advantage is ads (none vs shown). On in-app purchases there is nothing between them.
