FrameCat is a Frame Catcher. It captures screenshots at the video's original resolution, so you do not have to rely on ordinary phone screenshots. It supports landscape and portrait videos, single-video captures, and multi-video frame capture. Save one frame at a time, or stitch your captured frames into one long image after you finish. FrameCat's touchpad-style control helps you move to the exact frame you want, then tap lightly to capture it with confidence.
Plumb.cam
Read full descriptionHide full description
Plumb is a perspective correction camera for architecture, interiors and the spaces you discover. Create a separate corrected photo using camera and motion information recorded at the shutter, while preserving the original. STRAIGHTER LINES, ORIGINALS PRESERVED Automatic correction helps reduce leaning verticals as you shoot. Compare Original and Corrected versions and choose what to save. Results depend on capture conditions; if a safe correction cannot be made, your original is preserved. ONE SHOOT, ONE ALBUM Current Shoot appears after your first photo. Create an album for that visit or add the session's photos to an existing album. Browse your Library in a grid or masonry layout. LOCAL FIRST Photos and correction processing stay on your iPhone unless you choose to sync or share. Choose what to save to Apple Photos, use the system share sheet, and optionally record locations. No advertising or cross-app tracking. FREE AND PLUMB PRO Free access includes 10 successful saves of distinct corrected photos per calendar month on this device, resetting monthly in UTC. Failed saves and repeat saves of a counted photo do not use another allowance. At the limit, automatic correction turns off; original capture and existing local photos remain available. Pro removes this allowance and adds optional iCloud Library sync, subject to your iCloud storage and Apple service availability. Choose monthly, annual or a one-time lifetime purchase.
