GridFix vs Plumb.cam

Tilt your camera up at a building and the verticals lean inward. Let your hand tip and the horizon goes crooked. GridFix fixes this the most intuitive way possible: draw guide lines along the edges that should be straight, and the app computes the perspective correction that makes them truly vertical and horizontal. And now, you can get it right at the moment you shoot. LIVE-CORRECTED CAMERA - The corrected image shows live in the viewfinder. What you see is what you get, no guesswork afterwards - A tilt readout shows your pitch and roll at all times - Correct verticals only, or auto-level the horizon as well - Pinch to zoom, EV compensation scale, long-press AE/AF lock, self-timer, volume-button shutter - Level sensor calibration: a fixed offset from your case or sensor tolerance is measured once and subtracted from then on - The session gallery lets you review shots, compare with the original, or send one straight into the editor EDIT IMPORTED PHOTOS - Guide-line correction: no blind slider fiddling, just show the app which lines should be straight - Double-tap to zoom: magnify right where you are working and trace window frames and beams precisely - A loupe keeps the edge visible while you drag, positioned for right- or left-handed use - Lens distortion correction: fixes the outward bow of ultra-wide edges, which perspective correction alone cannot fix - Fine-tuning: adjust every axis manually after the correction - Crop, rotate, flip, and auto-trim the blank edges correction leaves behind - Edit history: every session is saved automatically, so you can reopen and continue any time IMPORT AND EXPORT - Import from Photos, Files and iCloud Drive, or share into GridFix from any other app - Export JPEG, HEIF, PNG or TIFF, at original resolution or a custom size - Everything runs on your device: no account, no network, your photos never leave your phone FREE AND SUBSCRIPTION Every correction tool is free: guide lines, lens distortion, fine-tune sliders, cropping and the live-corrected camera are all fully usable, with unlimited viewfinder time. The limits are only on output: 3 editor exports a day, 10 camera saves a day, both at up to 2048px on the long edge, JPEG, without capture info or location (the capture date and orientation are kept). Subscribing unlocks: - Unlimited exports and unlimited camera saves - Original-resolution export (up to 48MP; the free tier caps the long edge at 2048px) - RAW import (ProRAW, DNG); PNG, TIFF and HEIF export at maximum encoder quality - Full EXIF kept on exports and captures (lens, exposure, location) - Live-corrected video recording (high-bitrate HEVC) GridFix does one thing well: it makes crooked lines straight. No color grading, no filters, no object removal. Available in English, Traditional Chinese, Simplified Chinese, Japanese, Korean, German, French and Spanish.

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.
