Features
Read full description

This is a fully free architectural photography app. No account, sign-in, subscription, or in-app purchase is required. Please test the app on a physical iPhone because the main features require a camera and device motion sensors. On first launch: 1. Allow Camera access for live preview and photo capture. 2. Allow Microphone access when testing video recording. 3. Allow Photo Library access to save and view captured media. Two-point perspective correction is enabled by default. Tilt the iPhone upward or downward to observe the real-time vertical perspective correction in the camera preview. The app includes Photo, Video, Time-lapse, Slow Motion, and Distance Measurement modes. Distance values are visual AR estimates for reference only and are not a replacement for professional measurement equipment. All photos and videos are processed locally on the device. The app does not upload or collect user media.

About

Plumb

Read full description

Plumb is an iPhone camera with real-time perspective-correction preview, built for architecture, interiors and urban spaces. See corrected framing as you compose, then capture a separate corrected photo while keeping the original. LIVE PERSPECTIVE CORRECTION, BEFORE THE SHUTTER Turn on live correction preview to see how vertical lines and framing change as you move your phone. Compose building façades, interiors and street scenes before capture, then compare the original and corrected photos. Results depend on capture conditions; when a safe correction cannot be made, the original is preserved. RAW CAPTURE AND CORRECTED DNG EXPORT Capture 12MP/48MP RAW on supported devices and lenses. With correction on, export a corrected Linear DNG; with correction off, export the camera RAW for editing in compatible software. Editing inside Plumb applies to the non-RAW copy. FIND YOUR COLOR AS YOU SHOOT Swipe through live filters to preview the look before capture. Explore built-in styles including Classic, Morandi and Cool Tone, or create your own with curves, HSL and color grading. Try random color generation for inspiration, import compatible LUT files, and pin your favorites for easy access. EDIT FREELY. PRESERVE THE ORIGINAL. Crop, adjust perspective and color, or change filters after shooting. Edits are saved separately without overwriting the original photo or its capture information. Compare the original and edited result, view shooting parameters and edit details, and choose which original, corrected or edited version to save or share. ONE VISIT, ONE ALBUM Use Current Shoot to organize a session, create an album or add photos to an existing one. Browse your Library in a grid or masonry layout, and sort albums by recent updates or creation time. Exported photos automatically use filenames containing the capture time for easier archiving and sharing. LOCAL PROCESSING. YOUR CHOICE. Photos and correction processing stay on your iPhone. Your Library is stored locally by default; choose to save to Apple Photos, share, or enable iCloud Library sync with Plumb Pro. No Plumb account required, no ads and no cross-app tracking. FREE ACCESS AND PLUMB PRO Try automatic perspective correction for free, with an allowance for saving corrected photos. Upgrade to Plumb Pro to remove that allowance and unlock iCloud Library sync. Choose a monthly or annual subscription, or a one-time lifetime purchase. Prices are shown before purchase. Monthly and annual subscriptions renew automatically and can be managed or canceled in your Apple Account settings. iCloud sync requires available iCloud storage.
