Darkplug is a darkroom timer and printing tool for iPhone. It lets you control your enlarger from your iPhone using a compatible Shelly smart plug on your local network. Built for film photographers and darkroom printers, Darkplug combines precise timing, guided workflows, and a red-on-black interface designed for darkroom use. The clean timer interface is designed to stay practical under safelight conditions, with large controls and minimal clutter. Darkplug+ unlocks advanced printing tools, including F-Stop timing, guided test strips, dodge and burn planning, split grade printing, guided paper developing, and reusable Dodge & Burn plan codes. The guided test strip workflow helps you build and run exposure tests in seconds or F-Stops, then apply your preferred result as the print time. The Dodge & Burn workflow helps you plan local exposure changes, review a generated print plan, and follow guided execution steps in the darkroom. Plans can be exported and restored later with reusable plan codes. Darkplug also includes a guided developing timer for developer, stop, fix, and wash, so printing and paper processing can stay in one focused app. To use Darkplug, connect your enlarger to a compatible smart plug, make sure the plug and your iPhone are on the same local network, enter the plug’s local IP address, and connect. No account login is required. No cloud backend or external web service is needed for core timer operation. Compatible smart plugs: Shelly Plus Plug S Gen2, Shelly Plus Plug UK Gen2, Shelly Plug S Gen3, Shelly Outdoor Plug S Gen3, Shelly Plug M Gen3, and Shelly Plug US Gen4.

A powerful photo editor designed with film in mind. Edit your everyday photos and camera RAW files, try the colour of real film on them, and turn film negatives into finished pictures, with each frame found, cropped and straightened for you. Everything happens on your device, with no account and no subscription. EDIT YOUR PHOTOS Choose Edit photos to bring in JPEG, HEIC, TIFF or camera RAW files from Files or Photos, several at a time. RAW files are developed from their sensor data, with any lens corrections they carry. Start with Auto, then adjust exposure, contrast, highlights, shadows, whites, blacks, clarity and dehaze. Set white balance, shape tone and colour with curves, fine-tune eight colour ranges with the colour mixer and grade shadows, mid-tones and highlights with colour wheels. Crop, straighten and correct perspective, reduce noise, sharpen, take out colour fringes and remove dust with the repair brush. TRY A FILM ON YOUR PHOTO Choose a film and see it on your own photo first. Natural films are modelled on real film stocks, with their grain and halation, and you can shoot them under or over and push or pull the development. Nostalgic films are softer and dreamier, for a light, airy feel. FIND YOUR LOOK Choose looks across colour, cinema and black and white, from natural palettes and cinema grades to selenium toning and lith prints. Browse them all on your photo and set each one's strength. BRING YOUR FILM TO LIFE Photograph your negatives with a camera and light source, import the scans and choose the film type. Glass Half Full finds the picture area, crops and straightens it, and converts colour or black-and-white negatives into positives. Convert one frame at a time or a whole roll at once. Choose a clean standard conversion, a lab scanner's look measured from real scans, or a print on photographic paper or cinema film. Slides have their own workflow too. WORK ON JUST ONE AREA Brighten a face, darken a distracting background or bring back a bright sky with masks. Draw linear and radial gradients, paint with a brush, or select by colour or brightness. Masks work on digital photos and converted film alike. FINISH IT LIKE A PRINT Add grain measured from real film scans, halation and a vignette. Put the photo on a strip of film with its edge lettering and frame numbers, or print it on paper, from cotton and baryta to newsprint, in soft window light. MORE TOOLS Lay photos and text across several slides for seamless carousel posts. Layer up to nine photos into a multiple exposure. Plan, time and log your film development, with times from the makers' data sheets. ONE PHOTO OR A WHOLE ROLL Edit single photos, keep film scans together in rolls and gather photos from anywhere in your library into folders. Mark picks and rejects, copy settings across a set and export in batches. Save your settings as recipes to reuse, or share them as files and recipe cards. KEEP YOUR ORIGINALS Edits are saved separately and never change your imported originals. Compare with the original at any time and undo any change. Export a JPEG to share or a 16-bit TIFF for further editing, then save it to Files or Photos, or share it. Back up your library as a ZIP archive and restore it whenever you need to. RAW support depends on your camera. On a Mac with Apple silicon, Glass Half Full runs as its iPad app, with mouse, trackpad and keyboard controls, zoom buttons and keyboard shortcuts. TRY IT WITH YOUR OWN PHOTOS Import and edit as much as you like for free, and export up to 12 photos at full quality with no watermark. Re-export those photos whenever you like, including in other formats. A one-time Full Unlock removes the export limit. One purchase covers iPhone, iPad and Mac with Apple silicon, with Family Sharing included. No subscription or expiry. I’m Sam, the developer behind Glass Half Full. If something gets in the way of your photographs, I’d like to hear about it. You can reach me through Help & about in the app.
