Read full descriptionHide full description
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.

Verdict
The clearest difference is in-app purchases: Positive View at none against Darkplug's 1. Positive View also leads on iOS requirement (16.0 vs 18.6). On price, ads and device support there is nothing between them.
