MatchShot

What it does

Most progress-photo apps align your shots after you take them, cropping, warping, still drifting. MatchShot aligns before the shutter. Drop a reference photo onto your live viewfinder as a ghost overlay, line up the shot, tap - today's photo is already matched to yesterday's. Built for pregnancy weeks, baby growth, fitness transformations, beard/skincare journeys, plant growth, and any "same shot, later" series. On-device AI Align. No accounts. No cloud. Free tier included.

MatchShot is the iPhone overlay camera built for series — pregnancy weeks, fitness transformations, baby growth, plants, travel returns. Reference photo lives on the viewfinder so every shot lines up before you press the shutter.

MatchShot is the overlay camera built for series — pregnancy weeks, fitness, baby growth, plants, travel returns. Drop in a reference photo. The shot you took yesterday becomes a soft ghost on today's screen. Line up the eyes, the doorframe, the horizon. Tap the shutter. Today's photo is already aligned to yesterday's — no cropping, no AI guessing, no remembering where you stood. Eight starter themes baked into the app. Or roll your own — drop any photo as a reference and start a Collection. One photo a week, perfectly aligned. End the nine months with a story you can scroll through in seconds. Same chair, same teddy, every birthday. The overlay does the lining up so your kid doesn't have…from matchshot.s10n.app

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
