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.
