ALIGNCAM is a camera built for one thing: getting the next photo to line up with the last one. Repeat photography, stop motion, growth records, product reshoots — anything where every frame has to match. ONION SKIN The previous photo sits semi-transparent over the viewfinder. Line it up, then shoot. Pick any photo as the reference, flip its orientation freely, and match the same angle and framing on the first try. STEP SEQUENCE Give a guide circle a direction and a step distance. Every time you press the shutter, the guide advances one notch — a track to shoot stop-motion and displacement sequences along. Adjustable ghost count, step back to reshoot, resume after a break. GUIDES Thirds, halves, multi-cell grids, golden ratio, spiral, diagonals, plus your own lines and circles. Eight scene slots remember a whole set-up and switch between them in one tap. Level snapping keeps things straight whether you hold the phone upright or sideways. STRAIGHTEN WHILE SHOOTING The perspective pad corrects while you frame: pull a tilted building upright, square up a poster shot from the side. What you see is what you get, with nothing to fix afterwards. FILM FILTERS AND CONTROL PAD Eleven film recipes preview live and are baked in when you shoot. The pad beside the shutter controls temperature and saturation with one thumb, or switches to focus — drag to focus where you want. EDIT ROOM Draw two lines to straighten perspective (the whole canvas warps; the surroundings stay). Remove white edges while keeping the ratio. Crop to the viewfinder ratio. The result can go straight back in as an onion-skin reference. FLIPBOOK Pick a batch of photos and string them into a stop-motion clip. Speed curves, hold on the first and last frame, four click sounds, and a wheel where you can see the rhythm frame by frame. Export straight to your photo library. Every photo and setting stays on your device. No account, no tracking, no network needed.
