EchoShot Camera vs Time Flow Sketch

Take a photo while overlaying a previously taken (or chosen) photo on the camera preview. Useful for taking photos with the same angle of view as old photos, or for puppet animations/stop motion. The overlay can be displayed in three different ways: semi-transparent, outline, or pulsating (crossfade). Version 2.0 adds multiple exposure (blend several shots into one photo), a self-timer with an on-screen countdown, a square aspect ratio option for both the live preview and the saved photo, and optional location tagging for saved photos. No ads, no in-app purchases — everything is included with a single purchase.

A sketching app for reshaping the way time flows inside a video. You draw the shape of that flow as a black-and-white gradient over the clip you loaded. The brightness you paint becomes a moment in the clip, or a playback speed, so different parts of the image start running on their own time. Only where your finger traced runs ahead. Another part plays backwards. One area stays frozen while everything around it keeps moving. You can even draw time that twists — forward and backward unfolding at once. Take the single, even flow of time in a video, pull it apart, and put it back together. Reflections shifting on water, drifting clouds, the movement of familiar things and creatures: there may be something new waiting in the everyday scenery you thought you knew. ■ Main features [Making a map] • Draw — trace with a finger to draw the flow of time. Five brush tones, a bleed brush, and a smudge tool • Gradients and presets — start from a regular pattern • From motion — build the shape of time automatically from the movement in the clip • Cut & slide — split the map along a line and slide the pieces to make time slip [How the map is applied] • Apply mode — Vertical / Horizontal slit works band by band, Surface works pixel by pixel • Time map — brightness sets which moment of the clip is shown; black is the start, white is the end • Rate map — brightness sets the playback speed, from reverse to fast forward • Space map — brightness sets where on screen the picture is taken from [Checking what you made] • 3D plot — see the shape of time as a solid • Time graph — see time, rate and space as line charts [Live camera] • Time-shape the camera image as you film — it keeps the last few seconds, so the map you draw can show the past or freeze parts of the picture • Tap “Stop & capture” to turn it into a clip you can edit and export [Sound and export] • Sound — the audio goes through the same time processing as the picture • Export — save the result to your photo library as a video All video processing happens on your device, and nothing you make is sent anywhere.
