留痕 vs Comparison Camera

留痕：对齐拍照，记录真实变化。 健身体型、装修/手作进度、孩子宠物成长、植物生长——每天一张，一眼看见进步。 照片仅保存在你的设备中：不上传、不社交。 你可以用留痕记录这些变化 • 健身 / 体型变化：同角度进度照，看到自己一点点变好 • 装修 / 手作项目：工程推进、细节完成度，按天留下证据 • 孩子 / 宠物成长：从某一天开始，时间会给你答案 • 植物生长：发芽、长叶、开花，把变化串成一条线 对齐拍摄，记录真实变化 打开相机后，上一张照片会半透明叠加在取景画面里。 你只要对齐位置，按下快门—— 每天一张，就足够。 时间轴浏览，一眼看见进度 所有照片按时间自动排列。 变化不需要解释，它会在时间里自然发生。 回看时，你看到的不只是照片，而是你做过的事、走过的路。 只属于你的记录 • 仅保存在你的设备中 • 不上传、不社交 没有打扰，没有比较，只为你自己留下痕迹。

Comparison Camera — Take before & after photos, generate comparison images in one tap. Record progress at the same angle for fitness, growth, skin care, plants, or anything you want to track. View every shot on a timeline, compare any two with side-by-side, slider, or overlay modes, then save the comparison image to your photo library or share it. Why Comparison Camera? ・ Built for before/after Organize by projects (e.g. "90-day cut", "succulent log"). Each photo lands on a timeline so you can pick any two and compare. ・ Align shots easily The first photo appears as a semi-transparent overlay in the viewfinder so you can match angle and framing for consistent, comparable shots. ・ Compare your way Side-by-side, slider, or overlay — see even small changes clearly. Generate a comparison image and save or share. ・ Your data stays on your device All photos and records are stored locally. Nothing is uploaded or collected. Who is it for? Fitness and weight loss, baby milestones, plant diaries, skin and hair progress, crafts and creations, pet growth — any journey where you want to see change over time. Download Comparison Camera and turn daily effort into clear before/after comparison images.
