The best side-by-side photo app for both iPhone and Android is a free browser-based merge tool: open it in Safari or Chrome, upload your photos, and download the result. No app-store download or account needed.
1. A browser-based side-by-side tool (works on both platforms)
Because it runs in the browser, the same tool works identically on iPhone and Android. You get control over gap, background color, and exact layout, which most dedicated collage apps limit to preset templates.
2. iPhone's built-in Photos collage
Available directly in the Photos app without downloading anything extra. Limited to a handful of fixed layouts, and crops photos to fit them.
3. Google Photos Collage (Android and iPhone)
Built into Google Photos under Utilities on both platforms. Same trade-off as the iPhone collage tool: convenient, but fixed cells with cropping and no gap or background control.
4. Dedicated collage apps
Available on both app stores with more templates, stickers, and filters than a browser tool. Worth it if you want decoration on top of the layout, overkill if you just want two photos placed side by side.
