April vs Collage Pro

April is a photo collage app for Android and iOS that combines images with layouts, stickers, presets, and editing controls. It can select photos from a camera roll or other albums, and portrait recognition is intended to keep the chosen subject in place. Collages can contain one to nine photos in square, portrait, or landscape layouts, with sections resized by dragging. Users can adjust border width, color, texture, margins, and corner degree, then rotate, mirror, flip, or zoom photos. More than 40 filters are available, with controls for effect strength. Stickers and customizable tiles can add time, date, city, and weather. PicStrip offers full-view and large-view previews while users adjust individual images in the wider collage. April supports JPG and PNG exports and says it integrates with Instagram and Facebook for one-tap sharing. The app is free, with a monthly April VIP subscription at $1.99 a month. April is intended for personal, non-commercial use unless separately agreed with Pinguo.

Collage Pro is a web-based editor for combining images into photo collages, social image grids, product visuals, and long stitched images. Its collage editor accepts 1–16 photos, with more than 100 preset grids, a custom layout builder, free placement, and text overlays. Editing controls include cropping, zooming, rotation, repositioning, spacing, corners, borders, and backgrounds. Long Image mode stitches images horizontally or vertically, supports batch upload and reordering, and has no fixed item limit, although stable exports are recommended under 50 images. PNG, JPG, and WEBP exports offer quality settings from 0.1 to 1.0. Editing and export run locally in the browser, while projects can be saved in the current browser through IndexedDB rather than cloud storage. The responsive app works on phones, tablets, and desktop browsers.
