liviGrid

LiviGrid bundles several photo utilities in one app. Live Photo Puzzle combines one to nine Live Photos into a single puzzle where each photo keeps its animation, with layouts such as 2x2, 3x3, side-by-side and top-bottom, canvas ratios from 1:1 to 16:9, adjustable spacing, corner radius and background color, and a custom cover frame. Video to Live Photo trims a three-second clip from any video with a visual timeline and saves it to the album.

The Image Grid Splitter cuts a picture into seven grid layouts and six crop ratios, with the pieces saved in posting order for social media, and Long Image Stitch joins photos horizontally or vertically for travel logs or recipes. Processing is entirely local, no watermark is added and the app supports English and Chinese.

LiviGrid is available for iPhone and iPad and is free to download with in-app purchases. Memberships are listed as $1.99 monthly, $4.99 quarterly and $14.99 annually, and the developer states that it does not collect data from the app.
