Gridlai makes beautiful photo grids on your iPhone — simply, and privately. Pick 4 to 12 photos and Gridlai arranges them into a clean grid, ready to save and share. Everything happens on your device: no accounts, no uploads, no data collected. AI AUTO-ARRANGE — 100% ON YOUR DEVICE One tap and Gridlai arranges your photos and frames each one toward its subject, so faces stay centered and nothing important gets cropped out — then leaves every photo fully adjustable, so you can pan and zoom to fine-tune the framing. The AI runs entirely on your iPhone using Apple's on-device Vision technology — your photos are never uploaded, never sent to a server, never seen by anyone but you. FEATURES • Smart auto-arrange with on-device face & subject framing — and fully adjustable after • Classic white Polaroid frame, with your caption in the frame • Layouts from 1×3 strips to a 3×4 grid • Square (1:1) and portrait (4:5) export • Pinch to zoom, drag to reposition, tap to swap any photo • Adjustable grid lines and an optional caption • One tap to save the finished grid to Photos PRIVATE BY DESIGN Gridlai has no accounts and makes no network connections at all. Your photos are used only on your device to build the grid and save it back to your library. We collect nothing. Made by AIConcepts.Studio.

RevoCam is a video recording app that supports simultaneous recording with the front and rear cameras. You can capture yourself and the scene in front of you at the same time while recording, making it ideal for vlogs, product introductions, tutorials, travel videos, and more. Unlike ordinary apps that record with the front and rear cameras at the same time, RevoCam not only generates a composed video, but also saves the front camera video, rear camera video, audio, and subtitle file separately. This makes it easy to edit your footage again later. After recording, you can still freely adjust the border style, border color, width, and subtitle content of the small video window. You can also export the materials to your computer and continue editing them with professional video editing software. Features ・Record videos with the front and rear cameras simultaneously ・Swap the front and rear camera views ・Add a border to the small video window ・Customize the border color and border width ・Generate subtitles while recording ・Save foreground video, background video, audio, and SRT subtitles separately ・Readjust border styles and subtitles after recording ・Export a composed video, or export the original materials for professional editing Export Materials Separately On the video list page, select the video you want to export, then tap the share button in the lower-left corner. The following items can be exported as a set of materials: ・Foreground video ・Background video ・Audio file ・SRT subtitle file ・Composed video, if already generated This makes it convenient to continue post-production on your computer or in other video editing software. Video Composition and Export Tap a video on the video list page to enter the preview screen. On the preview screen, tap the share button in the lower-left corner. The app will first compose the video, then export the composed result. If the video has already been composed before, the app will automatically skip the composition step when exporting again and directly output the composed video. However, if you adjust the border style, border color, width, or other visual settings on the preview screen, the video must be composed again before the latest version can be exported. Use Cases If you are a vlog creator and want to record yourself while also capturing the product, scenery, or operation process you are introducing, this app is a great fit for you. Whether you are creating unboxing videos, product introductions, travel records, course explanations, or everyday sharing videos, simultaneous front and rear camera recording can make your content richer while giving you more flexibility for post-production. Try RevoCam and experience a more flexible way to shoot dual-camera videos.
