Just auto and manual screenshot stitching, literally all you need from an app like this. (It has some extra editing features I don’t care about, but they’re there as a bonus) ### 5/5 — Sumix on iOS 26 *2026-04-16, version 23.02.01* Easy to use.. Does everything I want without features that get in the way.. ### 5/5 — Functional, No Gimmicks, and easy to use! *2025-10-24, version 23.02.01* I rarely write reviews, but this app is top notch and needs to be further up in the store. It works perfectly, making stitching multiple screenshots and saving as jpg or pdf an easy task. Plus, unlike the 3 other apps I tried first, it doesn’t make you pay to save the stitched image. Thanks to the dev for offering this app for free! ### 5/5 — Functional, Easy, and works! *2025-09-15* I rarely write reviews, but this app is top notch and needs to be further up in the store. It works perfectly, making stitching and saving as jpg or pdf an easy task. Plus, unlike the 3 other apps I tried first, it doesn’t make you pay to save the stitched image. Thanks to the dev for offering this app for free! ### 5/5 — No ads, works exactly as advertised *2025-09-07, version 23.02.01* Thank you to the wonderful developer who made an app to do a basic yet powerful function to stitch photos together without shoving ads down our throat. 20 stars! ### 4/5 — Nice *2025-04-19, version 23.02.01* Stitching pictures of various sizes is causing an error, so I contacted the developer who promised a fix. Despite this issue, the automatic stitching feature works perfectly. This app is definitely a keeper, and I highly recommend it! ### 1/5 — « Can’t stitch. Images must be of the same size » *2025-03-30, version 23.02.01* J’ai essayé plusieurs fois, et ça ne marche pas. Je ne sais pas exactement de quelle taille sont mes images mais elles sont quasiment identiques et avec les autres applications ça marche, alors pourquoi pas ici ? ### 5/5 — App rất hay *2025-03-13, version 23.02.01* Cảm ơn ad nhiều. App hay lắm ### 5/5 — Only one that works well *2025-02-23, version 23.02.01* I tried 3 others that either refused to stitch, didn't stitch properly, or required payment. This was the only one that worked, does it fast (automatically attempts with last few screenshots on app open), and offers to delete the original screenshots afterwards. These are the sort of apps that truly help people be more efficient. Curious, what stitching algorithm do you use? I'd like to have this as a UWP/Windows Phone app too! ### 5/5 — The best! *2024-12-01, version 23.02.01* So far, the best screen capture app I’ve ever used. ## Frequently asked questions about Sumix ### What does Sumix do?
