And the image effect is quite good. It looks really great! Looking forward to your more and better products. ### 5/5 — Works great for me *2025-03-21, version 2.4.5* I would recommend this product and app. It’s easy to use and lets you transfer things in four color. The app is easy and any issues are called user error. I give it a thumbs up! ### 5/5 — Good app *2025-01-08, version 2.4.5* I believe the authentication issues have been resolved and they make pretty good updates to the app. It can be slightly glitchy but for the most part works pretty good! ### 4/5 — Please add Widgets & Shortcut function *2024-11-21, version 2.4.0* Imagine every time you switch on your phone, the eink display changes, which give you a new look, every time you unlock your phone! Or, maybe a button that we can add to our Lock Screen, click it and the eink will refresh to a new background without opening the app. ### 1/5 — App no longer works *2024-06-09, version 2.2.1* Newest updat doesn’t let you do anything. Says illegal device when uploading photo. ### 1/5 — Newest Update Broken *2024-06-06, version 2.2.1* "Illegal devices" now shows up when trying to send to the back. Don't upgrade ### 5/5 — So far very good *2024-05-03, version 2.1.2* Love the case and app has been very good without any issues. ### 5/5 — Great quality case with a special extra *2024-03-30, version 2.1.0* To start with this is a very good phone case and has a robust stand along with proper clean action buttons However the eink display is great fun. You have to bear in mind the colour limitations when selecting images but the results are excellent. I’ve had no problems using the app and changing images loads of times without any issues. The only problem is choosing something that stays for more than a few hours😃 Would recommend highly. ### 3/5 — cool concept, needs refining *2024-03-09, version 2.0.2* not sure if this will be updated anytime soon, but the app is a bit buggy. the saved case projects remove the arrangement upon reopening, which is quite frustrating. otherwise quite decent and i enjoy using this case ## Frequently asked questions about Reink ### What does the Reink app do?
