It always take more than 4 attempts to connect the app to the camera (the official App is guaranteed to fail just once, this app will randomly fail 2 to 4 times) Even worse, when transferring photos, the progress would always stick at 100% and the photos will not show up in my library. Honestly I don't know how the developer had the audacity to basically force it's users to buy in to the subscription up front without any (or minimal) trial periods. Stay away from this app. ### 1/5 — No GR IV support, Chinese required *2025-10-31* GR IV not listed in device list, doesn’t seem to be able to connect. Also if you can’t read Chinese you won’t be able to read parts of the app interface. ### 1/5 — It's in chinese *2025-10-15* Most of the application is in Chinese I did not know that before purchasing because you have to purchase before you can try it. I’ve written to the developer, but we’ll see. ### 5/5 — 好棒好棒好美好美 *2025-05-29* 希望可以未来同步配方到GR 3x！我不知道做不做得出来但如果能做出来就太神了 ### 1/5 — Impossible to use *2025-05-12* Got as far as transferring images from a GRIII into the app, which in itself is counterintuitive and tricky. Then none of the sliders seems to change the image in any way once in the app. Also doesn’t allow for import of RAW images from desktop or anywhere other than from your iPhoto app. This app should show your photo nice and large and then let you fine tune all the variables with responsive sliders. I’m honestly at a loss at how anyone can create a custom look with this ### 5/5 — 非常好用 *2025-04-26* 比官方 App 的 UI 设计好太多，价格不贵，跟相机联动的功能真是赏心悦目。 美中不足的是不像官方 App，用 Wi-Fi 连接没法同步 GPS 信息，只能用蓝牙同步。 ### 4/5 — 相册管理功能 *2025-04-18* 希望新增一个远程连接相册管理功能 ### 5/5 — Automatically sync by the day. *2025-04-13* as topics ### 1/5 — 垃圾产品 *2025-04-08* 就是骗钱的 ### 5/5 — good *2025-02-17* very good **Developer response:** thanks❤️ ## Frequently asked questions about GR Lab ### What cameras does GR Lab support?
