They are charging me despite having previously paid for the full application. One thing that doesn't bother me is that it doesn't include the second digits, which I consider essential and easy to implement. It's a shame. ### 5/5 — Impressed by the design! *2026-01-28, version 1.0.6* How can I buy the in-app? Can't find it... => Found it: Hold cmd control while clicking in the mddle of the clock. RED, Great! ### 5/5 — Clock *2026-01-26, version 1.0.6* It is very different from all the other clocks I normally download, all must want to just sit and watch the dots just go round and around. You can make it beep on the hour and I think it talks as well. Wonderful looking clock when all lights are switch off in the dark. Love it. ### 4/5 — Why no update in over four years?!… *2025-12-29, version 1.0.6* I like it, but wonder why there hasn’t been an update in more than four years?? Has the developer passed away? 🤔 ### 5/5 — Impressed by the design! *2025-12-06, version 1.0.6* How can I buy the in-app? Can't find it... ### 1/5 — It’s purple … red requires extra payment *misleading* *2025-09-16, version 1.0.6* App Store shows it having a traditional red studio clock face. When the app runs, it’s locked to a lurid purple (Bubblegum) which is not why it was purchased. Bubblegum is suggested on app page as being an in-app extra, but it turns out red requires more money. Unimpressed with this false or misleading advertising. ### 5/5 — Simpatica *2025-09-13, version 1.0.6* Utile e carina 🌻 ### 5/5 — Something you never knew you needed until… *2025-07-28, version 1.0.6* Apart from being quirky, this is of course, to anyone in broadcast or production, a typical clock-face seen throughout the world in galleries and edit suites alike. Those ones are of course silly expensive and genlocked to the system, whereas this little gem is not only as reliable and probably better, but FREE ! No idea if possible, but…. Is there a way (for retail that is) that this could/can be ‘USB-sticked’ into a standalone old 3:4 LCD/LED monitor with usb port, and used like a studio wall clock timepiece without the computer/Tablet/Lappy connection/screen share ??? - I’d place an order straight away for six if possible ! just asking and anything to help monetise this awesome bit of kits existence too. ### 4/5 — One small request *2025-06-22, version 1.0.6* This is great app for Live broadcasts, and would be perfect if I could set a time offset and start it running myself. As I am sure many home producers do, I want to record a show 'as-live'. That is, in real-time but recorded in advance. If I could set the clock to a start-time, say 21:00:00, then wait until I press record to start it I would be able to give time-checks for a future time when the show goes out. To be absolutely ideal, there would also be a countdown to an end time displayed. Does such a thing exist? I would certainly pay for it. ## Frequently asked questions about Studio Clock GX2021 ### What does Studio Clock GX2021 do?
