Flawed

Could be better with the generation of time-of-day code. Seems to get the time at program start, before it starts the generator so it’s always late compared to device (real) time. The paid version does not indicate this would work properly. Until the generated code is closer (exactly) to actual time-of-day then cannot recommend.

Didn’t work with my iPhone

The app installed easily, allows selection of frame rate and warns that the free version will only run up to midnight however the it only runs for a second and then stops.

Shame really, it seemed ideal for my purposes - to set clocks.

Should’ve read the reviews.

If you are looking to generate a file that you can insert into an edit with this app, you will not be able to do so.

Latest update 3.0 does NOT work at all.

May2023 version 3.0 starts for a moment then immediately stops. 👎👎

Not fixed

Shirt burst big is not fixed. Outside of that it would be useful. But doesn’t generate contunuous code, only .5 second burst as of today 3/31/2022
