While participating in the ISS SSTV activity, I wanted to check the predicted transit time. However, the predictions were inaccurate. I suspect this is because the orbital information hasn't been updated, and the app doesn't have a manual update option.
Coordinates OM10ws, check the transit time of rs38s.
The ISS detector detected an event at 22:20:28, with an angle of 59 degrees.
The "ham" personal tool was detected at a time of 22:26:30, with an angle of 63 degrees.
The prediction provided by the app created by the original poster should be incorrect compared to the online predictions from AMSAT.
