What is the longest real exposure time on an iPhone X with manual camera apps?

On an older iPhone 6, a manual camera app allowed up to 1/2-second exposures. On an iPhone X, what is the maximum shutter time you can get with manual apps such as Halide or ProCam? I'm specifically wondering about the longest true hardware-supported exposure, and whether longer settings in some apps are real exposures or simulated slow-shutter effects.

It is dependent on the Third party app you are using and not the phone itself.
I have several apps that allow me to use shutter speeds from fractions of a second up to 60 seconds and even bulb ( as long as you want ). I have used these apps on my iPhone 6 and my new iPhone 8+.
I use Procam 5 as my main app but i have others. It has a slow shutter mode. ( i am not affiliated with procam, just a user )
Do some research when you are choosing an app to see if you can find out what the manual control options for each app.
EDIT: I asked the pro cam five support staff the question and here is there reply
"Hi , Thanks for getting in touch with us. The longest exposure time supported by the iPhone X hardware is 1/4 sec. Longer exposure time are digitally simulated. Please don’t hesitate to contact us again with additional questions or feedback. Best",

It depends partly on the app, but the iPhone X hardware appears to limit true single-frame exposure to about 1/4 to 1/3 second. One user reports Halide on iPhone X allows settings from 1/3" down to very fast speeds, while ProCam support said the longest exposure supported by the iPhone X hardware is 1/4 second.
Anything longer than that in some apps is typically a simulated slow-shutter mode rather than one continuous sensor exposure. These modes usually blend or stack multiple frames to mimic a longer exposure.
So, for an iPhone X, expect the longest real manual exposure to be roughly 1/4–1/3 second, with longer advertised times depending on app-based processing rather than the sensor doing a true long exposure.
