Does the THIM app replace the TDAC for entry into Thailand?

I don't know if I can ask this here, but does anyone know if the "THIM" app is in effect and replaces "TDAC"? 🤔
Answer summary
The THIM app does not replace the TDAC but offers an alternative way to submit it. Users can fill out their TDAC information in the app, which then stores personal data to streamline future submissions. The app is currently operational but still has limitations and may not be fully reliable. Travel and health declarations are required for entry into Thailand, and while some users find the app useful, others express skepticism about its effectiveness.

The THIM app looks better, if you have several trips already planned, you can fill all your TDAC requests in advance and only submit your health condition 72h before your trip.

I'm travelling next Wednesday, and I just completed my trip details on the new THIM app. I can't enter the health declaration part until tomorrow afternoon. I won't do the normal TDAC entry on the website this time and will see how it goes. I'll report back here if there are any problems.

It's basically a waste of time and no doubt won't work properly.

I also don't understand why anybody would get excited enough to post anything about it.

The whole Thai immigration and visa system is a pathetic joke. Changing all the time,WAY too complicated and confusing 🤮💩🤬.Simplify it ffs!Why tf do we have to report every 90 days when we have been granted permission to live here ,for a start? Just more pointless,needless,red tape bureaucratic bullshit 🙄🥱

Yes, it's working. The only thing you can use it for at the moment, is to submit your TDAC. Using the app to do it should give you an advantage the next time you enter Thailand, by remembering your data from the last entry.

It will be on line in September 2026. I can't guarantee that it will not crash many times before the Thais get it right. Let's see. They gave up playing with the TM30 for all on line after weeks of software problems.

No, the app does not "replace" the TDAC. It's just another method you can use to submit the TDAC, if you want. Or you can use the website. You still need a TDAC to enter Thailand.
