NEW Immigration bureau application; THIM

This is a new app immigrations rolled out and seems to be the TDAC and trip planner in one (along with other features that aren't active yet)

I was able to put in the data for a trip planned to come to thailand in Nov, and it said it would message me when it was time to file the health declaration and then give a QR code

I was also able to put in the data for a trip planned to come to thailand in 3 days and it let me fill out the health declaration form and gave a QR code on the spot.

It appears to be a fairly stable app although I had it close a couple times for no reason I could see 😲

The advantage is you can put in a future trip you have planned here and it will message you when it's time to do the health declaration and get the QR code

It's available on both Google Play and Apple Store

You can still file a TDAC via the online web-portal or at the airport when you arrive with the kiosks.. This THIM app is just piloting right now, BUT it appears functional and you should be able to use it when you enter thailand.

Here's the news article from The Nation about it

Answer summary
The THIM app is a new application rolled out by the Thailand Immigration Bureau that combines features of the TDAC (Travel Declaration and Approval Certificate) and a trip planner. Users have reported successfully entering trip data and receiving QR codes for health declarations when traveling to Thailand. The app is currently being piloted and is available for download on Google Play and the Apple Store. Users can still file TDAC online or at airports, and the app may evolve in functionality to include other immigration processes. Some users have experienced compatibility issues with certain phones, and there are questions regarding its use for different visa holders.
