Stopped working — hangs at startup

This app was five star but recently it has stopped working. It hangs on the splash screen at startup and has to be force-quit.

This happens on phones of other family members (XS Pro Max) also so it’s not specific to my phone (11 Pro Max).

EDIT: uninstalling and reinstalling fixed it. Updated review to five stars.

Best Thai Dictionary

This s far and away the best dictionary for Thai. It works offline, gives great example sentences, and has a transcription search feature to help find words you can say but aren't sure how to spell. If anyone reading this also studies Mandarin, this is the Pleco of Thai dictionaries. No ads and a flea dedication to the language. I would pay for add one if the developer creates them.

Used for over a year now

I have the other Paiboon app, and this app has more translations and extremely helpful example sentences. I have been using this app for over a year now and was the critical factor for my fluency in Thai. Freaking hard work was put into this bad boy right here and it's more helpful that any other app for Thai, hands down.
