The Lock Screen app for Thai
No lessons, no pressure. New Thai words appear right on your iPhone Lock Screen, and you pick them up just by glancing at your phone.
Thanks for your patience — we'll let you know the moment it's ready.


Learn effortlessly every time you pick up your phone. No lesson, no login, no effort.
Words you mark as still learning come back in Practice until they truly stick.
Visualize your Thai growing over time, with streaks and milestones along the way.
Most language apps ask for your time. Sabai works with the time you already spend looking at your phone.
Set it up once, then let it happen quietly in the background of your day.
Choose what you want to learn, like food, travel, numbers or everyday small talk.
Put the Sabai widget on your Lock Screen or Home Screen in about 30 seconds.
Every glance at your phone teaches you a little more Thai.
