We’ve started playing tennis again now that we have some friends living in the building who are keen. The court we play at needs to be booked in person, and the people manning the office are not very good at English.
This prompted me to make a custom lock screen wallpaper for my iPhone which has the Bahasa Malaysia translations for common things: days of the week, numbers up to 20, left & right (good for taxis).
I used it today when booking the court for next week. Handy. Paid itself off in language frustration already!
