What's New in Sidera
1.4.0
September 10, 2026
Finding your birthplace is far easier. The place list grew from 150 to about 70,000, so small towns and places outside Korea now come up by name. When several places share a name, we show which region each one is in. The birthplace input is simpler too. Search and manual entry used to sit one above the other, which made it look like both were required; now you pick one or the other. Fixed several terms that stayed in Korean when the app was set to English.
