What's New in Kyanite Pro
1.2.2
September 11, 2026
Announcements Home can now show a short note from us when something new ships, like a new calculator or a fix you asked for. Tap it to read the whole thing, or dismiss it and it is gone for good on that phone. No ads, no offers, no links out, and it works whether or not you have an account. Fixed Tanks, products and sheets shared with a crew would not delete. Deleting one now clears it off every phone on the crew the way it always should have. Adding a tank or a tank group while a crew is selected also saves it to that crew instead of quietly filing it under your own records. Everything else is unchanged: the calculators, charts and sheets still run with no signal and no login.
