Was great before the update. Now is functional but irritating touse.buttons are mysteriously smaller and the dark mode version is clearly not made by anyone who actually used dark mode as it is pure black and white. Would like a settings option to turn it back to the old larger keyboard and more greytone. Sound is not an issue as i have all system sounds turned off by default. On the plus side the ability to reuse a previous calculation has returned which makes my life a lot easier
