CPR Beat 0.4.1

Fixed

• The rescuer-switch countdown digits and the option chips (rate, countdown, click sound,
  language) shrink to fit their frames instead of being clipped. On 360 dp wide screens such as
  the Samsung Galaxy S25 the countdown showed "02:0" and the Settings chips "1 мин … 5 мин" ran
  over their outlines; a larger system font had the same effect. (#22, #23)
• Settings: the countdown chips read Off / 1 / 2 / 3 / 5 and the unit moved into the section
  label ("Default countdown · min"), the way the rate section already did.

CPR Beat 0.4.0

Changed

• The rescuer-switch countdown now looks like a button: it has an outline and a ⟳ icon, and
  "tap to change" is shown under it while the metronome is stopped. Tapping it still cycles the
  interval Off, 1, 2, 3, 5 minutes.
• 30:2: the first breath tone now sounds at 30 % of the breath pause and the second at 65 %,
  instead of right after compression 30 and at half the pause, so a lone rescuer has time to
  move to the head and open the airway. The breath pause is 7 s by default and adjustable
  3–9 s (was 5 s, 3–8 s).

CPR Beat 0.3.1

Fixed

• STOP returns the rate, mode and rescuer-switch countdown chosen on the main screen to the
  values from Settings, as the in-app help and the README describe; the choices used to stay
  until the app was closed. Reported by an F-Droid tester.

CPR Beat 0.3.0

Added

• Russian interface.
• Settings → Language: Auto (the phone language), English or Русский. On Android 13 and later
  the same choice also appears in the system's per-app language settings.

Changed

• APKs and app bundles no longer carry Google's dependency-info block, an encrypted blob that
  F-Droid and IzzyOnDroid reject.

Fixed

• Status bar and navigation bar icons stay light on phones that use a light system theme; they
  used to be dark and nearly invisible on the app's dark background.
