心慌时，先跟着做 90 秒稳下来。Lento 是自我调节工具，不替代医疗、治疗或紧急救助。

What Lento does

One immediate path, not another thing to manage.

Lento keeps the first screen simple: one action to begin. The first protocol is deterministic, lasts 90 seconds, and avoids breath-hold instructions.

Start fast

No account wall for the acute flow. The steadying screen is available immediately.

No-hold breathing

Follow one exhale, a longer exhale, a grounding cue, and a simple wave-passing step.

Use what helped

Afterward, mark Better, Same, or Worse. Lento uses that record to keep the next step small.

Prepare before the next wave

Set up reliability without crowding the first screen.

Prepare options stay outside the acute moment: Action Button shortcut setup, device haptic rhythm, trusted contact status, and a night default.
