Supports 2 alarm types: * Price Hit - Triggered when price crosses the alarm's upper or lower limit. * Price Change - Triggered when price changes more than X amount (in currency or percentage) in a specified time frame (e.g. 15 min).

Sound and vibration are configurable globally, and individually for each alarm. Lists of exchanges, pairs and alarms are fully searchable, allowing quick setup and configuration. The alarm list behaves as your ticker, where you can reorder your alarms and directly change their limits. Triggered alarms ring, displaying their status, until you turn them off. Just like an alarm clock. Alarms can also be set to snooze automatically on price retrace. Market data is retrieved directly from the exchanges via Wi-Fi or Mobile Data (if allowed). Boilr supports all available on libdynticker, as all their pairs. For a version history check the GitHub releases page.
