Boilr is a free, as in freedom, Android app which monitors Bitcoin, cryptocurrencies, cryptoassets, futures and options, and triggers price alarms according to your settings.

Boilr supports 90+ exchanges and all their pairs.

Market data is retrieved directly from the exchanges via Wi-Fi or Mobile Data (if allowed), using libdynticker.

Price Hit

Triggered when price crosses the alarm's upper or lower limit. One limit may be left empty to create an alarm with a single trigger.

Price Change

Triggered when price changes more than X amount (in currency or percentage) in a specified time frame (e.g. 15 min). It uses a rolling time frame: price is fetched with a given update interval (e.g. 30 s) and compared with the price fetched one time frame ago (e.g. 15 min ago).

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.

Lists of exchanges, pairs and alarms are fully searchable, allowing quick alarm setup and configuration.

Sound and vibration are configurable globally and individually for each alarm.

Delete alarms with a swipe.

Reorder alarms after a long click.

Supports multiple languages: Chinese, Czech, French, German, Italian, Japanese, Polish, Portuguese, Russian and Spanish.

There is an alternative light theme.
