When you feel your energy is running low, start a boost. You can start a boost any time by clicking the bolt icon in your menu bar and clicking Start Boost...
When Ampll detects your energy is running low, it sends you a notification. You can choose a boost directly from the notification using the Options drop down.
Once you've logged a boost, your teammates may choose to recognize you by giving you bolt emoji rewards. You can also recognize your teammates with bolts for logging their own boosts. (See Recognizing your teammates).
