LOBSTR mobile app provides functionality for monitoring of Stellar assets rate changes. By turning on price alerts, you will not miss the jumps in the rate of your assets.
You can create Price Alert that notifies you when an asset's rate has reached a certain level.
Let's see how you can set one up.
For example, you need to be notified when the BTC price rises by 5%. To do this, you need to follow a few simple steps:
1) Choose Price Alerts in the sidebar of LOBSTR mobile app
2) Click on '+' and choose a BTC asset (BTC trustline should be added beforehand):
3) Set the asset price at 'Above +5%' value.
Done! You will be notified when the BTC price rises by 5%.
You can disable an irrelevant price alert using the corresponding switcher on the Price Alerts screen or just delete it from the list using the 'long tap' action on Android devices and or the 'swipe' action on iOS devices.
