Most apps are using a-is that allow 4-10 updates per minute. This one appears to do 1. Sometimes. If you put it in the background, it looses the current price. No custom sounds. Alerts are insignificant single ding , no real options, graph is off, and no way to view anything but their version of 3 chart options, max of 2 weeks history. App should have been free. Maybe with an ad bar, but it’s not ready to be a revenue stream app. Then make a pro version with features . Currently, it seriously stinks.
