Fix this app please

Ive been using this app for some time now but recently have had a ton of issues. The biggest issue being that the app shuts down continuously. Ive missed buses and overall I have already began to use the app less because of this. Please fix this issue before I stop using the app completely. Im just 1 user but this can quickly begin a trend
