Application crashes all the time, timing are not coherent

Ive got an iPhone 6+ and the application is crashing all the time, nearly unusable!!! Please fix this as soon as possible as deinstall and reinstall is not working. :-(
Also the proposed timings are underestimated by 20%-30% (at least on bus)... Do an effort to get a better app! :-(
