Great training, glitchy apps

Ive used several apps from this developer including the c25k bridge to 10k and this is the third time Ive been through the 1/2 marathon training. Ive been disappointed by the apps consistently. Hals coaching and the progression are great, but the app is one of the worst apps of any kind that Ive used. It quits unexpectedly, and doesnt provide any warning, meaning that your progress that day is lost. Very unreliable to keep any training data. Cannot recommend anyone use it or any of the others in this series.
