I found a lack of flexibility with training plans where you had to pick between 1 and 3 days per week for running, nothing more. It would be nice to be able to select say 4 or 5 days a week. I found with the training plans, some runs say you should say jog for a time period then do runs/sprints for certain distances then walk. If I have my phone in an inaccessible place where I can’t see the screen, it’s important to get audio feedback on what I’m up to and what I need to do next. How do I know when to switch from jog to run if I don’t get an audio message to do so? The only audio cues you can select are distance based milestones which aren’t useful when the training plan is telling you to run for certain times. If you hold your phone in your hand or can look at the screen for the sprint/walk segments, this app works well. If you don’t have access to the phone screen during your run, I find it unusable.
