Let me start by saying this app is a great integration for Fitbit and Apple Watch users in a household. My family is obsessed with the challenges and the message board where we write pleasant insults to motivate one another is a definite thumbs up.
My con for this app is well it doesnt record my steps accurately. It only logs on the app, steps Ive taken with my iPhone physically on my person. Today for example Im at 3,000 steps but Argus says Im at 1,500. Worsening the blow, my sisters with fit-bits are killing it on the competition. Im not a sore loser most of the time but every step counts and I need Apple Watch HealthKit or who knows what is involved, to be more accurate.
