Fitness App Help
(www.loseit.com)
I've been using MacroFactor since January and it's been the best app for me since my main struggle is simply choosing what my calorie intake should be. It doesn't track workouts (by design) but if you consistently log your weight and food, its algorithm tells you how much you should be eating based on your weight loss goal rate, and constantly adjusts as it gets more data.
I use FitNotes (Android only). I really like because of how simple it is. Keeps track of your rep maxes, volume, estimated 1RM, etc.
