IronFuel

Most lifters run a workout app and a food app that never talk to each other. Train legs hard and the calorie app still shows the rest-day target. IronFuel logs sets in about three taps or by voice, reads a meal from a photo, and moves that day's calorie and protein target the moment a session ends — then tells you how much protein you still have to eat. Workout logging, full history and barcode scanning are free and unlimited. iPhone today, Android next.
