doublesDoubles vs MacroFactor.
Pick MacroFactor if you want precise data: a verified food database, detailed micronutrients and an algorithm that re-estimates your expenditure every week. Pick Doubles if you'd rather say or snap food than search and weigh it, and want a partner to talk to that remembers your days.

Where MacroFactor is the better pick
- Its weekly algorithm re-estimates your expenditure from what you log and how your weight trends, then adjusts your targets for you. It's well known and well liked for this.
- Its food database is verified, and it shows detailed micronutrients.
- It runs on Android as well as iPhone, and has a companion workouts app.
- Its monthly plan is a dollar cheaper, and it offers a 6-month plan.
Where Doubles is the better pick
- Logging by voice and photo is the main way in, not a beta feature. Say "two eggs and toast" and it's logged.
- A partner you can ask "what fits tonight?" or "what should I order here?", who remembers your plan and your recent days.
- Two numbers to hit, calories and protein, instead of a full macro split.
- A Recomp plan and trip days with no targets, set by telling your partner.
- About the same yearly price: $69.99 against $71.99.
Who shouldn't use Doubles
- You're on Android or want to log on the web. Doubles is iPhone only for now.
- You want a free tracker. After the 7-day trial, Doubles is paid.
- You want to weigh and log every gram, or track lots of micronutrients. Doubles covers calories and protein first, plus carbs, fat and fiber.
- You want workout programming. Doubles reads your workouts but doesn't plan them.
- You're pregnant, have a medical condition or have a history of disordered eating. Talk to a professional first; a calorie tracker may not be right for you.
