doublesDoubles vs Cal AI.
Short answer
Both log meals from a photo. Pick Cal AI if you want photo logging on Android, or one of its lower-priced offers. Pick Doubles if you want one clear price, a longer trial, a protein minimum that keeps your muscle, and a partner you can ask questions that remembers your days.

Where Cal AI is the better pick
- It runs on Android as well as iPhone.
- Some of its offers may cost less than Doubles. Its App Store page lists plans from $2.99 to $29.99.
- It's photo-first and quick to start, if all you want is to snap a meal and see the numbers.
Where Doubles is the better pick
- One price, shown before the trial with the date of your first charge: $69.99 a year or $12.99 a month.
- A 7-day free trial instead of 3 days.
- Protein is a minimum you hit, set at 1.6 g per kg, or 2.0 g per kg if you lift or pick Recomp, not just one macro among four.
- Besides photos, you can say what you ate, type it, scan a label or tap a saved usual.
- A partner remembers your plan and your days, answers questions, and you can correct any number by saying what's wrong.
- Plans for Recomp, Maintain and trips, not only weight loss.
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.
