Sweatmeal vs MacroFactor
Sweatmeal and MacroFactor both adjust your calorie target from your real weight trend. MacroFactor is a strong general macro coach with a large verified food database and weekly updates; Sweatmeal is built for people who train, flexing each day’s target with training load, wearable data and a race calendar. Choose by whether your training should move your daily numbers.
Facts about MacroFactor below come from its public website and help centre, as of October 2026. Features and prices change; check their site for the current version.
What do they have in common?
Both estimate your energy expenditure from what you eat and how your weight moves, instead of trusting a formula forever. MacroFactor’s help centre describes its expenditure as “Calories in - Change in stored energy = Calories out”, updated as new intake and weight data arrive. Sweatmeal starts from a validated resting-metabolism equation and refines your burn from your weight trend over time.
Both are honest that a starting estimate is an estimate. That shared foundation is why this comparison is about what each builds on top of it.
How do they compare feature by feature?
| MacroFactor | Sweatmeal | |
|---|---|---|
| Adaptive expenditure | Yes, from logged intake and weight trend, with weekly target updates | Yes, from weight trend, alongside wearable burn |
| Daily target and training | Optional “calorie shifting” to days you choose, within a weekly budget; optional step-informed updates | Each day’s target moves with that day’s training load and recovery |
| Exercise calories | Not used directly; its docs explain it “doesn’t need data about energy expenditure during exercise” | Uses measured burn from a connected wearable |
| Wearables | Apple Health and Health Connect; direct Fitbit support removed | Whoop, Oura, Strava, Ultrahuman, Apple Health, Health Connect |
| Race planning | Not a listed feature | Race calendar; carb floor rises to 8 g/kg before endurance races of 90 min or more |
| Food logging | Barcode, label scanner, AI photo, voice, search of 1.36M verified foods, recipe import | A line of text or a photo (Pro) |
| Coaching | Algorithmic weekly adjustments | AI coach that names your next meal (Pro) |
| Training app | Separate MacroFactor Workouts app | None; reads training from wearables and calendar |
| Platforms | iOS, Android | iPhone (Android coming soon) |
| Price | $11.99/month, $47.99/6 months or $71.99/year, 7-day trial, no free tier | Targets, wearables, trends, calendar free; logging and coach in Pro |
Where is MacroFactor stronger?
MacroFactor is stronger on food logging and on long-term calorie precision for body-composition goals. A verified database of 1.36 million foods, a nutrition label scanner and recipe import make logging fast and accurate.
Its weekly budget is deliberate: as its help docs put it, raising one day lowers others so the week stays on target. For someone whose main goal is losing fat or gaining muscle at a set rate, that design is hard to beat. It also has a companion strength-training app.
Where is Sweatmeal stronger?
Sweatmeal is stronger when training is the main variable in your week. Its target reads the day you actually had: a long ride, a rest day or a race. Training days keep a carbohydrate floor, an approach sports scientists call fuelling for the work required (Impey et al., 2018).
Three things follow from that:
- Wearables connect directly. Whoop, Oura, Strava and Ultrahuman feed burn and recovery into the target; low recovery eases a deficit.
- Races are planned. Put a marathon in the calendar and the two days before carry a carb-load floor; see our marathon carb-load.
- Protein follows lean tissue. It is set per kilo of fat-adjusted weight, not raw bodyweight.
What is the honest trade-off?
The approaches differ in philosophy. MacroFactor’s position is that changes in activity show up on the scale, which its algorithm then measures, so it does not need workout data. Sweatmeal argues that for athletes, the day matters too: fuelling a hard session on a rest-day budget hurts training, even if the weekly average is right.
Neither is wrong; they optimise for different users. Sweatmeal does not connect to Garmin directly, and its logging and coach need Pro.
Who should use which?
Choose MacroFactor if:
- your main goal is body composition at a steady rate;
- you want the fastest, most accurate food logging and a large verified database;
- your training is consistent week to week, so a weekly budget fits.
Choose Sweatmeal if:
- you train for endurance events, Hyrox or hybrid goals;
- you wear a Whoop, Oura or similar and want its data to move your target;
- you want race-week carb-loading planned for you, and a coach that tells you what to eat next.
