Comparison
Kexo vs MacroFactor
MacroFactor is the reference app for adaptive expenditure, and its system is more mature. Kexo uses the same energy-balance idea in a simpler weekly update, then adds chat logging and coaching across the rest of your week.
Last reviewed September 3, 2026. Author: Jozef Toth. This is not a paid comparison, and MacroFactor did not review it.
What both apps do
Both apps use the same basic math. They combine the calories you log with the change in your weight trend to estimate how much energy you use. Neither needs a wearable. Your next target follows what you actually logged and how your weight moved, not how closely you followed last week’s plan.
MacroFactor explains this process in its help article Understand the expenditure calculation. Kexo explains how far the weekly target may move on Adaptive expenditure.
Where they differ
| Mechanism | MacroFactor | Kexo |
|---|---|---|
| Update cadence | Ongoing expenditure from intake and trend weight, updated as you log | Once a week, on a 21-day window |
| Energy from weight change | Accounts for fat vs lean tissue energy density at different rates of loss or gain | Uses a flat 7,700 kcal per kg. It is simpler, but one fixed conversion cannot reflect every type of weight change |
| How far the target may move | Their published help does not list Kexo-style weekly step caps | +150 / −100 kcal per week; total +25% / −15% of the starting estimate |
| Thin or messy logs | Designed to handle missed weigh-ins; MacroFactor describes partial-day logging as the Achilles heel | Waits when there is too little data or the result looks implausible; after four such weeks, it slowly returns toward the starting estimate |
| Logging | Food log and database first. Fast if you like searching and barcodes | Chat first: text, photo, voice, or barcode. Searching a food database is not the main way you log |
| Coaching beyond the number | Nutrition program and expenditure-driven targets | AI weekly review of food, sleep, training, gut, and how you feel. The coach narrates the calorie math; it does not invent it |
| Languages / company | English-first, long-running US product | English and Slovak. Sparkclrt s.r.o., Banská Bystrica |
Where MacroFactor is better
- A more mature way to learn your calorie needs. Years of public documentation, better handling of fat versus muscle, and resilience we have not matched.
- A food log people already trust if they want to search, scan, and weigh.
- Documentation. Its help center lets us describe the product without guessing.
- Scale and time in market. If you want the best-documented adaptive tracker and you like database logging, start there.
When Kexo is the better fit
- You will not keep logging in a food database for six months, but you will text or photograph dinner.
- You want the weekly target to follow your logged intake and weight trend, with a coach that also looks at weekends, sleep, and protein.
- You want clear limits on how far the weekly target can move and when Kexo will wait.
- You need Slovak.
What we are not claiming
- We do not claim Kexo’s expenditure estimate is more accurate than MacroFactor’s. We have not run that comparison.
- We do not claim a measured accuracy figure for either product.
- We do not claim MacroFactor is “just a database.” Adaptive expenditure is central to its product.
