Which is better, Coachly or MacroFactor?

It depends on what you want. MacroFactor is the stronger pure macro-tracking app, with a more refined nutrition algorithm and a larger food database. Coachly is the stronger integrated app — workouts, macros, AI coach, and adaptive programming in one place, with calorie targets that shift based on your actual training. MacroFactor users wanting workout tracking now need a second app (MacroFactor Workouts, launched 2026); Coachly does both natively.

What does MacroFactor do better than Coachly?

MacroFactor's nutrition-only focus shows. Their food database is larger and more polished (Stronger By Science has years of head start). The macro algorithm has been tuned over multiple iterations. Their brand authority on macro science is real — they spawned from a respected sports-science publication. If you want the deepest nutrition tracking and don't need workout programming in the same app, MacroFactor is excellent.

What does Coachly do better than MacroFactor?

Integration. Coachly is one app for training, nutrition, sleep, and an AI coach that reads all of it. Your calorie target shifts when training volume shifts; the programme deloads when sleep tanks. Coachly also includes adaptive strength and hypertrophy programming as a first-class feature, has a body recomposition goal MacroFactor lacks, and runs at £99.99/year vs roughly £144/year for the MacroFactor + Workouts combination.

Is Coachly cheaper than MacroFactor?

Coachly alone (£99.99/yr) is slightly cheaper than MacroFactor's nutrition app alone (~£72/yr) is a fair-ish comparison if you ONLY want macro tracking — but Coachly's £99 includes workouts and an AI coach that MacroFactor doesn't have. The full comparison is Coachly £99.99/yr vs MacroFactor + MacroFactor Workouts combined at roughly £144/yr.

Can I use both Coachly and MacroFactor?

Technically yes — both apps read from Apple Health, so your weight and Apple Watch workout data flows to both. But the whole point of Coachly is that one app reading both sides delivers integration the two-app stack can't. Running both apps reintroduces the manual macro-vs-training reconciliation the integration was designed to solve.

MacroFactor is built by Stronger By Science Technologies LLC, a US company that grew out of the Stronger By Science research and podcast platform. Coachly is built by Coachly App Ltd, a UK indie company registered in Scotland (SC887439) — no VC, no growth-hacker advisors. Different scale, different operating philosophies.

Which one is right for you?

A few honest filters.

You only want to track macros. You already have a workout app you love. MacroFactor's nutrition-only depth is genuinely best-in-class. If you're set on Hevy/Strong/Fitbod for training and just want the cleanest macro tracker, MacroFactor is the right pick. MacroFactor

You want one app for both training and nutrition, with calorie targets that actually reflect what you did in the gym. This is the core wedge. A two-app stack — even MacroFactor + MacroFactor Workouts — doesn't share state, so the macro side can't react to training. Coachly was built integrated from day one. Coachly

You're running a body recomposition. MacroFactor users flag in App Store reviews that the app lacks a dedicated body-recomp goal. Coachly treats recomp as a first-class goal with both training and macro algorithms tuned for it. Coachly

You want an AI coach that reads your training, food, and sleep together. MacroFactor doesn't have one. Coachly's AI coach reads your weekly training, macro adherence, and HRV/sleep before answering questions or running weekly check-ins. Coachly

You value brand authority and want the app with the longest research-backed pedigree. MacroFactor's lineage from Stronger By Science gives it more depth in the nutrition-science conversation. Coachly is newer; the evidence-based approach is the same but the brand recognition isn't. MacroFactor

You care about EU hosting, privacy, and an indie founder vs a venture-backed US company. Coachly is UK-indie, EU-hosted, never sells data. MacroFactor is a US company; their data practices are standard for a US SaaS but not particularly privacy-forward. Coachly

You're on Android. MacroFactor is cross-platform. Coachly is iOS only (Android port is in development as of mid-2026; not yet released). MacroFactor (for now)

You want to try both before committing. Both apps offer free trials. Coachly is 14 days; MacroFactor is 7 days. Run them in parallel for a week and see which app's workflow you'd actually use daily. Try both

What about MacroFactor Workouts?

The new app from the same team — and what it changes (and doesn't) about the comparison.

In early 2026, the MacroFactor team launched MacroFactor Workouts — a separate iOS app for workout tracking and adaptive strength/hypertrophy programming. It addresses MacroFactor's biggest gap, but as a distinct app rather than a feature merge.

The trade-offs that creates:

Two apps, two subscriptions. The combined cost (~£144/yr) is higher than Coachly's single £99.99/yr.
Two icons, two logins, two notification streams. Friction.
No shared state. This is the bigger problem. MacroFactor's macro algorithm doesn't read your MacroFactor Workouts training data — so calorie targets don't adjust to actual training volume. The integration that makes calorie cycling work doesn't exist between the two apps.
No AI coach. Neither app has one. The "coach" in MacroFactor is an algorithmic macro adjuster, not a conversational LLM with full context across training + nutrition.

For Coachly's intended user — a serious lifter who wants training and nutrition to actually inform each other — the MacroFactor Workouts launch confirms the integrated-app thesis rather than undermining it. The team there is solving the same problem; they just made a different architecture bet.

Honest questions, honest answers

Is MacroFactor's macro algorithm better than Coachly's? For pure nutrition-only adaptation, MacroFactor's algorithm has more iteration behind it — they've been at it longer with a nutrition-only focus. Coachly's algorithm adapts using training data as an additional input MacroFactor doesn't have. So "better" depends on what you're measuring: depth of nutrition tuning (MacroFactor) vs cross-system integration (Coachly).

Does Coachly's food database have everything MacroFactor's does? Not quite. MacroFactor's database is larger and more polished. Coachly uses Open Food Facts + Edamam (2M+ foods including UK and US chains), which covers the practical needs of most lifters but isn't as deep on edge cases. If your daily logging hinges on obscure restaurant items, MacroFactor still wins on database.

Is the AI coach actually useful or is it generic? The AI coach reads your actual training, macro adherence, sleep, and weight trend. It refuses medical advice by design and signposts to a doctor for anything clinical. It's not a generic LLM with no context — it has your actual data when answering. Whether that's useful is subjective; the App Store reviews suggest most users find it accountable.

What if I just want MacroFactor's nutrition + a separate Hevy? Valid setup, and a lot of lifters run it that way. The trade-off is the same: two apps, no shared state, calorie target doesn't move with training. Cheaper if you use free-tier Hevy (~£72/yr total just for MacroFactor); more expensive if you pay for Hevy Pro AND MacroFactor.

Will Coachly merge into MacroFactor's space or vice versa? The architectures are different bets. Coachly is staying single-app integrated. MacroFactor has committed to the two-app split. Both seem confident in their direction. Neither is converging on the other's approach.

Can I switch between them later? Yes. Both apps let you export data (Apple Health for body metrics, CSV for food log). Migration friction is real but not blocking. The bigger commitment is the workflow muscle memory — switching apps every 6 months is unproductive regardless of which one's "better."
