Arvo + MacroFactor
Training AI + Nutrition AI. The complete fitness stack. Here's how they complement each other for maximum results.
Last updated: March 2026
How much does MacroFactor cost in 2026?
MacroFactor costs $11.99/month, $7.99/month on the 6-month plan, or $5.99/month on the yearly plan ($71.99/year) in 2026. Arvo costs €4/month (free during beta). They're complementary: MacroFactor tracks nutrition with adaptive algorithms, Arvo coaches your workouts with AI. Together they cover both training and nutrition.
MacroFactor, created by Greg Nuckols and the Stronger By Science team, has earned a reputation as the most intelligent nutrition tracking app available. Its adaptive algorithm learns your actual metabolic rate from weight trends rather than relying on generic formulas, then adjusts your calorie and macro targets weekly. For evidence-based nutrition coaching, MacroFactor sets the standard.
However, MacroFactor remains a nutrition-first app. It added a Workouts module in 2026 for logging training, but there's no AI program design, no weight suggestions, and no real-time coaching. That focus is deliberate: the Stronger By Science team built MacroFactor to do one thing exceptionally well—optimize your nutrition through intelligent algorithms and easy food logging.
This is where Arvo complements MacroFactor perfectly. While MacroFactor handles the nutrition side with adaptive calorie targets, Arvo handles training with AI that adapts every set based on your performance. Both apps share a philosophy of intelligent adaptation over static plans. Together, they cost approximately €10-16/month and cover both pillars of fitness progress: optimal training stimulus and optimal nutritional support. For serious lifters who want evidence-based approaches to both training and nutrition, this combination delivers comprehensive intelligent coaching.
Key insight: These apps aren't competitors - they're complementary. Arvo coaches your workouts. MacroFactor coaches your nutrition.

Frequently Asked Questions
Is MacroFactor a workout app?
Not primarily. MacroFactor is a nutrition and macro tracking app created by Greg Nuckols and the Stronger By Science team. It added a basic Workouts module in 2026, but its core remains calorie tracking and macro adjustments based on your weight trends. For AI workout coaching and programming, you need an app like Arvo.
Can I use Arvo and MacroFactor together?
Yes! They're complementary. MacroFactor handles your nutrition with adaptive algorithms. Arvo handles your training with AI coaching. Together they cover both sides of fitness: what you eat and how you train.
Which app should I get first?
Depends on your weak point. If your training is inconsistent or you don't know what to do in the gym, start with Arvo. If your diet is all over the place, start with MacroFactor. Ideally, use both for comprehensive fitness tracking.
Does MacroFactor have workout features?
Since 2026, MacroFactor offers a Workouts module for logging training (also sold as a Nutrition + Workouts bundle), plus expenditure tracking and Apple Watch activity integration. There's no AI workout programming, weight suggestions, or volume management though. Arvo fills this gap with complete workout management.
How much does MacroFactor cost?
MacroFactor costs $11.99/month, $47.99 per 6 months, or $71.99/year as of June 2026. There's no free tier, but new users get a free trial; a Nutrition + Workouts bundle is also available at $89.99/year. Arvo costs €4/month (free during beta) — together the two apps run roughly €10-16/month.
How much do both apps cost together?
MacroFactor: $5.99–$11.99/month depending on plan ($71.99/year for annual). Arvo: €4/month (free during beta). Combined: roughly €10–16/month for complete training + nutrition management. That's less than a single personal training session.
Is Arvo better than MacroFactor?
They're not competitors - they do different things. Arvo is an AI workout coach. MacroFactor is a nutrition tracker. Asking which is better is like asking whether sleep or exercise is more important. Both matter for results.
Does MacroFactor track MEV/MAV/MRV volume?
No. Even with its Workouts module, MacroFactor doesn't use scientific volume landmarks. Arvo automatically tracks MEV (Minimum Effective Volume), MAV (Maximum Adaptive Volume), and MRV (Maximum Recoverable Volume) per muscle group.
Can I sync Arvo and MacroFactor?
Currently there's no direct sync between the apps. However, both work independently and complement each other. Your nutrition data in MacroFactor and workout data in Arvo together give you complete fitness tracking.
Which methodology does MacroFactor use?
MacroFactor uses adaptive TDEE tracking based on your actual weight trends. It adjusts calories weekly based on how your body responds. For training methodologies (Kuba, Mentzer, FST-7, DC Training), use Arvo.
Is MacroFactor worth it if I use Arvo?
It can be. Arvo's Fuel module covers daily nutrition tracking (macros, AI photo logging, barcode scanning), while MacroFactor goes deeper with an adaptive calorie algorithm that recalculates your targets weekly from weight trends. If you want that level of dietary automation, the two still pair well.
Do both apps have offline mode?
Arvo has full offline functionality for workouts. MacroFactor has limited offline food logging. Both apps are designed to work well even with inconsistent connectivity.
Which app has better Apple Watch support?
Both apps support Apple Watch. MacroFactor integrates with Apple Watch for activity tracking. Arvo has a native Apple Watch app that logs sets from your wrist with live heart-rate tracking during workouts.
