MacroFactor is the serious lifter's macro tracker — built by the team behind Stronger By Science, with a weekly-adjusting algorithm and evidence-based coaching. AskBeforeYouEat shares that adaptive philosophy but wraps it in a calmer, free, and more accessible package. Both apps learn from your data; they just do it for different audiences.

MacroFactor's standout feature is its expenditure algorithm. Most trackers calculate your TDEE from a formula and leave it there. MacroFactor watches your actual calorie intake alongside your weight data and recalculates your true energy expenditure every week. After a few weeks of consistent logging, the app knows your real metabolic rate — not a formula's guess, but what your body is actually burning.
This is genuinely useful for people in deliberate body composition phases. If you're cutting for a competition or running a controlled bulk, MacroFactor adjusts your targets weekly based on how your body is actually responding. It's the kind of evidence-based approach you'd expect from the Stronger By Science team — the same people behind widely respected research reviews in the strength training community.
The goal-setting system is phase-based: set a target weight, pick a timeline, and MacroFactor builds a macro plan to get you there while adjusting weekly. For people who think about nutrition in terms of training phases — 12-week cuts, lean bulks, maintenance periods — the structured approach feels natural.
MacroFactor also recently launched MacroFactor Workouts, adding training logging alongside nutrition. The food database is curated for accuracy rather than size, which means fewer entries but more reliable data — especially for whole foods and common meals.
At $71.99/year ($0.20/day), it's priced as a coaching tool rather than a simple tracker. The positioning is clear: this is for people serious about body composition, not casual dieters.
The most immediate barrier: there's no free tier. None. You get a 7-day trial, and then it's $71.99/year or you lose access. For people who aren't sure about commitment-based macro tracking, that's a real hurdle. Most competitors — even premium ones — offer at least a limited free version.
The app is built for fitness enthusiasts, and the interface reflects that. If you don't think in terms of "bulking phases" or "expenditure adjustments," the experience can feel like it's not meant for you. The design is functional but data-dense — dashboards full of charts, expenditure graphs, and phase progress bars. It's powerful for its audience but intimidating for someone who just wants to eat better.
Food logging is traditional: search a database, select from results, enter quantities. No natural language parsing — you can't type "leftover pasta with meatballs and garlic bread" and have it understood. The curated database prioritizes accuracy but is smaller than competitors, so less common foods and ethnic cuisines sometimes require manual entry.
There's no conversational coaching. MacroFactor's algorithm adjusts your numbers, but it doesn't explain why or help you think through decisions. It won't answer "what should I eat for dinner to hit my protein target?" or "how should I think about this week where I traveled and ate out every night?" The coaching is implicit in the numbers, not explicit in conversation.
The weekly adjustment cadence, while smart, means the algorithm needs consistent data. If you skip logging for a few days, the expenditure calculation becomes less reliable. MacroFactor rewards discipline but doesn't handle inconsistency gracefully.
Both ABYE and MacroFactor believe in adaptive algorithms — the idea that your calorie target should change as your body changes. ABYE's Prime# algorithm does this continuously rather than on a weekly schedule, and it's included free. You get the same core insight — "my body burns X calories based on actual data, not a formula" — without paying $72/year for it.
ABYE lets you describe meals in plain English: "two eggs, avocado toast, and a coffee with oat milk." The AI parses it instantly. You can also take a photo of your plate. MacroFactor's database-search approach is accurate but slower — especially for mixed meals where you'd need to log each component separately.
ABYE's built-in AI coach turns data into conversation. Ask it what to eat, whether you're on track, or how to think about a day that went sideways. MacroFactor adjusts your numbers silently — it's coaching through math, not through guidance. For people who want to understand their nutrition rather than just be told what targets to hit, that conversational layer matters.
MacroFactor is explicitly built for people who already think about nutrition in terms of phases, macros, and body composition. ABYE is built for anyone who wants to eat better — whether that means losing weight, building muscle, or just understanding what's on their plate. The calm, no-judgment interface doesn't assume you already speak the language of fitness nutrition.
MacroFactor is the right tool if you're serious about body composition — competitive lifters, bodybuilders, or anyone running a deliberate cut or bulk with specific timeline goals. If you want the most evidence-based expenditure tracking available and you're willing to log consistently to feed the algorithm, MacroFactor's weekly adjustments are best-in-class. The integrated workout logging makes it a natural choice if you want nutrition and training in one place.
ABYE is the better fit if you want:
MacroFactor and ABYE agree on the important thing: static calorie targets are outdated. Both use adaptive algorithms that learn from your actual data. The difference is audience and access. MacroFactor is the precision coaching tool for serious lifters — powerful, data-dense, and worth $72/year if you're running structured phases. ABYE is the intelligent companion for everyone else — adaptive, conversational, and free. Same philosophy, different execution.
Adaptive algorithm, AI coaching, full macro tracking — all free, forever. No trial period.
