The Best Macro Tracker for Bulking and Gaining Muscle
Mainstream apps are built for weight loss, not building muscle. Here is how to track your macros and progressive overload for a successful bulk.
⚡ TL;DR Key Takeaways
- Bulking App Bias: Mainstream fitness trackers focus heavily on calorie deficits and weight loss, offering poor systems for muscular weight gain.
- Natural Strength Progression: Building mass requires tracking progressive overload alongside a consistent caloric surplus (typically 300–500 kcal above maintenance).
- Tailored Bulking UI: Nulls Tracker consolidates detailed lifting set logs and rapid macro tracking in one simple dashboard designed for muscle growth.
I struggle with bulking. Eating enough clean food to gain mass is already a full-time job, and most macro trackers are simply not tailored to bulkers. Almost every app on the market is built for weight loss, and the workout logging sections, if any, are not designed for splits, weights, sets, and reps, which are essential for tracking progressive overload under a targeted daily calorie surplus of 300 to 500 calories (as recommended in sports nutrition guidelines by the International Society of Sports Nutrition).
Why use a macro tracker designed specifically for bulking?
I designed the Nulls Tracker interface specifically for someone in my shoes. My goal is to make logging entirely frictionless using smart autofills based on your history alongside text- and photo-based macro estimation.
The workout logging interface is also designed to be fast and satisfying. Your standard splits as presets carry over, your exercises are tracked internally to speed up logging, and you can track and visualize progressive overload on all your exercises and best records.
In the video above, Nulls tells me exactly what I need based on my real data.
By tracking just the crucial data for a bulk in a streamlined app that adds next to no extra work to your routines, you will be perfectly set up for a personalized Nulls analysis. In the example above, Nulls told me exactly what I needed based on my data. No useless "wellness" or "balance" language. Just the raw numbers to optimize my bulk.
Value Proposition
Compared to corporate apps with expensive monthly subscriptions, Nulls Tracker offers complete manual macro and workout logging free forever, with zero ads. If you want shortcuts and automated insights, the Pro subscription starts at just $2.50 a month (billed annually at $30/yr, Reg. $8.00/mo) or $5 a month on the monthly plan (Reg. $8.00/mo). There is a free 7-day Pro trial with no credit card required, and you always fall back to the free manual logging tier afterward. You only pay to cover AI computing costs, never for bloat features that don't matter to your bulk.
