Best Calorie Counter App for Bodybuilding and Bulking
If you are bulking or cutting and you have outgrown MyFitnessPal's unreliable database, three apps are worth paying for in 2026: MacroFactor (£72/yr, adaptive algorithm), Cronometer Gold (£48/yr, verified database + micronutrient depth), and MyFitnessPal Premium (£64/yr — yes, you still need the barcode scanner back).
What logging this seriously looks like
The typical user who logs 5+ days per week for 12 weeks loses 4–8 lb. Heavier starting weights see more; smaller deficits see less. If you log ad-hoc 2–3 days per week, expect roughly no change — the difference between "tracking" and "tracking enough" is the whole game.
Real annual cost in 2026: Truly-free track-only = £0 (Lose It free, Cronometer free, FatSecret). Solid mid-tier = £24–£60/year (Cronometer Gold £48, Yazio Pro £35, MacroFactor £72). Coaching-included = £150–£300/year (Noom 6-month £159, WW Core £276/year).
Skip the rest for serious goals. Realistic expectation: if you log every meal for 16 weeks, MacroFactor's adaptive TDEE will land you within ±150 kcal/day of the right target — that is the difference between a clean +0.5 lb/week bulk and a sloppy "I think I gained some fat?" outcome. If you log 4 days a week, none of these apps fix the math problem; you fix it.
MacroFactor — the adaptive algorithm pick
MacroFactor's core advantage is weekly TDEE recalibration from actual weight trend vs logged intake. Static apps (including MFP and Cronometer) use a formula estimate that may be 200–300 kcal/day off for your individual metabolism. After 4–6 weeks of consistent logging, MacroFactor knows your actual maintenance.
For a 16-week bulk at +0.5 lb/week: if your maintenance is 2,200 kcal but the formula estimated 2,400, and you eat 2,700 kcal (300 above estimated maintenance), you are actually eating 500 kcal above real maintenance. You will gain faster than intended and likely add more fat than planned. MacroFactor detects this in weeks 3–4 and adjusts your target.
The £72/year price is real. No free tier. Non-negotiable if you want the algorithm. Full MacroFactor review →
Cronometer Gold — the micronutrient pick
For athletes with high training volume, micronutrient tracking matters for recovery — zinc, magnesium, B6, iron, vitamin D. Cronometer tracks all of them at a level no other consumer app matches.
The USDA-verified database means macro splits on chicken, rice, and eggs are accurate. Where Cronometer falls behind MacroFactor: no adaptive TDEE. Your calorie target is static unless you manually update it.
The right call: use MacroFactor for targets and add Cronometer free for a weekly micronutrient audit, or use Cronometer Gold as your single app if budget is the constraint. Full Cronometer review →
MyFitnessPal Premium — the legacy pick
MFP has the largest database for restaurant and packaged food. For lifters who eat out frequently and need chain-restaurant macros, MFP's coverage is still the best. The tradeoff: 18% error rate on user-submitted entries, no adaptive TDEE, £64/year for the barcode scanner that should be free.
If your diet is primarily whole-food meal prep with occasional chain-restaurant meals, MFP is the correct pick only if you are already invested in the ecosystem. Otherwise, start with MacroFactor or Cronometer. MacroFactor vs Cronometer head-to-head →
