TrakMac vs Cronometer
Cronometer is the macro tracker for people who want every micronutrient measured and don't mind doing the data entry to get it. TrakMac is the macro tracker for people whose logging would have died by week three using anything that requires a search bar. Both are good. They're built for different problems.
Side by side
| Feature | TrakMac | Cronometer |
|---|---|---|
| Logging method | Voice — describe what you ate | Search a database, enter grams |
| Food database | Restaurant cache + USDA + AI estimation | Verified Cronometer database (very accurate) |
| Micronutrient tracking | Calories + protein + carbs + fat | Calories + macros + 60+ micronutrients |
| Time to log a meal | ~15 seconds (speak it) | 60–120 seconds (search, find, weigh) |
| Target setting | Calculated from your fitness signals (bench, mile time, training pattern) | Height/weight/age formula (Mifflin-St Jeor) or manual |
| Kitchen scale required | No — estimates within ±20% | Strongly recommended for accuracy |
| GLP-1 / appetite-aware targets | Yes — calorie floor + protein bias auto-applied | No — same formula regardless of medication |
| Platform | iOS (Android not planned) | iOS, Android, Web |
| Price | $7.99/mo or $59.99/yr (after 7-day trial) | Free tier; Gold $9.99/mo for full data |
When Cronometer is the right call
- You care about micronutrients (iron, B12, magnesium, vitamin D, etc.) — Cronometer's database is the best in the consumer space for this and it's not close.
- You weigh your food and you like weighing your food. The precision payoff is real.
- You're on a medical protocol (chronic disease management, kidney issues, etc.) where exact tracking matters more than speed.
- You need cross-platform (iOS + Android + Web) — TrakMac is iOS-only by design.
- You're fine with friction. Logging takes longer with Cronometer; the data quality is the trade.
When TrakMac is the right call
- You've tried logging apps before and quit by week three. The single biggest predictor of macro tracking success is whether you actually log — TrakMac's voice-first design exists to remove the search step that kills consistency.
- You train, and you want targets that respect what you actually do — not the BMI formula every other app inherits.
- You're on a GLP-1 (Ozempic, Mounjaro, Wegovy, Zepbound). TrakMac adjusts the calorie floor and protein bias automatically; Cronometer treats you like everyone else.
- You eat real plated food, not packaged food. Voice logging beats database search the second you're looking at a Chipotle bowl that doesn't have a barcode.
- You want close-enough estimates and to move on with your life. ±20% of perfect, applied every day, beats perfect tracking you abandon.
The honest call
If you're a registered dietitian or someone whose body composition depends on micronutrient precision, use Cronometer. If you're a fitness enthusiast who wants to actually keep tracking past month two and have targets that fit how you train, use TrakMac. There's no shame in picking the one that survives your real life — the best tracker is the one you still open in week ten.
FAQ
- Is TrakMac more accurate than Cronometer?
- No — Cronometer has the more accurate food database, full stop. TrakMac is intentionally an estimator that lands within ±20% of the real number. The trade-off: TrakMac logs 4–8× faster, which means most users actually keep using it. Consistency beats precision for body composition outcomes outside of competitive bodybuilding.
- Can I track micronutrients in TrakMac?
- No. TrakMac tracks calories, protein, carbs, and fat. If micronutrient tracking matters to you, Cronometer is the better tool. We may add directional micronutrient signals later, but precision micros are a different product.
- Why is TrakMac iOS-only?
- Voice-first logging requires deep speech recognition integration and we wanted to ship one platform exceptionally well rather than two platforms compromised. iOS first; Android is not on the roadmap.
- Does Cronometer support GLP-1 users?
- Cronometer doesn't differentiate. Same calorie target formula whether you're on Ozempic or not. TrakMac coerces GLP-1 users to a Maintain calorie target and pushes protein bias higher to protect lean mass during appetite suppression.
