Cronometer vs Lose It for Micronutrients in 2026: Test Results
Lose It is a competent calorie and macro tracker but is not designed around micronutrient depth. Cronometer's nutrient grid is the central feature of its product. For any user whose tracking goal includes nutrient sufficiency, this comparison is one-sided.

Quick Verdict
For micronutrient tracking, Cronometer wins this comparison decisively — and the gap is structural rather than incremental. Cronometer is built around the 84-nutrient grid as its central feature; Lose It is a calorie and macro tracker that surfaces a handful of micronutrients almost incidentally. If your tracking goal includes nutrient sufficiency for any reason — clinical condition, plant-based diet, athletic recovery, pregnancy, recovery from disordered eating — Cronometer is the structurally correct tool and Lose It is not.
What Cronometer Actually Does in 2026
Cronometer’s product architecture starts with the nutrient grid. The 2026 free tier ships with 84+ nutrients tracked by default, sourced primarily from USDA FoodData Central. The visualization is a daily grid that color-codes hits, misses, and excesses for every tracked nutrient.
Gold ($5.99/mo or $54.95/yr) adds biometric tracking, oracle nutrient targeting, fasting timers, and custom charts. The nutrient grid itself is on the free tier — Gold does not unlock additional nutrients.
For micronutrient tracking, Cronometer’s strengths are: the nutrient grid is the default UI rather than a hidden feature, every nutrient has daily-target context, and values trace back to USDA records you can verify if you want to.
What Lose It! Actually Does in 2026
Lose It is a calorie and macro tracker built around simplicity and habit-building. The 2026 product centers on the basic macro view: calories, protein, carbs, fat, plus secondary fields for fiber, sugar, and sodium. A few high-priority micronutrients (vitamin C, calcium, iron) appear in expanded views.
Premium ($9.99/mo or $39.99/yr) adds the Snap It photo logger, recipe import, advanced reports, and meal planning. Premium does not meaningfully expand the micronutrient view.
For users whose primary goal is calorie balance with simple macro context, Lose It is fine. For users who care about B12, EPA/DHA, choline, selenium, iron speciation, or any of the other clinically relevant micros, Lose It does not really compete.
Micronutrient Depth: Side-by-Side
We logged the same week of meals in both apps and recorded which nutrients were surfaced in the default view.
| Nutrient | Cronometer | Lose It |
|---|---|---|
| B12 | Yes (target context) | Limited |
| Folate (DFE) | Yes | No |
| EPA omega-3 | Yes (split) | No |
| DHA omega-3 | Yes (split) | No |
| ALA omega-3 | Yes (split) | No |
| Choline | Yes | No |
| Selenium | Yes | No |
| Iodine | Yes | No |
| Iron (heme/non-heme) | Yes (distinguished) | Total only |
| Zinc | Yes (phytate notes) | Total only |
| Vitamin K1/K2 | Yes (split) | No |
| Magnesium | Yes | Limited |
The pattern is one-sided. Anywhere a nutrient is clinically meaningful, Cronometer surfaces it and Lose It does not.
Accuracy Test: How They Compare on Weighed Meals
The DAI Six-App Validation Study (March 2026) measured Cronometer at ±5.2% MAPE and Lose It at ±12.4% on weighed reference meals. Cronometer’s tighter accuracy compounds in nutrient tracking because micronutrient values flow from the same database entries — when calorie values are right, nutrient values typically are too.
For nutrient-decision purposes, the accuracy advantage is meaningful. Lose It’s ±12.4% calorie MAPE translates to similar error bands on the nutrients it does track, which can swing whether a user reads as “hitting target” or “missing badly.”
Database Comparison: Size vs. Verification
Lose It’s database is roughly eight times larger than Cronometer’s by entry count. For micronutrient tracking, the additional breadth does not help — chain restaurant entries rarely include full nutrient profiles, and user-submitted entries often have missing nutrient values that read as zero.
Cronometer’s smaller, USDA-aligned catalog is the better tool for nutrient tracking specifically. The trade-off is fewer chain restaurant entries; the benefit is reliable nutrient values when entries do exist.
How Each App Handles a Plant-Based Week
We logged seven days of identical plant-based meals in both apps.
| Nutrient gap | Cronometer | Lose It |
|---|---|---|
| B12 (under 50% RDA) | Flagged on day 2 | Not surfaced |
| EPA + DHA (under 250 mg) | Flagged on day 1 | Not separately tracked |
| Choline (under AI) | Flagged on day 3 | Not tracked |
| Iodine (under RDA) | Flagged on day 4 | Not tracked |
| Selenium (under target) | Visible | Not tracked |
Cronometer surfaced five clinically relevant gaps; Lose It surfaced zero. For a plant-based user, that is the entire reason to track.
Pricing: Real Cost After 12 Months
| Plan | Cronometer | Lose It |
|---|---|---|
| Free tier | Yes (full nutrient grid) | Yes (basic macros) |
| Monthly Premium | $5.99 | $9.99 |
| Annual Premium | $54.95 | $39.99 |
Cronometer Gold is $15/yr more than Lose It Premium. For micronutrient-focused use, Cronometer’s free tier is already enough — Gold is optional. Lose It’s Premium does not meaningfully change the nutrient experience.
Where Lose It Still Wins
To be fair to Lose It because the comparison is one-sided on the micronutrient axis:
- Cleaner photo logging via Snap It (which Cronometer does not offer at all).
- Stronger restaurant chain database.
- Lower Premium price for users who want photo logging.
- Simpler interface for users who specifically do not want a 84-nutrient grid in their face.
- Better for users whose only tracking goal is calorie balance.
If your tracking goal does not include nutrient sufficiency, Lose It is genuinely a fine choice. The point of this article is not that Lose It is a bad app; it is that for the specific question “which is better for micronutrients,” the answer is decisively Cronometer.
Who Should Pick Cronometer
Pick Cronometer if you have any reason to track specific micronutrients, you are plant-based, you are pregnant or breastfeeding, you have ever had labs flag a deficiency, you are recovering from low-energy availability, or you simply want the deepest nutrient grid in the consumer market.
Who Should Pick Lose It
Pick Lose It if your tracking goal is calorie balance and basic macros only, you want photo logging via Snap It, you eat at chain restaurants frequently, you specifically prefer a simpler interface, or you do not care about nutrients beyond protein, fiber, and the headlines.
Bottom Line
For micronutrient tracking, Cronometer is the right answer. Lose It is a competent calorie and macro tracker but is not in the same category for nutrient depth. If micronutrients matter to your tracking goal, this comparison is one-sided. If they do not, both apps work — pick on simplicity, photo logging, or restaurant coverage instead.
Frequently Asked Questions
Is Lose It really that thin on micronutrients?
For default tracking, yes. Lose It surfaces the standard macros (calories, protein, carbs, fat, fiber, sugar, sodium) plus a handful of high-priority micros. It is not a nutrient-tracking tool.
Can Lose It track B12 or iron?
Some entries include B12 and iron values, but the experience is inconsistent. The default catalog does not consistently surface these nutrients with target context, which is the point of nutrient tracking.
Is the Cronometer free tier enough for serious nutrient tracking?
Yes. The 84-nutrient grid is on the free tier. Gold adds biometrics, oracle nutrient targeting, and similar power features but does not unlock additional nutrients.
Should I use Lose It if I do not care about micronutrients?
Sure. Lose It is a competent calorie and macro tracker for users whose primary goal is calorie balance. For users whose goal includes nutrient sufficiency, it is the wrong tool.
Does Cronometer's smaller database hurt micronutrient tracking?
No — the opposite. Cronometer's USDA-aligned catalog is more accurate per query, and accurate calorie data flows into accurate nutrient data. The smaller catalog is part of why the nutrient tracking is reliable.
Are there cheaper options with Cronometer-level nutrient depth?
Not really. Cronometer's free tier is already the most nutrient-depth-per-dollar option in the consumer market. The structural design choice of building around the nutrient grid is hard to replicate at lower cost.
