A macro tracker has two halves: the targets and the entries. GemFit keeps the targets in your hands. You set calories, protein, carbs and fat yourself, along with steps, water and sleep if you want them, and the Home tab shows today's totals against those numbers.
The entries are where the AI helps. A photo, a barcode, a text description on Pro, or a USDA search gives you a draft with calories and macros filled in. You check it, change what needs changing, and save. The label on the entry tells you whether the numbers came from an official source or from an estimate.
Targets first, then the log
Start by setting the calorie and macro targets you want to hold. GemFit does not pick them for you. If you are working with a coach or a clinician, enter the numbers they gave you. On Pro, you can ask Coach for a goal change and it will come back as a draft you can accept or discard.
From there, each meal is logged in the Log tab. Serving presets make repeat portions quick to enter, and manual entry is always available when you know the numbers from a label. Whichever route you take, the entry is shown to you before it is saved.
- Calorie, protein, carb and fat targets you set
- Steps, water and sleep targets alongside them
- Serving presets and manual entry on every tier
- Goal changes drafted by Coach on Pro, approved by you
AI drafts, you approve
Photo logging uses image analysis to suggest foods, portions, calories and macros. Text logging on Pro turns a meal description into an editable entry. Barcode lookups depend on available product data from Open Food Facts, with USDA data or official restaurant nutrition for supported lookups; confirm the product and serving against its label.
Photos cannot reliably reveal every ingredient or portion. Review the suggested foods, serving size, and confidence label before saving. AI output is still an estimate rather than a verified measurement, so adjust the portion when you know better.

- Text-to-entry drafts on Pro
- Barcode lookup with the product and serving shown for confirmation
- Pro micronutrient enrichment adds vitamins, minerals, allergen and diet flags
Source and confidence on every entry
A calorie number with no origin is easy to over-trust. GemFit labels each entry as official source, web-verified, AI estimate, or unresolved, so a barcoded yogurt and a photo of a stir fry never look like the same quality of data.
The labels stay on the entries after saving. When you look back over a day, you can see which meals rest on published nutrition and which rest on an estimate, and decide for yourself how much weight to give the total.
Macros and a deficit, without promises
GemFit does not promise a rate of weight loss, and it does not grade your day. It shows the targets you set, the entries you saved, and in the Progress tab the average intake and weight summary for 1, 3, 7 or 30 days, a custom date, or all time, with daily calorie bars and a weight sparkline.
If you want a second opinion on the numbers, Coach on Pro can answer questions about your own saved logs and, when you ask, review a day or a week. It works from the entries you saved, and nothing it suggests is written to your log until you approve it.
Common questions
Can I lose weight using GemFit's macro tracker?
GemFit does not promise a specific weight loss outcome. It helps you keep an honest log against targets you set and shows average intake and weight over the period you choose. The results depend on what you do with that information.
How accurate is photo-based logging?
Photo estimates are labeled as AI estimates and are meant to be checked. They cannot see hidden ingredients or exact portions, so review the foods and serving size before saving. Barcode matches to an official source are the most reliable entries.
Do I have to weigh my food?
No. You can use serving presets, barcodes, photos, a USDA search or manual entry. Weighing gives you a better number to type in, but it is never required.
How does GemFit calculate my calorie target?
It does not set one for you. You enter the calorie and macro targets you want to hold. On Pro, you can ask Coach to propose a change, and the proposal arrives as a draft you approve or discard.
Does the tracker show vitamins and minerals?
On Pro, micronutrient enrichment adds vitamins, minerals, and allergen and diet flags to a food entry. The free tier tracks calories, protein, carbs and fat.
