AI nutrition coach Ask about your log. Approve what changes.
Coach reads the logs and plans you saved, answers your questions, and drafts meal, workout, body-metric, supplement, plan or goal changes. Nothing is written until you approve it.
For people who want to ask questions about their own food and training logs and get changes back as drafts, without a chatbot that writes to their log on its own.
Free to download. Optional Pro subscription. iPhone only.

In the app
- Questions about your own logs
- Drafts you approve
- Photo or body report attached
- Reviews on request
- Pro feature
An AI coach is only useful if it works from your real data and never gets ahead of you. GemFit's Coach, available on Pro, answers questions about your own saved logs and plans, and every change it proposes comes back as a draft you can edit, approve or discard.
That approval step is the whole design. Coach can suggest a lunch, rewrite a plan day or propose a new protein target, and none of it touches your log until you say so.
What Coach does
Ask Coach a question and it answers from what you have logged: meals, workouts, body metrics, supplements and the plans you are following. Ask it for a change, for example a dinner that fits the calories you have left or a lighter version of tomorrow's session, and it returns an editable draft.
You can attach a meal photo or a body report to a request, so a question about a plate or a trend has the data in front of it. Drafts cover meals, workouts, body metrics, supplements, plans and goals, and each one waits for your approval.
- Questions answered from your own saved logs and plans
- Meal, workout, body-metric, supplement, plan and goal changes as drafts
- Meal photo or body report attached to a request
- Day or week reviews only when you ask
Drafts carry their own labels
A meal Coach drafts for you is an AI estimate, the same as a photo estimate. Review the foods and portions before you approve it. Once saved, the entry carries its source and confidence label like every other entry in the log, so a Coach-drafted meal never looks like a barcode match to an official source.
The same goes for workouts and goals. A drafted session is a suggestion until you check the sets and weights. A drafted goal is a number to consider, not a target that changes on its own.
Reviews when you ask for them
GemFit does not send you a weekly recap or a grade. If you want a look at a day or a week, ask Coach for one and it reads the logs from that period and tells you what it sees. It works from the entries you saved.
Ask in plain language: how did protein look this week, which days did I train, what would make tomorrow easier. If the answer includes a change, it comes back as a draft you decide on.
- Day or week reviews on request, not on a schedule
- Answers grounded in saved logs and plans
- Changes proposed as drafts, never applied silently
Where Coach stops
Coach is not a medical tool. It does not diagnose, treat or replace a clinician or a registered dietitian, and it does not promise a weight outcome on any timeline. Questions about a medical condition, a medication or an eating disorder belong with a professional.
It also cannot act without you. Coach cannot save an entry, change a target or edit a plan on its own. Every proposal is a draft, and the draft is yours to approve or discard.
Common questions
Will Coach tell me what to eat?
If you ask, it will draft a meal or a plan that fits your logs and targets. The draft is editable and is not saved until you approve it.
Do I need Coach to use GemFit?
No. Coach is a Pro feature you open when you want it. Manual food and workout logging, barcode lookup, meal-photo analysis and progress reports are free and work without it.
Is Coach a medical or clinical tool?
No. It is a fitness and nutrition assistant that works from your own logs. It does not diagnose, treat, prescribe or replace a qualified professional.
Does Coach send me a weekly summary automatically?
No. Day or week reviews happen only when you ask for one. There are no scheduled recaps or scores.
Can Coach change my log without asking?
No. Every meal, workout, body-metric, supplement, plan or goal change arrives as a draft. Nothing is saved until you approve it.
Log one real day, then decide.
Food, training and body measurements in one private log. Coach and drafts are there when you want them, and nothing is saved until you approve it.
