Social fitness app Private first. Sharing is a choice.
Your log is private by default. Eligible adults can turn on sharing, post what they choose, and message other members directly. Teens get private tracking without social features.
For adults who want the option to share what they log with other people, and for everyone who wants a tracker that stays private unless they decide otherwise.
Free to download. Optional Pro subscription. iPhone only.

Sharing works best when it is a choice rather than the price of keeping a log. You can use every tracking feature in GemFit without ever turning on sharing, and nothing you log is visible to anyone else unless you post it.
For adults who want the company, the Feed tab is where shared workouts, meals and progress live, and direct messages handle the conversations that follow. Access depends on age and region, and the app checks both before social features are available.
What the Feed is for
The Feed is narrow on purpose. It is for the things people in GemFit actually log: a session, a meal, a progress summary. There is no separate social identity to maintain, because a post starts from something already in your log.
Sharing is optional and available only to eligible adults. Once it is on, you choose what to post, and direct messages let you follow up with someone one to one.
- Optional sharing for eligible adults
- Posts built from workouts, meals and progress you logged
- Direct messages between members
Shared entries stay estimates
A shared meal is still the estimate it was in your log. Sharing does not verify the numbers, and a source or confidence label explains where an estimate came from without turning it into proof. The same is true of a shared workout: the sets and weights are what you entered.
Review what a post includes before you share it, and share only the numbers you are comfortable with that audience seeing. Progress summaries can be exported and shared from the Progress tab on the same terms.
Private by default, gated by age and region
Every new account starts private. Sharing is gated by age and by region, and GemFit checks both before social features appear. Accounts for ages 13 to 17 get private tracking only, with no feed, no posting and no direct messages.
Adults who never want a social layer can leave sharing off and use GemFit exactly as a private tracker. Body metrics, progress photos and journal entries are private tracking data and are never shared unless you deliberately post them.
- Private by default for every account
- Age and region checks before sharing is available
- Teen accounts limited to private tracking
Coaches, clients and affiliate codes
Coaches can build workout, meal or mixed plans and assign them to clients who accept an invite. The client then sees the plan day by day and can log meals and workouts directly from it. The client's log stays the client's; what they share back is up to them.
The coach affiliate program gives each coach a personal code to share. Conversations between a coach and a client can happen in direct messages, and a client can export a progress summary to send along when they want a second set of eyes.
Common questions
Is GemFit a social media app?
No. It is a food and training tracker with an optional sharing layer for eligible adults. Everything is private unless you post it.
Can I keep all of my data private?
Yes. Leave sharing off and GemFit works as a private tracker. Body metrics, progress photos and journal entries stay private unless you deliberately share them.
Who can use the social features?
Eligible adults only. Sharing is gated by age and region, and accounts for ages 13 to 17 get private tracking without a feed, posting or direct messages.
Can a coach see my logs?
Accepting a plan invite does not hand over your log. What a coach sees is what you choose to share: an exported progress summary, a post, or a direct message.
What is the coach affiliate program?
Coaches in the program get a personal code they can share with the people they bring to GemFit.
