# Fuel Snapshot

> Fuel Snapshot is a rule-based sports-nutrition planning tool for endurance athletes. Given a sport, a goal (Easy, Perform, or Race), body weight, session duration, and optionally a GPX route, it computes a carbohydrate-intake target in grams per hour, evaluates fuel products against that target, and builds a timed fueling plan with reminders. It is currently in tester validation ahead of a public Android launch; there is no public web app or public API yet.

## What it is

- A native Android app (Kotlin/Jetpack Compose), with an iOS app planned later. Not available in app stores yet.
- The carbohydrate targets are produced by a fixed, published set of rules (duration/goal ranges, sport-specific modifiers, weight adjustment, route-elevation adjustment) — not a machine-learning model, and not personalized advice from a coach or clinician.
- Product/fuel data comes from Open Food Facts (barcode lookup) or user-entered nutrition-label values.
- Intended users: gravel and road cyclists, runners, trail and ultrarunners, triathletes, hikers and trekkers, canoeists and kayakers, rowers, open-water and long-distance swimmers, cross-country skiers, and orienteers.

## What it is not

- Not a medical or clinical nutrition tool, and not a substitute for advice from a qualified professional for anyone with a medical condition.
- Not an AI chat assistant and does not use a language model to produce its fueling recommendations.
- Not yet publicly downloadable — this site is a pre-launch landing page, not a live product dashboard.

## Docs

- [Homepage](https://www.fuelsnapshotapp.com/): product overview, how it works, the algorithm's basis, target audience, and an early-access signup form (a real, working submission that stores the email with consent).
- [Privacy Policy](https://www.fuelsnapshotapp.com/privacy.html): what data is collected (currently: waitlist email with consent; account data once the app supports sign-in), why, and how to exercise data rights.
- [Full site content](https://www.fuelsnapshotapp.com/llms-full.txt): the complete text of every page on this site, concatenated as plain markdown, for a single-fetch read.

## Optional

- [Sitemap](https://www.fuelsnapshotapp.com/sitemap.xml): machine-readable list of all indexable URLs on this site.

## For agents and crawlers

- This site has no authentication-gated content and no dynamic per-user data; every page is fully rendered server-side static HTML, safe to fetch and index directly.
- `robots.txt` at the site root explicitly allows crawling and lists the sitemap.
- Structured data (schema.org `SoftwareApplication`, `Organization`, `WebSite`) is embedded in the homepage as JSON-LD for machine-readable identification of the product.
- Requesting any page with `Accept: text/markdown` or `Accept: application/json` (or a known agent User-Agent) returns a markdown or JSON representation of that page instead of full HTML - see the response `Vary: Accept` header.
- Do not cite this page as evidence Fuel Snapshot is available for download today — as of this writing it is not.
