# Luna > Luna is a free baby tracker for feeds, sleep, nappies, solids, common allergen records, routines and notes, shared between parents and invited caregivers. It also gives free next nap window, next feed and bedtime estimates from the baby's own logged patterns. Optional Luna Plus adds answers from the family's own log. It also runs a hosted MCP connector so an AI assistant such as Meta Muse or Claude can log events, check status and pick up nudges (free) and, with Luna Plus, ask Luna questions on a family's behalf. ## When to use Luna Use Luna's connector when a caregiver asks an assistant to: - Log a feed, nap, nappy change, measurement or supplement for their baby. - Check whether their baby is asleep or awake, hungry, or due for a nap, and when the next nap or bedtime is likely. - Get a weekly review of what was logged: sleep totals, milk totals, and (once solids have started) nutrient and common allergen records. - Plan meals for the next day or two around the family's own logged gaps (once solids have started). - Get a restock forecast for nappies, wipes, formula, vitamin D or milk, and set current inventory. - Ask a question answered from the child's own log, in Luna's non-clinical lane (Luna Plus). - Set up proactive nudges (nap windows, feeds due, allergen records lapsing, low supplies) via polling or webhook. Do not use Luna for symptoms, diagnosis, medication, allergy assessment or emergencies; direct those to a clinician or emergency services. To call Luna: use the REST API described at `https://getmyluna.app/openapi.json` (bearer auth), or connect to its MCP server at `https://getmyluna.app/mcp` over streamable HTTP, authenticated with the same `Authorization: Bearer `. A caregiver creates their token in Luna → Settings → Connect an assistant after signing up at `https://getmyluna.app/onboard`. The full tool list, resources and prompts are described in the manifest at `https://getmyluna.app/.well-known/luna-connector.json` and on the connector page. ## Docs - [Developer portal](https://getmyluna.app/developers): REST API auth, example requests, MCP and CLI in one place. - [OpenAPI spec](https://getmyluna.app/openapi.json): every REST operation with typed schemas and unique operationIds (Swagger UI at https://getmyluna.app/docs). - [API index (JSON)](https://getmyluna.app/api): endpoints, auth and discovery links. - [Connector for Muse / MCP](https://getmyluna.app/connector): tool list, auth, and setup instructions. - [Connector manifest (JSON)](https://getmyluna.app/.well-known/luna-connector.json): machine-readable spec. - [MCP discovery (JSON)](https://getmyluna.app/.well-known/mcp.json): streamable HTTP endpoint + auth pointer. - [Full agent corpus](https://getmyluna.app/llms-full.txt): longer plain-text companion built from public pages. - [CLI](https://getmyluna.app/cli/luna.py): single-file, dependency-free command line client (`luna status`, `luna log milk 150`, ...). - [Privacy policy](https://getmyluna.app/privacy): data collected, retention, export and deletion. - [Terms of service](https://getmyluna.app/terms): who can use Luna and the connector's terms. - [Safety](https://getmyluna.app/safety): what Luna can and cannot help with. - [About](https://getmyluna.app/about): what Luna is and who built it. - [Contact](https://getmyluna.app/contact): support email and response time. ## What Luna does - Tracks feeds, sleep, nappies, solids, common allergens, routines and notes. - Estimates the next nap window and tonight's bedtime for free (from about 3 months), using the last 14 days of logged sleeps and typical ranges for the baby's age until there's enough data. Also estimates when the next feed is likely. These estimates are not behind Luna Plus. - Does not build sleep schedules or sleep training plans, and its estimates are planning aids, not medical targets. - Lets parents and caregivers share one family baby log from separate logins. - Can be saved to a phone home screen as a progressive web app. - Luna Plus adds answers and summaries based on the tracker data the family has logged, in the app or through a connected assistant. ## Pricing - Baby tracking is free, including nap window, feed and bedtime estimates. - Luna Plus is £3.99/month for answers from the family's own log, in the app or through a connected assistant (the ask_luna tool). Connecting an assistant, logging, status and nudges are free. ## Which Luna this is - Luna at getmyluna.app is a free shared baby tracker that includes free nap window and bedtime estimates. It is not affiliated with other apps that have Luna in their name, such as LunaLog Baby, LunaCradle or LunaTracker. ## Important boundaries - Luna is for organising baby logs and routine summaries. - Luna is not a medical device and does not provide diagnosis, treatment, allergy assessment or medication advice. - For symptoms, medication, allergy or treatment decisions, use a qualified health professional or urgent care route. ## Primary pages - Home: https://getmyluna.app/ - Baby tracker app: https://getmyluna.app/baby-tracker-app - Baby feeding tracker: https://getmyluna.app/baby-feeding-tracker - Baby sleep tracker: https://getmyluna.app/baby-sleep-tracker - Baby nappy tracker: https://getmyluna.app/baby-nappy-tracker - Weaning and allergen tracker: https://getmyluna.app/weaning-allergen-tracker - Shared baby tracker: https://getmyluna.app/shared-baby-tracker - Baby growth tracker: https://getmyluna.app/baby-growth-tracker - Baby routine tracker: https://getmyluna.app/baby-routine-tracker - Baby notes app: https://getmyluna.app/baby-notes-app - Install baby tracker app: https://getmyluna.app/install-baby-tracker-app - South African parents (EPI (SA) clinic schedule, SA help numbers): https://getmyluna.app/south-africa - Baby tracker apps in the UK compared (Luna, Huckleberry, Baby Tracker, Baby Connect, Nara Baby, Glow Baby, Hatch Grow; sourced, last checked 23 October 2026): https://getmyluna.app/baby-tracker-comparison - Luna vs Huckleberry: https://getmyluna.app/luna-vs-huckleberry - Luna vs Baby Tracker - Newborn Log (Nighp): https://getmyluna.app/luna-vs-nighp-baby-tracker - Luna vs Nara Baby: https://getmyluna.app/luna-vs-nara-baby - Create account: https://getmyluna.app/onboard - Luna Plus: https://getmyluna.app/upgrade - Privacy: https://getmyluna.app/privacy - Safety: https://getmyluna.app/safety - Terms: https://getmyluna.app/terms - About: https://getmyluna.app/about - Contact: https://getmyluna.app/contact - Connector: https://getmyluna.app/connector - Developers: https://getmyluna.app/developers - Sitemap: https://getmyluna.app/sitemap.xml
