Quickstart
Get the app, sign in with your phone number, log your first entries, and connect skcal to your tools.
1. Get the app
Install skcal on iPhone or Android, or open app.skcal.fit in a browser. All three use the same account.
2. Sign in
Enter your phone number and the 6-digit code we text you. There’s no password, and a new number creates an account. Your data is scoped to that account.
3. Set your targets
Log a weigh-in and set your daily calorie and protein targets and goal weight. Today tracks everything against these. You can also start a cut, bulk, or maintenance phase to see whether your weekly rate of change is on track.
4. Log from wherever you are
Snap a meal, type “158.2 this morning”, or ask the agent “what should I eat for dinner?”. To lift on a plan, open Train and start a mesocycle (see Training).
claude mcp add --transport http skcal https://app.skcal.fit/mcpThen ask your agent things like “what’s my status today?” or “log 160 lb.” See Install the MCP server for Claude, Claude Code, and ChatGPT.
npm install -g @skeptrune/skcal
skcal login
