See their website for more information on what the Tempo even is but the TL;DR is
Tempo is the only smart home gym that makes weight training personalized and safe through real-time form corrections and custom workout plans.
This package provides a TypeScript SDK to the (very unofficial) API their mobile app uses.
npm i tempo-fit-api
You will want to copy the .env.example and add your tempo username and tempo password to run the tests.
You must create an instance of Tempo in order to use it.
import { Tempo } from 'tempo-fit-api';
const tempo = new Tempo();
tempo.login({email:'your@email.com',password:'hunter1'});
See tempo.test.ts for a full example of the current usage.
