Official Deployment

LiftShift has one canonical hosted instance:

  • Canonical domain: https://liftshift.app

Deployments on any other domain are unofficial. Unofficial deployments may be modified and may not follow the same security practices. Do not assume an unofficial deployment is trustworthy with any credentials.

Attribution Requirement

Public deployments must include visible attribution to the upstream project.

Minimum acceptable attribution:

  • Link to official site: https://liftshift.app
  • Source link: a publicly accessible link to the Corresponding Source for the exact version running

Attribution must be reasonably discoverable during normal use (for example: footer, About modal, or Settings). Removing, hiding, or obscuring attribution is treated as non-compliance.


Quick Start

<div align="center"> <img src="./frontend/public/images/steps/Step1.avif" alt="Export data from Hevy app" width="200" /> <img src="./frontend/public/images/steps/Step2.avif" alt="Upload CSV to LiftShift" width="200" /> <img src="./frontend/public/images/steps/Step3.avif" alt="Explore analytics dashboard" width="200" /> <img src="./frontend/public/images/steps/Step4.avif" alt="Get real-time feedback and filter data" width="200" /> </div>
  1. Select your platform (Hevy / Strong)
  2. Hevy: Choose your body type + weight unit, then Continue to login/sync (email+password or Pro API key), or import CSV. / Strong: Choose body type + unit, then import CSV
  3. Explore your analytics across Dashboard, Exercises, and History tabs
  4. Get insights with real-time feedback and flexible filtering

Strong CSV imports support common export variants, including:

  • Semicolon-delimited (;) files with quoted fields
  • Unit-suffixed headers like Weight (kg) and Distance (meters)

Troubleshooting

If you see this error:

"We detected a Hevy workout CSV, but couldn't parse the workout dates. This usually happens when the Hevy export language isn't English. Please switch Hevy app language to English, export again, and re-upload."

Do the following:

  1. Switch your Hevy app language to English
  2. Export your workout CSV again
  3. Re-upload it to LiftShift
<div align="center"> <img src="./frontend/public/images/steps/step5.avif" alt="Set Hevy export language to English" width="260" /> </div>
