SpreadLift vs Hevy, Strong, Boostcamp, Liftosaur and Crucible
SpreadLift does one thing: it runs the lifting spreadsheet you already use, on your phone, in any browser. It keeps the sheet's own percentage and training-max maths, and it gets kg and IPF plates exactly right.
Other apps do other things better. This page tries to show both. Every competitor fact links to that company's own site or app-store listing and was checked on 19 October 2026. Prices change and vary by country, so check the linked page before you buy. Where we couldn't confirm something, we say so instead of guessing.

Where each one beats SpreadLift
Hevy. Choose Hevy if you want a social feed: following friends, liking and commenting on workouts, and copying routines. It also has dedicated Apple Watch and Wear OS apps, a web app, exercise videos, charts, a free plate calculator, and integrations with Strava, Apple Health and Health Connect. It doesn't run percentage-based working sets from a training max. You type the weights in yourself. (hevyapp.com, compare page)
Strong. It has a clean, fast logger, a full Apple Watch app, charts, a warm-up calculator, Apple Health and CSV export. It suits you if you log freely rather than follow a spreadsheet. The plate calculator needs Strong PRO, and you need an account to start. (strong.app, help: account)
Boostcamp. It has a huge program library (14,000+ programs, 130+ designed by coaches), a community feed, and analytics and auto-progression in Pro. It also works offline once a program is loaded. If you don't have a program yet, Boostcamp is a better place to find one than SpreadLift is. (boostcamp.app/features)
Liftosaur. You write and automate your own progression logic in a scripting language. It has many built-in programs, a desktop editor, an Apple Watch app, an API and an MCP server, and it works offline without an account. It also exports to JSON, CSV and text. It's the most flexible option if you're happy to rewrite your program as code. (liftosaur.com, import/export)
Crucible. It's the closest to SpreadLift in spirit. It imports .xlsx/.csv programs, with a review screen before anything is saved, as part of Pro. It also has a native iPhone app, a conditioning engine (Tabata, EMOM, intervals), calendar scheduling and coach tools, and it works offline without an account. Its site says it reads days, exercises, sets, rep ranges, RPE and rest. It doesn't say whether it keeps a sheet's own percentage formulas. Its site also says both "coming soon" and "live" for the App Store, so check availability yourself. (trycrucible.app)
There's also a different product called "The Crucible" (thecruciblefitnesstracker.com), a workout-plus-nutrition web app. It isn't the one compared here.
Where SpreadLift fits
- Your sheet stays your sheet. SpreadLift keeps the spreadsheet's own %/training-max maths, so the numbers you see are the ones the author wrote. Nothing gets rebuilt by hand.
- Plates done right in kg. It gets kg and IPF plates exactly right.
- Nothing to install. It works in any phone browser, and you don't need an account to start.
- Free to try properly. These are free forever: importing your sheet, the first 2 weeks of any program, and 4 calculators. The calculators are the Plate Calculator (kg & lb), Warm-up Calculator, RPE & e1RM Calculator and DOTS Calculator (IPF points).
- Familiar sheet layouts.

If you want a social feed, a watch app or a big program library, one of the apps above will probably suit you better, and that's fine.
Check your numbers and train safely
Whatever app you use, check the weights it gives you against your sheet before a heavy session. Load the bar carefully and use safeties or spotters.
