## The short answer

Boostcamp is a free workout tracker with a large library of ready-made lifting programs — 11,000 of them, including coach-designed ones — on iOS and Android, with auto-progression and analytics and no paywall on the programs. phase.fitness does not hand you a program to pick: it writes one from your goal, equipment and constraints, across strength, cardio and calisthenics, and reads each finished phase to build the next. If a known template fits your goal, Boostcamp costs nothing and does it well. If your week needs ordering across modalities, that is what phase.fitness is for.

## What Boostcamp is

A free workout tracker built around a large library of ready-made programs, many of them well-known community and coach-designed templates, with auto-progression and analytics built in.

## When Boostcamp is the better choice

- You want a known template — 5/3/1, GZCLP, nSuns, PPL — and you want to run it as written.
- You do not want to pay anything, which is a completely legitimate answer.
- You mainly want a tracker with good analytics, and the program is secondary.
- You train only in the gym and nothing in your week needs ordering against a long run.

## When phase.fitness is

- No template fits, because your week has lifting, endurance and a skill in it.
- You want the next block written from the one that just ended rather than chosen again.
- You already log in Hevy or Liftosaur, or on a Garmin, and want the plan to arrive there.
- You want calisthenics skills on a progression rather than in a note.

## Frequently asked questions

### Is phase.fitness free like Boostcamp?

No. Boostcamp is free and says its programs are not paywalled; phase.fitness is $34.90 every three months or $104.70 a year. What you buy is a program written and rewritten for you rather than a library to choose from.

### Does Boostcamp plan cardio?

The pages we read describe lifting: programs labelled by strength and muscle goals, and gym tools like a plate calculator and a rest timer. phase.fitness plans cardio and calisthenics in the same program as the lifting.

### Can I keep using Boostcamp's templates with phase.fitness?

Not directly, but phase.fitness's own library holds importable templates, and a program you import can then be adapted phase by phase. phase.fitness also pushes sessions to Hevy and Liftosaur if that is where you prefer to log.
