**Answer.** Lazyweb Research detected 16 distinct experiments at JustFit (July 2026), and all 16 touch the paywall. [1] In the CTA dataset JustFit runs 11 paywall CTA experiments, but only 3 changed the CTA text — an offer-weighted paywall program. [2] These are observed before/after variations with inferred rationale, not company-confirmed A/B tests.

> All 16 detected JustFit experiments are on the paywall; only 3 of 11 CTA tests changed the button (July 2026).

## The finding

Lazyweb Research detected **16 distinct experiments** at JustFit, **all 16 on the paywall**. [1] In the CTA dataset it runs **11 paywall CTA experiments, only 3 of which changed the CTA text**. [2] JustFit is a pure-paywall fitness experimenter that iterates the offer and layout far more than the button copy.

## How it compares

JustFit's 3-of-11 CTA-text-change rate places it firmly in the offer-weighted cluster with Peloton (3 of 12) and Impulse (1 of 14).

| App | CTA experiments | Changed CTA text |
|---|---|---|
| JustFit | 11 | 3 [2] |
| Peloton | 12 | 3 [3] |
| Elevate | 10 | 7 [4] |

## How to apply it

JustFit is a benchmark for a fitness paywall that leaves the CTA copy largely fixed (3 of 11) and tests the offer instead. If your fitness app fixates on button wording, JustFit reinforces the pattern — seen across Peloton and Impulse too — that offer structure is where this category concentrates its testing. [2]

## Caveats

All figures are observed variations with LLM-inferred rationale, not company-confirmed A/B tests — no lift is measured. [1] CTA claims use the 795-experiment CTA dataset. [2]

## The numbers

| Stat | Computed from |
| --- | --- |
| 16 distinct experiments; all 16 on the paywall | company_total:justfit (value 16; paywall 16) |
| 11 paywall CTA experiments, 3 changed CTA text | paywall_cta_by_company justfit 11/3 |
| Peloton 12 CTA experiments, 3 changed CTA text | paywall_cta_by_company peloton 12/3 |
| Elevate 10 CTA experiments, 7 changed CTA text | paywall_cta_by_company elevate 10/7 |

## Methodology

Universe: 16 distinct JustFit experiments (11 CTA experiments) within 4,814 detected diffs / 795 CTA diffs, July 2026. Extraction: LLM-inferred rationale on observed variations. Caveat: detected variations only, never confirmed A/B tests.
