**Answer.** Lazyweb Research detected 18 distinct experiments at Photomath (July 2026), of which at least 14 touch the paywall. [1] In the CTA dataset Photomath runs 12 paywall CTA experiments, 8 of which changed the CTA text — a paywall-heavy program in the homework-help category. [2] These are observed before/after variations with inferred rationale, not company-confirmed A/B tests.

## The finding

Lazyweb Research detected **18 distinct experiments** at Photomath, with at least 14 on the paywall. [1] In the CTA dataset it runs **12 paywall CTA experiments, 8 of which changed the CTA text**. [2] Photomath is a paywall-concentrated experimenter in the homework-help category, iterating the button copy on two-thirds of its detected CTA tests.

## How it compares

Photomath's 8-of-12 CTA-text-change rate is on the higher end of the education cluster, well above Quizlet (2 of 9). It signals a program that treats the CTA wording as a primary lever.

| App | CTA experiments | Changed CTA text |
|---|---|---|
| Photomath | 12 | 8 [2] |
| Kahoot | 16 | 8 [3] |
| Quizlet | 9 | 2 [4] |

## How to apply it

For a homework-help subscription, Photomath is the benchmark for CTA-forward paywall testing — two-thirds of its detected CTA experiments move the button copy. Pair a copy test with an offer test to attribute movement. All are detected variations, not proven winners. [2]

## Caveats

All figures are observed variations with LLM-inferred rationale, not company-confirmed A/B tests — no lift is measured. [1] Surface splits are lower bounds (screen category unlabeled on 1,425 of 4,814 experiments). [cat_null] CTA claims use the 795-experiment CTA dataset. [2]

## The numbers

| Stat | Computed from |
| --- | --- |
| 18 distinct experiments; at least 14 paywall | company_total:photomath (value 18; paywall 14) |
| 12 paywall CTA experiments, 8 changed CTA text | paywall_cta_by_company photomath 12/8 |
| Kahoot 16 CTA experiments, 8 changed CTA text | paywall_cta_by_company kahoot 16/8 |
| Quizlet 9 CTA experiments, 2 changed CTA text | paywall_cta_by_company quizlet 9/2 |
| 1,425 of 4,814 experiments have no screen category | screen_category_null_on_experiments (1425/4814) |

## Methodology

Universe: 18 distinct Photomath experiments (12 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.
