**Answer.** Both surfaces exist on both platforms, but the volumes flip depending on the surface. Mobile has more signup/sign-in screens (811) than web (643), while web has more checkout screens (296) than mobile (114) [1]. That matches the platform economics: mobile front-loads account creation, web carries heavier explicit checkout. Design each surface for where the volume actually concentrates.

> Web has 296 checkout screens vs 114 on mobile, but mobile has 811 signup screens vs 643 on web — Lazyweb Research, July 2026.

## Finding: signup leans mobile, checkout leans web

The two monetization-adjacent surfaces split in opposite directions:

| Surface | Mobile | Web |
| --- | --- | --- |
| Signup / sign-in | 811 | 643 |
| Checkout | 114 | 296 |

Mobile carries more account-creation surface; web carries more explicit checkout surface [1]. This is consistent with mobile monetizing via in-app paywalls (trial-start rather than a checkout page) while web routes users through a dedicated checkout.

## How to apply this

On mobile, invest in the signup/sign-in surface and the paywall — that is where the screen volume and the experiment leverage sit, and checkout is comparatively rare [1]. On web, treat checkout as a first-class surface with real design attention, since it is the heavier surface (296 screens) and the natural monetization endpoint. Don't assume a mobile app needs an elaborate checkout page — its equivalent is usually the paywall.

## Caveats

These are labeled-screen counts across two distinct corpora that mostly cover different companies, not matched-product comparisons [1]. Mobile counts come from a screen-category join and web counts from screen_type labels, so the definitions are not identical. Use the direction of the split, not the exact ratio.

## The numbers

| Stat | Computed from |
| --- | --- |
| Mobile 811 signup/sign-in & 114 checkout; web 643 signup & 296 checkout | signup_checkout_surface_counts_by_platform |

## Methodology

Universe: mobile canonical screens and web labeled screens for signup and checkout, July 2026. Method: count screens per surface per platform. Caveat: two distinct corpora with non-identical labeling; use the direction of the split.
