**Answer.** Onboarding is nearly 3x longer than sign-in. Across tracked flows, onboarding runs a median 11 screens (n=129) while sign-in runs a median 4 (n=110) [1]. Sign-in is the shortest of the core account flows — averaging 4.5 screens — because returning users just need to authenticate [1].

> Sign-in runs a median 4 screens vs 11 for onboarding — the leanest core flow tracked (n=110 vs 129, July 2026).

## The finding: sign-in is the shortest core flow

Sign-in flows (110, matching 'sign in'/'log in'/'login') have a median of 4 screens and average 4.5, ranging 2-15 [1]. That's the leanest of the account flows, well under onboarding's median of 11 [2]. It makes sense — returning users only need to authenticate, sometimes with a password reset or 2FA branch that stretches the tail to 15.

## Where sign-in sits among core flows

| Flow type | Flows | Avg | Median |
|---|---|---|---|
| Onboarding | 129 | 13.9 | 11 [2] |
| Sign up | 87 | 6.3 | 6 [3] |
| Sign up with phone | 12 | 7.3 | 7 [4] |
| Sign in | 110 | 4.5 | 4 [1] |

Sign-in is consistently the shortest; onboarding the longest.

## How to apply it

Keep sign-in ruthlessly short — 4 screens is the median and there's no upside to length here. If yours runs long, look for avoidable branches (forced 2FA setup, marketing interstitials) that belong elsewhere. Reserve your screen budget for onboarding, where added length can pay off in personalization.

## The numbers

| Stat | Computed from |
| --- | --- |
| sign in 110 flows avg 4.5 median 4 range 2-15 | flowtype_sign_in |
| onboarding 129 flows avg 13.9 median 11 | flowtype_onboarding |
| sign up 87 flows avg 6.3 median 6 | flowtype_sign_up |
| sign up with phone 12 flows avg 7.3 median 7 | flowtype_sign_up_with_phone |

## Methodology

Universe: 2,468 tracked flows; sign in (110), onboarding (129), sign up (87), phone sign-up (12) matched by lower(flow_name) families. Screens per canonical flow. Caveat: LIKE families differ from exact-name counts.
