Short answer
Yes — 7-day is the most-advertised trial length by a wide margin: 148 mentions (57.4% of the 258 length-naming CTAs) from 42 distinct companies, two-thirds of all length-advertising companies.source[1]source[2] No other single length comes close on a company basis. If you advertise one trial length, 7 days is the safe, evidence-backed default.
42 of 63 length-advertising companies use a 7-day trial — the clear default — Lazyweb Research, July 2026.

The finding
7-day (including '1-week') is named in 148 of the 258 length-advertising primary CTAs — 57.4% of them, and 7.8% of all 1,886 primary CTAs.source[1] Company-deduped, 42 of the 63 companies that advertise any trial length use 7-day, versus 12 for 14-day, 9 for 3-day, and 7 for 30-day.source[2]
| Length | Companies | Share of 63 length-advertisers |
|---|---|---|
| 7-day | 42 | 67% |
| 14-day | 12 | 19% |
| 3-day | 9 | 14% |
| 30-day | 7 | 11% (upper bound) |
Named examples: PictureThis ('Try 7 days free, then $39.99/year'), Yousician ('Try free for 7 days'), Calm ('Try another 7 days for free').source[1]
How to apply it
7-day is the default because it balances two forces: long enough for a user to build a light habit or see recurring value, short enough that the billing decision arrives before novelty fades. It is also the only length with a citable sample across multiple verticals — in Health & Fitness (7-day dominates at 25 mentions) and Music (7-day is the only common length, 14 mentions), it is effectively the sole option.source[3]
Deviate from 7-day only for a reason: shorter (3-day) for instant-utility apps forcing a fast decision, longer (14-day) for tools that need setup time. Absent such a reason, 7 days is the choice that matches the largest cohort of apps.
Caveats
7-day is detected via (7|seven)[- ]day|1[- ]week regex over button plus adjacent copy, so trials shown only on plan cards are missed. The 57.4% is a share of the 258 length-naming CTAs, not of all paywalls — most primary CTAs (86.3%) name no length at all.source[1] Cross-vertical dominance figures use per-vertical samples that clear n=70. July 2026 pull.

Methodology
Universe: 258 length-naming primary CTAs (of 1,886) across ~800 tracked apps, July 2026. 7-day detected by regex over button plus adjacent copy; company-deduped counts used for prevalence. Per-vertical cuts require n>=70.
