AI 分析

痛点：现有屏幕使用时间工具只做每日限额，无法阻止单次滚动演变成数小时 doomscroll，用户需要按小时重置的滚动限制。

目标用户：iOS 上容易无意识刷 Reddit/社交媒体的重度用户、需要保持专注的知识工作者和学生。

证据：I built this thing because no other screen time app/solution had this feature. It seems to be the first of its kind on iOS. ... Lifetime access is currently 75% off until 05 OCT 2026!!

变现：免费增值 + 订阅/一次性买断；以免费 lifetime 码引流，主推折扣 lifetime 或年订阅。

竞品：Opal、ScreenZen、One Sec、Apple Screen Time

摘要：独立开发者在 r/SaaS 发布 Precursor，核心是按小时滚动限额，而不是每日限额，声称是 iOS 上首个此类方案。产品对标 Opal、ScreenZen、One Sec 和 Apple Screen Time，提供社区免费 lifetime 码，并将 lifetime 买断价打 75% 折扣至 2026 年 10 月 5 日。机会真实但竞品密集，付费意愿尚未由收入或用户付费原话验证。
