Show HN: Quit All, an iOS app with an SOS mode for cravings

Quit All targets the personal habit-breaking market with a distinct focus on pre-emptive craving management, a departure from traditional post-relapse habit tracking. Its 'SOS mode' and integrated features like timers, prompts, and danger-time stats offer a more proactive intervention strategy. While a consumer app, its design principles—identifying a specific user pain point (cravings), offering a unique solution, and integrating platform-specific features (iOS widgets)—are relevant for B2B SaaS. This demonstrates how targeted problem-solving and thoughtful feature sets can create differentiation in crowded markets. The emphasis on user psychology before a negative event is a valuable lesson for designing proactive engagement in any software.
