Appointment booking
Protect real availability, deposits, and client context.
Each concept starts with a workflow customers already pay for and repeatedly describe as fragile. The first product boundary is deliberately narrow enough to validate before expanding.

Complaint-first product design
Built from repeated failure patterns.
Counts come from one-to-three-star US Apple App Store reviews collected on 2026-07-29. Themes may overlap; app spread matters because a problem repeated across competitors is harder to dismiss as one bad release.

Clear answers
Before you raise your hand.
Is Slotstead available now?
Not yet. Slotstead is a private-pilot validation concept. The current site recruits research participants and does not claim a shipping product.
Does it replace my salon platform?
The first scope is narrower: stable booking, deposits, conflict handling and migration. It is designed to coexist before it replaces anything.
Can it stop every double booking?
No system can promise that. The design goal is to enforce declared constraints and surface sync or override conflicts before they become silent failures.
What does the calendar-conflict audit cost?
The initial audit is free and is used to validate the workflow, not to sell a fake trial.
