Hol Horse

In most riding schools and boarding stables, care tracking still relies on paper books left in the tack room, Excel sheets emailed between the manager and the owners, WhatsApp messages to remind the next vet visit, and Google calendars scattered across instructors. A typical 30-horse stable runs around 150 care events a year: several hours of admin per week, at least one missed appointment per month.

Forgotten dewormings, owner disputes, late invoices, no real-time view of which horses are available for lessons, manual planning rebuild every season. The manager bears the full mental load alone, and any slip-up costs them either a relationship with an owner or a chunk of revenue.

Three founding choices. First, mobile-first: the app is used standing, with gloves, in the half-light of a tack room at dawn. Generous touch targets, readable dark mode, everything reachable by thumb. Second, 100% local: every piece of data stays in the user's phone or computer, inside the browser's internal vault (IndexedDB). No server, no cloud, no account, no data sent over the Internet. Privacy by design, minimal attack surface. Third, all-in-one: horse profile, health calendar, one-off events, owners, customisable care types, Excel import / export, JSON backup, bilingual FR / EN.

An installable PWA pinned to the home screen like a real app. The 'This week' dashboard surfaces urgent care events immediately, grouped by horse, with a red / orange / green colour code. Four-tab horse profile (identity, care, events, notes), photos auto-compressed to 80 KB, documents stored locally up to 5 MB, monthly calendar with icons. The smart Excel import recognises non-standard columns heuristically and normalises dates and genders. The Excel export produces five tabular sheets to hand to the vet or accountant. The JSON backup is integral, photos and documents included.
