ALTTO: a custom operations app and website
For ALTTO, a bar & restaurant in Rionegro (Antioquia, Colombia), we built two connected things: an operations app for the day-to-day of the venue and a public website that shows the menu and events straight from the same data.
A hospitality business that needed order
The daily operation of a bar & restaurant is spread across reservations, tables, events, staff and the till — usually in notebooks, chats and loose spreadsheets. ALTTO wanted a single tool for all of it — usable from the phone — and its own web presence that always shows the current menu and agenda, without maintaining two places by hand.
The operations app (PWA)
An installable app that runs on the phone like a native app, without going through an app store.
Reservations
Logging and tracking of reservations, with a clear view of the day.
Tables
Table status in real time during service.
Event agenda
Event planning that is also published on the website.
Finances
Revenue and cash in a dashboard with the view of the business.
QR payment
Payment by QR (Nequi / Bre-B) integrated into the workflow.
Time clock
Staff clock-in and clock-out, recorded per person.
Roles & permissions
Separate access for management, partners and the till.
Two-factor (2FA)
Protected login with two-step verification.
Bilingual
Interface in Spanish and German, depending on the user.
The public website
The site altto-rionegro.com is not a disconnected static page: it reads the menu and events from the app's own database, on the same server, so whatever the team changes in management is reflected on the website. It is optimized for mobile and speed, with structured data for search engines and a contact form compliant with Colombian data protection (Ley 1581). On mobile PageSpeed it reaches 100/100 in all four categories — performance, accessibility, best practices and SEO (measured: July 2026).
