castells.app

What It Is

Castells.app is a management tool for Catalan human tower teams (colles castelleres), with the relevant app rights held by Rental Ninja SL. It covers core workflows such as rehearsals, tests, lineups, events, and statistics, supports iOS, Android, and Web, and emphasizes real-time synchronization across devices within the same team. The official website states that the product has been “used over the past 7 seasons,” indicating that it is not merely a conceptual tool but has accumulated practical use in real-world scenarios.

Core Features

The product is highly vertical in its design. The rehearsal module supports real-time tests, editable ordering, change history, and test status. The member module records roles, gender, height, nicknames, positions, and technical groups. The lineup module covers tronc, canalla, conflict checks, and saved lineups. The pinyes module provides position editing, floor notes, and historical records by castell (marked as beta). In addition, it includes a complete castells catalog, fatigue/ability calculations, duration estimates, attendance statistics, a media library, video comparison, evaluation forms, push notifications, message templates, and event reminders. On the permissions side, the official site clearly provides 30+ fine-grained role-based flags, with gated access for modules such as tronc, canalla, pinyes, and media, making it well suited to collaboration within technical teams.

Pricing and Integrations

The official website does not publish plans or pricing; it only offers an “request access” option and states that discussions are handled case by case with each team. The terms mention that fees may be introduced in the future, but users will be clearly informed before any charges apply. For integrations, the terms list Google Play Services, Google Analytics for Firebase, and Sentry. The product page also mentions CSV import/export and synchronization with Appsistència. No public API, webhook, or developer documentation was found.

Pros and Cons

The strengths are its focused use case, complete feature flow, real-time collaboration, and relatively mature permission design, making it highly supportive of rehearsal management and technical decision-making for human tower teams. The drawbacks are its extremely narrow industry applicability and limited public commercial information. In terms of security and compliance, it only states that personal data is processed, with a lack of details on encryption, backups, GDPR, or audits. Some features are still in beta.

Who It’s For and Access from China

It is best suited for the boards, technical teams, rehearsal leaders, and media/communications members of colles castelleres. It is not suitable as general-purpose team management software. The main text provides no basis for assessing access from China, so the status is unknown.
