Synced YouTube guitar tutorials

A minimalist music-study portal: pick a song and learn from a synced split view — YouTube player beside a scrollable frame grid that highlights and auto-scrolls to the current moment as the video plays. Read-only, no login, instant.

Condominium administration made simple — a Forge prototype

Financial management, assembly voting, maintenance tickets, common area booking, and resident communication. Concept stage — planned to be scaffolded through Forge.

Photographers and photography lovers, organized by theme, exchanging knowledge

A second Forge app-creation test, generalizing sdb-surf's own scaffolding approach beyond surf — any subject, any theme, connecting photographers and enthusiasts around it. Skeleton only: identity + menu shaped, real features not built yet.

Automação comercial e contábil — codinome mini-sap

Third Forge app-creation test (2026-08-01): a contábil-based business-automation system. Its first real feature — Lançamentos — simulates despesas/receitas/saldo month by month across years for a small delivery-lunch restaurant (Cozinheiro · Caixa/Logística/Pedidos · Entregador), with Lucro = Faturamento − Despesas as the core mini-sap principle other apps (gestão-mão-de-obra, loja-de-conveniência, ...) are expected to reuse. Remaining menu areas (Clientes, Fornecedores, Contas a Pagar, Contas a Receber, Relatórios) are still identity-only.

Spec-driven pet & family health app

Vaccination schedules, vet appointments, nutrition tracking, exercise logs, and health reminders — built on the shared lib/domain person model + AppShell/TComponents, with an admin panel exposing the business/auth/governance tables as TGrids. Live in production since 2026-08-31, including a real Receituário document-authoring feature (2026-09-04).

Human-family-health side of Nino Care

Draft catalog entry — registered in the tonneworg.app ecosystem registry (category Pessoal, status design); no dedicated frontend of its own yet. Reserves its place in the Cuidadores e Médicos tab.

Clinical + health-insurance billing MVP

Real MVP v0.1 — a Forge-scaffold app rewired to show live consultorio schema data (operadora, patient, professional, convenio, consulta, operadoraBatch) via Sentinel's own bridge, no bespoke backend. Falls back to honestly-labeled demo data when Sentinel's bridge is unreachable (e.g. a real public visitor) — same pattern as nino-pqd's own Sentinel-linked tables.

Lançamentos contábeis e relatórios

Draft catalog entry — no Forge project, code, or schema exists for this app yet. Reserves its place in the Área Financeira tab alongside the ecosystem's other Automação Comercial apps.

Payroll e obrigações trabalhistas

Fill a freelance payment receipt, export as PDF — nothing saved

Scaffolded 2026-07-31 through Forge's simplest default pattern (no template borrowed from another app). Fills a Recibo de Pagamento a Autônomo — origin and target can each be a CPF or CNPJ person — and exports the result as a PDF. Session-only for now; a later pass links it to tonnew-org's lib/domain person model.

Compose an itemized price proposal, export as PDF — nothing saved

Scaffolded 2026-09-02, cloned from Recibo Fácil's own proven pattern. Fills an itemized service proposal (prestador/cliente, each CPF or CNPJ, line items, named % surcharge factors — access difficulty, danger, unhealthy conditions, etc. — for transparent, justifiable pricing) and exports the result as a PDF, with a client 'De acordo' approval line. Session-only for now; a later pass links it to tonnew-org's lib/domain person model, same as Recibo Fácil's own plan.

Centro de atividades — um centro religioso, com calendário de grupos, cursos e eventos

Real Forge app skeleton (2026-08-28) — the first real instance of the general centro_eventos organizational-entity template, built here as a religious center of activities (groups, instructors with substitutes, courses, each with their own calendar frequency, plus recurring/traditional dates over one-off events). AppShell + lib/ui-controls, dashboard driven by the new shared TCalendar component (year/month/week/day views). Real schema/backend not yet wired — this is the UI skeleton + calendar POC only.

Remoção de abelhas — chamados + recibo de serviço

Client site for a bee-removal service: service calls tracked by client/neighborhood/status, plus a printable service receipt. Requested 2026-08-04; no prior code, docs, or repo trace exists for it yet (confirmed via a full-repo search) — this entry only registers the name and reserves its place in the catalog.

The app creator behind every product here

Principia's app-creator — designs, scaffolds, and exports runnable apps with a generated backend and auth, built on the shared lib/ui-controls component set. Every product on this page, live or planned, either was or will be built through it.

Watches, tests, and shields every app in the ecosystem

"Sentinel vai lhe mostrar com quantos erros se faz um sistema."

Principia's observer — monitors the fleet, runs the regression battery, mirrors the OpenSpec workflow, and turns in-session proposals into changes. Deployed 2026-08-03 to Fly.io as its own service (app-admin.sqlite + userTests/ on a persistent volume); the monorepo-scanning features (OpenSpec mirror, work-folder scan) are deliberately not bundled into this public image yet, so they report empty rather than crash — the fleet/test-execution/admin-config core is fully live.
