¿Quién paga? ¿Qué cenamos? ¿Quién empieza? Fingo lo decide en segundos. Cuatro herramientas para decidir en grupo, en una sola app: sin anuncios, sin cuentas y sin conexión. SELECTOR DE DEDOS Todos ponen un dedo en la pantalla (de 2 a 10). Cuenta de tres y la pantalla se llena con el color del elegido. Ideal para decidir quién paga, quién empieza o quién hace el reto. RULETA Crea ruletas con tus propias opciones y guárdalas para la próxima. Elige entre ocho colores, reordena las opciones arrastrándolas y decide cuánto dura el giro. La ruleta vibra con cada casilla que pasa hasta detenerse en el resultado. NÚMERO AL AZAR Escribe o ajusta cualquier rango de 0 a 999,999, o usa uno rápido: 1–100, 1–6, 1–10, 0–1, 1–31. El número aparece en grande y abajo ves tus últimos tres resultados. CARA O CRUZ Lanza la moneda y mírala caer: dorado es cara, plateado es cruz. Tus últimos cinco lanzamientos quedan a la vista. HECHA PARA LA MESA Resultados grandes que se leen desde el otro lado de la mesa, animaciones rápidas y vibración en cada toque. POR QUÉ FINGO • Sin anuncios y sin compras dentro de la app • Sin cuentas: tus ruletas se guardan en tu dispositivo • Funciona sin conexión • No recopila datos ÚSALA PARA Decidir quién paga · Elegir restaurante · Turnos en juegos de mesa · Rifas y sorteos · Retos entre amigos · Romper cualquier empate Porque a veces la mejor decisión es dejar de decidir.

Verdict
The clearest difference is in-app purchases: Fingo at none against Ring Sizer's 10. Ring Sizer's advantage is update cadence (weekly vs every 2 months) and iOS requirement (18.0 vs 26.0). On price, ads and device support there is nothing between them.
