“AR Danik Circuit Engineering” will help your child to learn how to create and explore various circuit boards with the use of augmented reality technology. App allows you to create boards without costs, safety problems and inconveniences with electric components. The circuits are designed by arranging printed paper component cards and pointing the mobile device camera from the application. At the moment list of electrical circuit components includes: one battery, two switches, six incandescent light bulbs, four resistors, one electric motor, testing component for conductors and dielectrics, six wires and earthing. These components allow to set up sequential, parallel and combined boards. Voltage and current intensity of every circuit can be measured with voltmeter and ammeter. Besides, resistances of light bulbs, resistors and electric motor are controllable; battery has 4 alternative voltages. Attention! Technical requirements for devices: tablet or smartphone with camera, min. 700 mb of free space, 1 GB RAM, iOS 9.3.5 and higher.

¿Tienes que preparar un Spelling Bee y no sabes cómo practicar en voz alta? Spelling Bee Trainer convierte cualquier lista de palabras en inglés en una sesión de práctica oral: la app dice la palabra, tu la deletreas hablando, y la app va mostrando cada letra en pantalla mientras la escucha — igual que ocurriría delante de un jurado real. Además, te va corrigiendo! CÓMO FUNCIONA - Crea una o varias listas de palabras (para cada uno de tus hijos, por asignatura, por dificultad, o por lo que necesites) - Añade las palabras a mano, o haz una foto a la lista de palabras que tienes que estudiar y la app extrae el texto sola, luego te da la opción de añadir o no añadir cada una de las palabras identificadas - Pulsa jugar, y practica: la app dice la palabra, tu la deletreas, y ves las letras rellenándose en tiempo real - Si te equivocas, puedes intentarlo de nuevo sin perder lo que ya llevabas bien - Sigue tu progreso: cuántas palabras llevas acertadas y cuántas quedan PENSADA PARA CUALQUIER LISTA No hace falta que sea para un Spelling Bee escolar — sirve para memorizar vocabulario de cualquier examen o lista de palabras en inglés. PRIVACIDAD Todo el reconocimiento de voz y de texto se procesa en el propio dispositivo. No creamos cuentas, no mostramos anuncios, y no recopilamos ni compartimos tus datos con nadie. Los detalles completos están en nuestra política de privacidad. Pero vamos, todo ocurre exclusivamente en tu dispositivo. GRATIS PARA EMPEZAR Puedes crear hasta 3 listas con hasta 10 palabras cada una sin pagar nada — de sobra para probar la app de verdad. Si quieres listas y palabras ilimitadas, puedes desbloquearlo con una compra única dentro de la app. Esperamos que la disfrutes!!
