### 5/5 — Mi salvación para Poteger Mis Uvas de Mesa

*2017-07-14, version 2.3*

Soy Huerto Urbano Luis Servia y tengo mi propio BLOG y Canal de YouTube y mis dos Cultivos Preferidos son mi Parral de Uvas de Mesa y Calabazas del Peregrino.
El año pasado puse dos Ahuyentadores de Pájaros y Aves por Ultrasonicos Digitales que reproducen los Sonidos de Aves de Presa y espántan a los pájaros que se comían mis uvas.
Hace tres año las embolsaba pero como no encontraba bolsas del tamaño de los racimos que consigo gracias a un buen amigo que me dejó dos Aparatos de Ahuyentadores de Pájaros y Aves pude salvar ni cosecha en un 100 %.
Ante la reclamación injustificada de un par de vecinos que me denunciaron a la Policia Municipal y para regular los Equipos me compré vuestra APP - dB - Niose Meter para Iphone e IPad pude regular dada sus Grandes Prestaciones, Su Facilidad de Manejo, Datos de Localizaciín del Lugar de su Toma, Poder Realizar Fotografías, Vídeos y Notas de Voz voy a Montar un Vídeo de mi Campaña de 2017 para que se entere el Muy Ilustre Sr. Alcalde de Fraga, Sus Servicios Técnicos y los Vecicon Que se Quejan Sin Razón que mi Emisión de Sonidos CUMPLE CON LA NORMATIVA VIGENTE.
Le recuedo al Sr. Alcalde que tengo pendiente una Visita que pedí Formalmente y Legalmente hace un Año en SOLICITUD DE AMPARO y que pese a casi una veintena de recordatorios aún la tengopendiente.

### 5/5 — Noise meter

*2017-06-05, version 2.3*

This is an excellent app

### 1/5 — Enttäuschung

*2017-05-17, version 2.3*

Es ertönt eben kein Alarm, wenn die eingestellte Grenze erreicht wird. Unbrauchbar für mich. Leider.

### 5/5 — Not a ranked app but the best

*2016-07-26, version 2.3*

I searched long to find a decibel app and stumped on this one and truly the best:
It gives you a 40s read to compute all the data information about the decibels Noise around you with map location recording video photo and annotation with history and dB plot in chart. Just missing the capability to print report cards and save to PDF - maybe next update?

### 5/5 — 挺专业的，还不错

*2016-05-31*

就是不知道如何导入电脑，有点麻烦，我的意思是，整个文件导入电脑
