### 1/5 — Per niente utile

*2016-07-21, version 2.2*

App molto molto confusionaria! Per avere qualche dubbio in più sulle luci è fatta apposta

### 2/5 — Wording is wrong, lights questions unfair

*2016-02-07*

Just paid £5.99 for this - the lights questions are very confusing, poorly worded and technically impossible.

Example: several flip cards show stern AND sidelights that you shouldn't be able to see in real life, even exactly at 112.5deg relative aspect. Have lots of officially approved paper flips cards and have never seen this before. If you're a beginner then don't use this as you won't understand where the errors are and will end up very confused when you come to your exams - or worse when navigating crowded seas at night for real.

Secondly, the wording is very poor and not precise.   The answer to one of several being along the lines of 'a tug boat smaller than 50m with a tow smaller than 200m, skewed to port'

Official terminology should be more like 'Power Driven Vessel, less than 50m in length, underway, making way, towing, with the total length of tow less than 200m, observed from a port aspect'.

If you use this type of confusing and frankly incorrect language to try and pass any exams, leisure or commercial, you will not pass.

Disappointed.

PS. I'm a commercial Yachtmaster and Instructor.

### 1/5 — Insoddisfazione

*2016-01-10, version 2.2*

Usato stamattina per soli 5 minuti..
Comprato l'app. anche se molto cara per faciliare lo studio per la patente nautica, ma purtroppo risulta insoddisfacente per le spiegazioni e domande proposte molto differenti rispetto al classico libro di studio "patente nautica" fornito dalle scuole nautiche e quindi per me risulta peggiorare e confondere l'apprendimento.
Se potessi avere indietro i soldi spesi (non indifferenti) visto l'immediato inutilizzo. Grazie

### 2/5 — Così così...

*2015-01-28, version 2.0*

Idea buona ma con grossi problemi di grafica . Nei quiz le imbarcazioni non ruotano e l'immagine é fissa quindi risulta inutile. A questo punto non vale la cifra spesa.peccato

### 2/5 — No ios8

*2014-10-08, version 2.0*

Su ios8 non funziona, va bene su ipad1 ios5

### 4/5 — Lights and shapes

*2014-07-17*

This is a handy app with great visuals.  Some of the English is dicey.

### 1/5 — No

*2014-01-22, version 1.3*

Durante i test l'applicazione va continuamente in tilt, dovendo ogni volta ricominciare.
AGGIORNATE!!!!

### 1/5 — Non funziona.

*2013-12-22, version 1.3*

Applicazione costosa ma almeno fate in modo che funzioni. Durante i quiz l'applicazione si chiude e bisogna ricominciare aprendo di nuovo tutto. Fate un aggiornamento per correggere grazie.

### 3/5 — Va in crash troppo spesso

*2013-07-26, version 1.2*

Per essere una app da 9 €. Buona l'idea ma alla fine un po' scarna per il prezzo richiesto.
