## What is Arduino Pocket Reference?

Arduino is a tool for making computers that can sense and control more of the physical world than your desktop computer. It's an open-source physical computing platform based on a simple microcontroller board, and a development environment for writing software for the board.

### 5/5 — Amazing and Super Helpful

*2021-10-23, version 3.4*

I love this guide application, it’s so useful and helpful. I learned a TON from just this one guide.

### 5/5 — Pretty nice

*2020-08-09, version 3.3*

Works great no constant ads

### 1/5 — Annoying ads every 15 seconds

*2020-03-06, version 3.3*

I wouldn’t mind if ads were embedded, but this app opens safari every 15 seconds with ads pages, which makes impossible to focus in the information we need. 

DELETED THE APP IMMEDIATELY.

### 1/5 — Suspicious activity

*2020-02-03, version 3.1*

Keeps asking for me to sign in with my Apple ID. Very suspicious. Deleted.

### 1/5 — Still has ads

*2019-08-15, version 3.0*

Paid the .99 to remove ads but ads did not go away. What’s up with that?

### 1/5 — Don’t waste you money

*2019-08-10, version 2.9*

Keeps locking up and full of adverts

### 1/5 — Would be great if...

*2019-07-10, version 2.9*

Constantly asks for password. Adverts takes up usable space, afraid if purchased annoyances would too..

### 1/5 — Not really a reference

*2018-02-11, version 2.5*

I was looking for a replacement for “Arduino Companion”, which doesn’t work with iOS 11. Something to look up functions and libraries, kinda like a reference. This ain’t that.

### 1/5 — Adds Removal No Go

*2018-02-02*

Pay to remove adds, adds go away, restart app, adds be back, pay to remove add, results in restoring purchase for free, adds go away, restart app, adds be back. Now put this in the loop() area of your sketch, and bingo, your first sketch that matches the operation of this app.

### 1/5 — Always ask for iTune password

*2018-01-23, version 2.5*

I don’t understand why this app always asks me to enter my iTune password,
I began having concern about safety to use it
