Short-Haul Flight

iOS Airways welcomes you on our flight from iPhone to iPad.
Please be sure your seat belts are fastened as our captain will go by the speed of light.
If you’re going to leave anything after touch down, please make sure it’s something we’d like to have.

The basic idea …

M2M or machine-to-machine communication, or technology that supports wired or wireless communication between devices. An example of M2M technology might be a set of devices that monitor traffic in a city and communicate the information to the city’s traffic lights in order to regulate the flow of traffic.

There are several ways to establish M2M for sending files from one device to another.

  • iOS device – Computer
    Using iTunes File Sharing or computer software like iExplorer which allows access to app specific folders on an iOS device
  • iOS device – Any device
    Send by E-Mail using Apple’s mail client
    A suitable app must be installed on the destination device to open attachments
  • Send to a cloud storage and share the file
    An app with the original file must support server access with built-in access for well-known providers WebDAV
  • iOS device to another own iOS device
    Transmit via iCloud
    Not all apps support iCloud at the time
    Access is only possible if both devices use the same Apple ID
  • iOS device NAS
    NAS (network attached storage) can be a computer’s hard disk or a hard disk or a USB storage attached to Apple’s Airport router or Time Capsule

Examples …

Here are some apps supporting direct transfer from one iOS device to another even if the destination device is running under a different Apple ID:

  • Tap Forms Database

  • Safety P+V

    Bluetooth and WiFi
  • Air Sharing
    by Avatron
  • Documents
    by Readdle
  • Instashare
    by Lukas Foldyna
    WiFi and Bluetooth

Transfer Methods …

  • WiFi and Bluetooth
    One device acts as a push server.
    Usually the destination device firstly has to accept the connection.
  • WebDAV support
    The iOS device acts as a WebDAV server for a computer.
    On the computer you access the device by entering an URL like (IP address of the iOS device and Portnumber for communication).

Establishing connections …

This description is valid for Phone Drive by 83Technology and explains the different connection methods.

File transfer between Mac or PC

Connect your device to same Wi-Fi network with PC or Mac.
Tap “Sync” icon and select “Mac / PC File Transfer” button to find out your device address.
Web Browser
Enter the IP address on your computer web browser to access file transfer interface.

Mac OS X

Open Finder.
Select “Connect to Server” from the “Go” menu.
Enter the IP address and click “Connect”.
Note : If you do not enable Authentication just select “Guest” and click “Connect”.


From My Computer click on the “Map Network Drive” toolbar button.
Enter the IP address and click “Finish”.

File operations
Click on “Edit” button or swipe right and select the file you wish to perform operations.
Tap on “Menu view” icon to choose file operations. (Copy, Move, Zip, etc)

File sharing to another iPhone or iPad (Bluetooth / Wi-Fi)

Connect both devices to same Wi-Fi network or enable bluetooth.
On of the device tap on “Sync” icon and select “iOS to iOS File Sharing” button to search for nearest device.
Select the device name that found and accept connection for file transfer.

The UIs of assorted apps …

Rate the developer’s approaches to UIs for transferring files.

Instashare …

Instashare is an aptly named utility that lets you instantly share files between your iOS devices and your Mac and Windows PC (Beta).

Sharing is quite simple. Open the app on both iOS devices.
On a device all connectable other devices appear on the right side and the file list on the left side. You transfer files by Drag and Drop from left to right.

Instashare uses WiFi or Bluetooth. An Internet connection is not required.

In addition, you can transfer files of any file type from a Mac to your iDevice, and vice versa. Files received by a Mac appear on the Downloads folder, while those received by an iOS device can be found in Instashare’s local app folder.


Public Wi-Fi …

Sometimes, when using public WiFi for transfering files, problems might occur when starting the file transfer or displaying the list of nearby devices. Instashare is using ports 1000 and higher but public WiFi’s (Coffee shops, Airports, …) may block these ports. Best practice to settle this problem is creating your own WiFi access point which in iOS terms is called ‘Personal Hotspot’.

Personal Hotspot
A Personal Hotspot is one of your iOS devices with a connection to the internet.
This device may act as an access point for an other device that means, the other device does not connect to the internet directly but via the device serving as Personal Hotspot.

Go to Settings – Personal Hotspot and turn the switch to ON.
With your other device you now can connect to the Personal Hotspot in the same way you would connect to any other WiFi network.

Summary …

Instashare is the winner when it comes to a rating of the UI.
Simplicity and intuitive handling is the key to a top rating.

Transfer is only supported for one file at a time.
Selection of multiple files should be offered in an upcoming feature update.

Note (2013-05-02)
At the time I wrote this article PDFs could not be transferred from other apps to Instashare by using the ‘Open in’ command. But this problem was settled by Lukas. So now it works. Thanks Lukas.

Summary …

I myself use the mentioned apps and assessed them all very critically.
Tablets are a new technology (first iPad came in 2007). While the hardware is already grown up the software is still embryonic. Apple’s App Store makes no difference between hobby and professional developers. So for customers it’s not easy to find out the right app. And there is a further problem: the reliability of a developer, the power to refine the product and the energy to survive in the fast growing market of rock-bottom goods.

Most of the users working on an iPad without it’s big brother perceive the desirable features an app should have. But it seems to me that most of the developers are not able to adjust to the market.
