Getting Started with iSitter

Thanks for trying iSitter.

iSitter is an application which connects 2 iPads or iPhones and allows you to use them as a baby monitor.



iSitter requires a good medium bandwidth signal to work. In Bluetooth mode the devices talk directly, and in WiFi mode they talk through your existing wifi network. iSitter Connect will allow you to use iSitter wherever the 2 devices have a reasonable internet connection.

Remember iSitter requires a constant connection to transmit non delayed audio all the time, other network uses such as browsing and streaming video can cope with intermittent network drop outs a lot better.

Factors that can affect your connection


  • Distance between devices

  • Objects and walls in the line of sight between devices

  • Other devices on the Bluetooth 2.4Mhz frequency (video senders, cordless phones, wifi networks..)

  • Direction that your devices are facing can make a big difference


  • Distance from either device and your wifi router

  • Objects and walls in the line of sight between either device and your wifi router

  • Other wifi networks on the same channel

  • Commercial wifi networks (e.g. Hotspots and Hotels) where inter device communication is banned for security

  • Direction that your devices are facing can make a big difference

  • Stop devices scanning for wifi networks (settings, wifi, ask to join networks = OFF)

iSitter Connect

  • Available internet bandwidth

  • Other users of the internet connection

  • Poor WiFi reception

iSitter won't connect

Under nearly all circumstances iSitter should connect by just pushing the "Baby" button on one device and the "Monitor" button on the other and choosing the right Baby device.

Don't forget you need to give permission on the baby side!

In the event that no connection happens, a bit of troubleshooting will be needed. Note you can run a network test under the help menu (do this on the parent device, with the baby device already running).


• Log both devices into the same iSitter connect account, even if you are connecting locally over wifi the cloud can help your devices find each other. (for free!)
• Try force closing iSitter on both devices (
• If just using wifi is ok - try choose "Wifi" when you activate the baby end.
• Check both devices have a valid internet connection with Safari and try iSitter Connect
• Use the personal hotspot function on the baby device, and connect the parent device to that hotspot.


Bringing the devices physically close and trying a Bluetooth connection is probably the first thing to try. Place the devices within 1m of each other.

Ensure that the bluetooth icon is in the status bar for both devices:

If one or both device doesn't have the Bluetooth icon, you can turn on bluetooth in the settings app.

For this test, you should also turn wifi off.

The 2 devices should now connect, in the event they don't connect I would recommend switching both devices completely off waiting 30 seconds then turning them on again.

If after restarting both devices no connection is occurring, then one of your devices probably needs either hardware service or wiping and restoring (Probably not worth it just to make iSitter work..)


Once you have the bluetooth connection working, you can turn on wifi on both devices. After ensuring that both devices are on the same wifi network and browsing with Safari to check connectivity then move the devices to their required position and try connecting.

NOTE: Some wifi networks don't allow inter device communication for security reasons
NOTE: Rebooting your wifi router may sometimes help

iSitter Connect

As well as the only option when you are trying to go across wifi networks or use cellular data, iSitter Connect can bypass a lot of strange issues with WiFi networks.

Working wifi Wifi Extenders


iSitter can work with WiFi-Extenders or larger WiFi networks but they must be configured to create one 'big' network for everything to work correctly.

If you configure extenders to create their own little mini networks, then things connected will be able to see the internet but not necessarily other things on the network.

In the diagram above, there is one extender (Airport Express) connected using the correct 'Bridge' mode and there is one connected using 'NAT Mode'. This has the following results:

A - connected to the bridge mode express - can be Baby or Monitor
B - connected to the main router - can be Baby or Monitor
C - connected to the NAT mode express - can only be monitor, it cannot accept connections as a baby from device connected to anything other than the NAT express

Sometimes you don't know to which access point your devices are connecting, and they can even switch mid stream, so its worth making sure everything is configured correctly.

Troubleshooting Connection Quality

iSitter requires a continuous data flow between the 2 devices, whilst most people won't experience any issues with their connection sometimes problems can occur.

As of version 2.41 iSitter has some visual feedback on the quality of your signal. Note that this indicator is quite fast to show a bad signal as iSitter adapts to the signal but when the signal improves it will take a longer time to take advantage of the better bandwidth and show a higher reading.


Signal Quality Indicator Bars

The signal quality bars provide an overall measure of "how hard" iSitter is having to work to maintain a continuous timely audio stream. Lower signal bar indication means that iSitter is increasing its audio buffers and reducing audio (and image) quality to try to avoid breaks in the audio.

Buffer / Audio Quality Bar

The length of the buffer bar indicates how full iSitters audio buffers are. This bar turns red when iSitter is resorting to sending audio at half quality.

More advanced indicators.

More detail is available on iSitters connection status, you can display this debugging information by pressing and holding on the camera image on the monitor device.

This real time information is quite useful if you want to move your devices around to get the best signal. Aim for locations which give the lowest possible value for "Latency".

You can also see the last time the connection "glitched" which can be a useful measure.

Does it matter which device in app purchases are on?

Purchases on the App Store are specific to the AppleID on which you make them, and are then available on all devices with that Apple ID or within the same "Family" sharing plan.

iSitter doesn't check the store every time it starts up in case something has changed, this would require typing in your Apple ID password each time and would be frustrating for the users.

You can get it to check again, in 3 ways:

• Trying to make the purchase on the new device would tell you you already bought it, and offer it for free
• Apps should have a "restore previous purchase" button, to log into the store and download any purchases. iSitter has one.
• Re-installing the app from the store will bring down its purchased state

For situations where your devices are not on the same AppleID, or within the same Family, once iSitter connects it temporarily transfers all purchases onto both devices until the next time it is closed.

Can i use iSitter for free?

Sitter works in 2 modes, the “Wifi” and “Bluetooth” work without any ongoing cost on the same wifi network or within bluetooth range – you can pay to remove the ads.

For iSitter Connect which allows connection anywhere there is internet by sending it through a cloud server, thats only free when the servers aren’t busy.

iSitter for older devices

Have an old device and want to use it as the Baby end of the monitor?

A "Baby Only" version of iSitter is available for devices running iOS5 onwards:
