A baby monitor app can suit a family with two available compatible devices and an internet connection tested in the rooms they use. A dedicated radio monitor may suit a permanent nursery setup with a separate receiver. Start with what will be available throughout each nap.

One device stays with your baby, the other stays with you. Install Luna on both iPhones or iPads; each needs iOS / iPadOS 15+ and internet.

When an app can make sense

Luna needs two compatible iPhones or iPads running iOS or iPadOS 15 or later, with internet on both. Its App Store listing supports Wi-Fi and mobile connections. One device stays by the baby; the other becomes the parent station.

A spare device already at home can make this convenient. Borrowing someone's everyday phone creates a different routine: that phone must remain available for monitoring when its owner needs to make calls, leave home or work. Decide which device will stay in the nursery before treating an app as your regular setup.

What a dedicated radio monitor changes

A model with a direct radio link between its baby and parent units can operate without internet, depending on its design. Its usable range is limited by distance and the building. Walls, floors and surroundings matter; an advertised outdoor range does not tell you how it will perform across your home.

A dedicated baby unit can stay in place, while its receiver is available specifically for monitoring. You still need to check power for both units. A rechargeable parent unit does not mean the baby unit has battery backup. Read the particular model's instructions before assuming it will work during a power cut.

Treat Wi-Fi cameras as a separate option

Buying physical hardware does not automatically remove the need for internet. Connected cameras may need an internet connection for app access. Some combine that with a direct connection to their own screen. Check how each viewing mode works and what remains available if the router or internet connection stops working.

Compare the full cost of your setup

Consider paid app features, any missing second device, chargers and a suitable stand. Reusing a phone avoids another device purchase only if that phone is compatible and can remain available. If you need to buy one, include it in the comparison from the start.

Mobile data allowances and roaming charges can also affect the cost. For dedicated hardware, check what comes in the box and whether batteries or replacements are extra. Connected cameras may offer paid features or subscriptions. Compare the equipment and functions you would actually use, rather than assuming one category is always cheaper.

Test the setup where you will use it

Try your actual rooms with doors closed and your intended settings. Check sound, volume, any video and the available connection-loss and low-battery warnings. Repeat this after changing rooms or networks. Keep devices and cables out of the baby's reach. A responsible adult should remain nearby and able to respond promptly.

Before you start

  • Will every required device be available for the whole session?
  • Have I checked the connection and power in the actual rooms?
  • Have I included equipment, paid features and mobile data?
  • Does everyone caring for the baby know who holds the receiver?

A few more questions?

No. An available spare phone can change the calculation considerably. If you would need to buy a compatible device, compare that complete cost with dedicated hardware.
