I keep in touch with them by Skype, but the young ones are not really old enough to concentrate on it and we're often in quite different timezones, so it's not often it can be very spontaneous. We'd like to have some way that we can record short video messages of things we're doing and send them to each other. It needs to have an iPad app that is simple enough for a three-year-old to use with help and for a five-year-old to use without help; it needs to have an Android or web client, preferably one that doesn't require an Apple ID; it needs to be able to record a short video and send it to someone. As far as I can tell, iMessage requires Apple kit (there is an Android app but it sends all your messages through a server in China...) and Whatsapp works on iPhone but not iPad. What can you suggest?
