## What is SyncML LITE 4?

SyncML LITE 4 is a niche app which synchronizes iOS contacts with a server or service which uses a standard called SyncML. The app does not support any other synchronisation technology!

So please install this app only if you know SyncML-based synchronisation is what you need! This may be the case when the IT people of your organisation say so, and maybe even explicitly recommend using SyncML LITE to synchronize contacts. In any case, please realize that for using this app, you need to know the URL of your syncml server, the login user to use, and the so called server path for contacts. Only the provider of the SyncML service knows these details and can support you in establishing sync with his SyncML server. We as makers of the SyncML client app cannot! 

By now, SyncML is a legacy standard. It was invented in 2000, and many of that time's feature phones did support it. Since then, it has been largely superseded by other technologies, most notably CalDAV and CardDAV, which iOS supports out of the box without any extra app. But SyncML still exists, and for some older systems, it may be the only way to synchronize. For those cases, SyncML LITE 4 exists.

SyncML LITE 4 is a rework of the former SyncML LITE app, to allow using SyncML on iOS 10 (the original SyncML LITE app only works up to iOS 9). If you also want to synchronize calendar please consider SyncML PRO 4 or Tasks+Cal+Sync 4.

The summary for SyncML LITE 4:
• Free app for contacts-only synchronisation - please consider SyncML PRO 4 or Tasks+Cal+Sync 4 if you also want to synchronize calendar data.
• based on a mature and extensively interoperability tested SyncML engine, which powers many SyncML client and server products for different platforms (libsynthesis).
• synchronizes selected iOS contact stores (address books) to a SyncML compliant server or service in the internet or in the local network.
• can act as SyncML server in the local WiFi network (e.g. to keep really old mobiles in sync with an iOS device)
• has a contacts list for the iOS contacts, and allows quickly assigning/removing contact group membership (that's a new feature in SyncML LITE 4)

Please visit the plan44.ch web page (see support link below) for support and FAQ, as well as documentation for download.
