Just a few weeks ago, Apple came out and said it was going to reject iOS applications that access the host device’s Unique Device Identifier (UDID) code. This makes it very difficult, if not impossible, for developers to test and track their applications.

UDID codes are also used to help marketers target ads, which helps improve payouts for developers. Basically, this is a major inconvenience for developers who want to sell their apps in the App Store (and make some money off of them).

Though little can be done about it, there are some solutions out there that can help ease some of the strain, one of which is the LeadBolt Visitor Match tracking feature that the mobile advertising company released last October.

Visitor Match, which was built to work across a wide range of platforms, including the Android and iTunes app stores, gives advertisers a way to automatically track mobile conversions in a quick and convenient manner with highly accurate results. According to LeadBolt, the Visitor Match algorithm is able to produce a 98.7-percent accuracy rate for server-side and other conversion pixel events.

Most importantly, Visitor Match is able to track conversions even if a UDID is not present, which really helps set the feature apart and gives LeadBolt users a leg up now that Apple has completely rejected UDID-based apps.

In addition, LeadBolt just made available its iPhone advertiser software development kit (SDK) in a non-UDID version, which should also help users adjust to Apple’s recent changes.
