In the current iOS 7 Beta 1, there is no Voice Memo app, however a leaked image  from a WWDC developer session is making the rounds, showing that the Voice Memo app will make an appearance in a future release. The Beta 1 release note also notes “Voice Memos – Known Issues: The VoiceMemos app is not available in this seed.“, suggesting that Voice Memo should be in there or will be in there in a later Beta version.
