The iBurn App does not run at all without Google Play Services. You just get a dialog on launch that requires Google Play Services before continuing. This seems odd for a largely offline app. I think you simply need to disable some check for Google Play Services and iBurn should work fine.
As an aside, apps like Signal and WhatsApp that make serious use of Google Play Service for Google's notifications server employ workaround to function without Google Play Service. These Apps do loose some functionality, Signal burns slightly more battery, and WhatsApp only receives messages when you launch it, but otherwise they work perfectly.
