Really confusing this much sygic apps and in app purchases

I have Sygic Brazil that I bought a long time ago. There is an app purchase promotion for me to upgrade to world+traffic lifetime. However in this app the price for world+traffic lifetime is more expensive. My doubt is if I can use the sygic store purchase in any app of sygic or just in the one that I bought
To make things worst there is on sygic car navigation that you need to bought for a dolar and pay this in app worldwide+traffic too
