I think you can't do Adaptations and definitely not Long Coding in the standard app so it's mostly for reading and clearing fault codes which is probably only 10% of what it can do on the Pro mode. Not sure though I got Pro since the beginning and it's by far the best money I 've spent on the car. PRO mode basically offers everything I was using in VCDS (adaptations, long coding, faults, and even live data) in a much more intuitive environment, without the trouble of carrying laptops with me and at a fraction of the VCDS cost. If you want to try out different tweaks like you seem you do, I'd say buy PRO version + dongle and enjoy. I honestly think OBDEleven might have well killed the enthousiast's market share of Ross Tech (VCDS).
