The mobile app will tell if you are doing anything wrong and give some advice to fix it, just like a human coach. That helps to follow the proper exercise techniques and avoid traumas as doable. But another valuable thing in benchmarks is comparing the results with the average results of other users our age and exercise patterns. And this big data analytics is not so easy and accessible for a human.
Compared to humans, Zing is a highly intelligent but still algorithm-based app with its limitations. We can't feel the connection and build some relationships with the algorithms, but we aim to bring the way the app interacts with users as close to human interactions as possible. So the only reason Zing might not be your choice is if you prefer to exercise with a personal trainer for heartwarming human interactions.
And talking about the future, we will definitely see a broader set of benchmarks to make users' training more effective and results more measurable. So if you don't mind interacting with Artificial Intelligence, you should give it a go — we have a free trial.
