Hi,
I have tried to contact hexis support multiple times, nobody contact me back. At the moment I am to start the process to get my money back. The idea sounds amazing, the reality is far from what is promised. Little details which could be ignored if the rest works well (like for example no option to set start day of the week). But much worse: promised and advertised integration with Apple Health is not working (no data flow into hexis; instructions in video show more data points than what is actually available when connecting hexis & Apple Health - only 3 data points available in my case). Even when you skip (or do not log a meal) hexis keeps to report that your calories deficit reduced (like if I ate anything - amazing I will have tons of energy without spending any money on food!).
I was not expecting “scientific precision” when it comes to how much macros per meal etc; understanding that nutrition and how bodies work is too complex to provide totally accurate recommendations. But at the basics for that money would be nice…
I am totally disappointed. And I was stupid enough to go straight for 12 months subscription (no demo nor trial is available)
