****Update*** As of 3-14-2022 I have still not heard back from Healthi in response to my refund, although I've provided everything they have asked for. DO YOURSELF A FAVOR & DO NOT PURCHASE THIS APP. There is NO CUSTOMER SERVICE AT ALL!!!!!!!!!!!! BUYER BEWARE !!!! I contacted Healthi about purchasing their app & to see if they had a free trial period. They wrote back & said I would be able to cancel within 30 days of purchase. I'm not thrilled with the app & sent an email requesting a refund.
