APP/IT Support When On Boarding as a New Customer

I have been using plain old Zero happily and successfully for a few weeks. I was sent an email with a discount offer to purchase Zero Plus due to Black Friday. The link took me to the APP and a page that said ‘oops something went wrong- refresh’. Reaching out to Big Sky Health informing them of the issue, they responded to the first email with a custom made response (very thankful because this is rare) with assistance that unfortunately failed. Upon writing back (complicated by time zone separation) for further support the issue has now been resolved by uninstalling and reinstalling the APP. I’ve persisted because even prior to the full suite of the APP features being available to me this suits my personal requirements for IF and provides useful data points. IT have provided ongoing support and are happy to troubleshoot to ensure a good user experience. I’m really looking forward to using the paid version to enhance my fasting. Being an avid follower of Peter Attia for many years, his association with this APP meant it was my first choice when needing an IT fasting tool. The APP is there to lean on too when in the middle of a fast the going gets tough.

Developer Response ,

Hi there – We're sorry to hear about this issue with the Black Friday/Cyber Monday event. I see our team has been assisting with troubleshooting the issue in ticket # 26971 and you were able to access the Black Friday/Cyber Monday page in the app. The team will continue to follow up with you through resolution thanks for your patience and understanding. ~Team Zero

Fantastic tool

The new update took a few minutes to get use to but easily grew on me. It is more pleasant to look at and easy to browse thru. The badges section is a welcome change and serves as additional encouragement for users. The weight goal, though has no bearing on me, also will serve as an encouragement for first time users. I would like see more articles and videos in the learn section. What’s already there, I think, appeals to people with no science background; easy to understand and well explained without having to google every sciency scientific word in the articles. Thank you, Zero Team. Fantastic tool and fantastic work!

My Fasting Record

Hi I’ve been fasting only for a short time so trying 16/8 hours but thinking I will extend the fasting time very soon. Love this app as I can see everything very quickly and I understand exactly where I am and how I am succeeding to reach my goals. Am in Ketosis according to my strips and feeling great! Monday morning is weigh in time so I just know I’m going to be down....even just a small amount is special for me. Lost 8kg so far maybe 5kg to go. Subject to how I feel and look. I’m relaxed and enjoying my adventure, first time I’ve been so relaxed while loosing weight! This is an add on, as for some reason the original didn’t get sent! I’m only having one problem and that is my iPad and my iPhone are not working in tandem with this app. I’m a 75y young person but I need help to get my full potential and 100% use of the app. I’m finding it a nuisance to have to go from each place to update and use my zero app and it’s so upsetting! I’m hopeful that someone will be reading this report and then let me know how to fix it!
