Hi, I'm Zilla.  Besides being an adorable monster, I help you make sense of your wearables data, give you daily recommendations, and help you build Healthy Habits. For free! WHAT USERS ARE SAYING ABOUT US "Superb app for getting more out of my wearables. Now I can monitor and analyze all the data stored in HealthKit from various sources and manufacturers!" "This is a great app. It not only allows you to measure HRV (Heart Rate Variability), it also gives you feedback on your scores. Also, you don’t need to get a heart rate monitor to be able to use it, as it uses the camera on your phone." HEALTHY HABITS We automatically sync your devices incl. Apple Watch, Fitbit, and Oura Ring and other apps to identify your existing Healthy Habits. Everything from getting 10,000 steps and 7 hours of sleep to intermittent fasting and different kinds of workouts. We score each Habit based on frequency, with daily being the highest level. There's 16 Healthy Habits now and we keep adding more! CHOOSE YOUR GOAL You can choose from 6 different goals, that will drive our recommendations and challenges for your Habits through the app: Longevity, Weight Loss, Strength, Lower Stress, and Activity. FREE ACTIVITIES To support your Habits, and help you start new ones, we also provide free programs for many Habits. There's a 2-minute breathing exercise when you need a break, and a meditation timer for when you need to de-stress. You can use the fasting timer to fit your 16:8 intermittent fast into your daily schedule. LEVEL UP! Since we can read your health data in the background, you don't even have to open the app. We'll tell you when you hit new Levels or introduce new Healthy Habits! 100-DAY CHALLENGE New year, new you? Look no further. Take our 100-Day Challenge to build your Habits to put your Goal into high gear! Every week, we will add to your Habits to keep you on the up & up. DAILY STRESS SCORE Check in every day to see an instant analysis of your stress and recovery levels! The more data you capture, the more accurate the result. We produce a simple understandable score by analyzing trends in your wellness data to find patterns indicating a good or bad stress response, using data including Resting Heart Rate ("RHR"), Heart Rate Variability ("HRV), Sleep hours, and Workout minutes. STRESS SCAN, NO WEARABLE NEEDED Healthzilla can now read your resting heart-rate and variability using your phone's camera, for your daily stress score! It takes just 60 seconds, and will give you the full stress score analysis as with a wearable device. Do it every morning before getting out of bed for best results. DAILY RECOMMENDATIONS Zilla analyzes your workouts stored from fitness apps or wearable devices (Apple Watch, Fitbit, Oura Ring), and recommends what activities are the best today given your Stress Score. Is today a great day for a Strava bike ride, or an intense 7-minute workout? Maybe best to just go for a walk. APPLE WATCH SUPPORT The Apple Watch provides the best data for Healthzilla. We can automatically read your resting heart rate and heart rate variability to deliver your Stress Score in the morning. All your activity and workouts contribute towards your Habits. FITBIT SUPPORT We now also support connecting to your Fitbit account incl. steps, resting heart rate, sleep, weight, workouts, and food calories. OURA RING SUPPORT Sync all your data directly from your Oura Ring to power the daily stress score and habits incl. resting heart rate, sleep, steps, and heart rate variability. HEALTHKIT SUPPORT Healthzilla can sync any devices and apps that support HealthKit, to store the data to be shared in the Apple Health app. Devices include Wahoo, Xiaomi, Nokia, and Garmin. This includes popular apps like Lark, Lifesum, MyFitnessPal, Strava, Nike, Calm, Oak, Headspace, Cardiogram, 8fit, Zova, and Waking Up. We read up to 15 data points and 16 Habits automatically.

It blanks out when I try to add data. It’s too bad because it is what ai am looking for. ### 1/5 — Glitch *2022-06-04, version 3.1.8* Every time I go to open the app and create an account the page goes blank and i can’t continue. ### 1/5 — keeps on loading *2021-10-28, version 3.1.7* downloaded this app today. after when i registered, it keeps on loading forever! please fix this. ### 2/5 — Not available for Apple Watch *2021-04-05, version 3.1.6* I’ve downloaded this app for me to use it as my stress checker; and I read that it applicable for Apple Watch. Why after I try to sync it with my AW, it didn’t work and only I realized that it’s not compatible for any wrist wearable devices? ### 3/5 — Confused *2021-03-02, version 3.1.6* Isn'this app accurate? ### 1/5 — Doesn’t seem to work with 12Pro Max *2021-01-19, version 3.1.5* The app continually wants me to do the stress test but doesn’t work with 12 Pro Max camera. It says be patient but after two minutes nothing. Following up on my rating. There doesn’t seem to be anywhere in the app to change things previously set. This is frustrating. I was using the IF clock and it asked me if I wanted a reminder. I said yes and hit the wrong time and now it can’t be changed. So now I get reminded to Fast at noon rather than 7pm. It asks me to “stress scan” daily but that doesn’t work with the Pro Max flash/camera configuration it seems. The app could be useful but it’s very rigid and overall frustrating. ### 5/5 — Overall Health *2020-12-09, version 3.1.5* Best app I’ve encountered to provide an overall health vs. just one metric! Easy to use! Easy to understand information! ### 5/5 — A Hidden Gem! *2020-09-30, version 3.1.4* I have been trying a lot of HRV apps since I swapped to Apple Watch. For whatever reason, this didn’t show up in my search until only a week or two ago. Good job it did because it’s doing a fantastic job! It’s very simple, giving you a score in your recovery and then suggests things for you to do that day. If you are doing well for example, it suggests you go do some strength or cardio, if not it might tell you to rest or do some mobility. It takes into account your baseline averages over certain periods of time, so it doesn’t just give you an arbitrary score that changes drastically because your Apple Watch took one HRV reading that differed wildly from the rest. So far the recommendations have been pretty consistent with my Polar Watch. I am hoping it keeps being this way because then I can ditch the Polar and just have one watch. It also has a habit based approach to changing your lifestyle for the better, which is the healthier way of doing it, rather than a short term restriction regime. So it will encourage you to form a habit to exercise, or form a habit to sleep better, etc. Definitely recommended both for its simplicity and its accuracy. ### 4/5 — SURPRISED 🌠🌠🌠🌠🌠 *2020-09-24, version 3.1.4* HEALTHZILLA is definitely a concept ! I simply LOVE the essential design as well as the functionality. The data contents are quite complete and well targeted. NEVERTHELESS... that monster is quite a chipie! I am not even sure he likes the human race... he is probably not the only one, true. Ok so I am just wondering why I keep getting a « sick » diagnostic, whereas I am in super shape and have low heart beat... I will keep on for the next few days, see how it moves on :) Thank you team Godzilla 🙏😁 ### 5/5 — Works smoothly *2020-07-14, version 3.1.2* It was quite buggy for me when I first downloaded it, but updates fixed everything. It works great and pulls data directly from the Apple Health app. It’s intuitive in an adorable monster kind of way. Zilla encourages you to push it when your data looks strong, and cautions you when to take it easy. ## Frequently asked questions about Healthzilla ### What devices does Healthzilla sync with?
