As well as this it adds steps from earlier in the day to the total for the day so some are imported twice. Have managed to prioritise the Fitbit steps in health over the phone pedometer but really annoying having to delete 2 lots of step imports every day as I want the final step count to be accurate. ### 1/5 — Doesn’t work at all *2020-02-14, version 1.1* Won’t sync with Fitbit. Doesn’t work at all ### 1/5 — Was syncing and then quit *2020-01-07, version 1.1* The data was syncing fine and then stopped altogether a month ago ### 1/5 — No heart rate *2020-01-06, version 1.1* Despite what it shows in the images it does not sync heart rate data, and so is useless. ### 1/5 — Heart rate doesn’t sync. Steps not accurate *2019-12-27, version 1.1* Heart rate data is completely inaccurate because instead of using specific data points, the app using your daily average as the input value into Apple health. Resting Heart Rate values are ignored by this app. Additionally, the step counts from your fibit are ADDED to the step counts that are automatically tallied by your phone, thus the value you see in the Health app will never be accurate. There is no way to select which data source to use for steps, so you just have to tolerate having incorrect numbers. While is don’t entirely fault the app for some of the issues, it still doesn’t take away the fact this it is entirely worthless as a mechanism of moving your Fitbit data into the health app. ### 3/5 — Syncs good *2019-08-11, version 1.1* Syncs great just a little too often ### 1/5 — Doesn’t work *2019-07-22, version 1.1* Fails to sync every time, even when data is being accessed. ### 3/5 — Not syncing heart rate *2019-07-02, version 1.1* The picture shows that it syncs heart rate for Fitbit and that’s the only reason I bought it, but it syncs everything but heart rate ### 4/5 — Behind *2019-03-01, version 1.1* The app is excellent! But there is one problem! The app with sync to the health app but it doesn’t sync all of my steps! Like recently I had 900 steps on my Fitbit, but when it synced it put 100 steps on the health app! Am I doing something wrong? Please fix this issue! ## Most critical reviews (10 lowest-rated) ### 1/5 — App buggy *2025-12-24, version 1.1* App constantly crashes ### 1/5 — Doesn't work *2025-09-24, version 1.1* I purchased this for $1.99 and I cannot get it to stay open long enough to sign-up or sync anything. ### 1/5 — No Longer... *2025-09-11, version 1.1* Auto Sync for Fitbit to Health by Sunny Studio used to be absolutely perfect! It was quick, completely free, and with absolutely no ads or intrusive links. Then, one day mid 2025, it just STOPPED WORKING! I restarted my phone, closed, reopened, changed WiFi, uninstalled and reinstalled. But nope, now whenever you click to "sync steps", the app automatically CRASHES. Every time. Even worse, the message I sent to the "support email" I found has never replied. Huge shame... (But, at least thank heavens that yes, there is a very similar alternative: FITIV. Free, no ads, and they actually do respond to App Store posts, so they are definitely "active"!) ### 1/5 — Funktioniert nicht *2023-07-14* Die App wird von  Healt überhaupt nicht erkannt also Nutzlos. Geldverschwendung. ### 1/5 — Doesn’t work correctly *2023-05-19, version 1.1* This doesn’t work correctly, always gives out wrong information. Don’t use. Should get money back for false advertising. Scamming app beware ### 1/5 — Sleep data not included! *2022-02-09, version 1.1* Does not synchronize sleep data even though it says in the description that it does! ### 1/5 — Not perfect *2022-02-05, version 1.1* It says it is syncing. Got it because I walk a lot and my iPhone apps don’t have access to my Fitbit If I walk 14k steps it logs about 1/2 that to my iPhone health Doesn’t work for the shoppers drug mart app or sweatcoin :/ ### 1/5 — Doesn’t work *2021-01-12, version 1.1* Sent an email with the error log and never got a response. Tried to look for settings that may cause the errors but no settings exits. Just a waste of money. ### 1/5 — Doesn’t sync heart rate *2020-10-23, version 1.1* The app images look like it should sync heart rate but it doesn’t show up as an option on Health when you go in to turn categories on or off. ### 1/5 — Doesn’t auto sync *2020-07-12, version 1.1* You have to open the app and click sync now to sync. I thought it would automatically sync in the background once a day at 12. Disappointed that it doesn’t do that. ## Most praised reviews (10 highest-rated) ### 5/5 — Does what it says *2025-03-02, version 1.1* Syncs the metrics that I was interested in to my iPhone health and fitness app. Some manual input involved but still what I needed for my minimal inspire 3(Workouts, movement circle) calories, steps. It’s not perfect but I’m not trying to be exact just something to measure in the ballpark to stay motivated and moving. ### 5/5 — Works as said *2021-01-06, version 1.1* Too bad Fit bit and Apple can’t come to a deal where you don’t have to download a third party app like this. It works as they say. ### 5/5 — Not Working For Me *2020-09-16, version 1.1* I took out a subscription to auto sync so that I could get steps registered in Fitbit to Auto Sync with another app called Achievement. I have yet to get it to auto sync once. The only way I can get the steps to sync is to manually do it. And then it will only give me some of the steps, not all the ones registered on my Fitbit. It’s not working for me. ### 5/5 — App rocks!!! *2019-02-17, version 1.1* This app is going to change my life!!! ### 5/5 — So far so good *2019-02-17, version 1.1* Works as expected, syncs all my Fitbit data over to the I-health app. ### 5/5 — It does everything it promises *2019-02-17, version 1.1* Fitbit provides very helpful data in a timely manner. I am very pleased. ### 5/5 — Great. Easy. *2019-02-17, version 1.1* Exactly what I was hoping for.. ### 5/5 — So happy! *2019-02-16, version 1.1* I'm so happy there's an app the moves my Apple Health data to my Fitbit app. ### 5/5 — Does what it promises *2019-02-16, version 1.1* I only use one app to view all my fitness and health data. ### 5/5 — So grateful *2019-02-16, version 1.1* Great way to combine both Apple Health and my FitBit --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
