### 2/5 — バックグラウンド同期できない

*2023-04-25*

バックグラウンドでの同期を期待して購入したが、設定を有効にしようとすると現在テスト中のメッセージが表示され無効化される。

### 3/5 — 【訂正あり】ログインできない

*2021-03-28*

アプリ内ブラウザでログイン画面が表示されない。ログインできないから同期もできない。返金して欲しい。

2021/03/28 追記
一晩待ってもう一度試したらあっさりログイン画面が出てきた。不思議。
星1→星3に変更。

### 2/5 — Inreliable syncing.

*2020-06-03, version 2.0*

Not al data is synchronized and when the internal step counter of the phone is activated along my fitbit, steps are counted double...
Not happy with this app

### 2/5 — Still no background sync

*2019-12-31*

Background sync has been “in development” for over 3 years now, I paid for that feature so release it already!!!!

### 2/5 — 残念

*2019-11-07*

課金した途端同期できなくなった

### 1/5 — Does not sync the past

*2019-08-22, version 2.0*

App will only sync today and no last data making it useless.

### 2/5 — It works but....

*2019-06-27*

So this app technically works.  It transfers info from your FitBit to the iPhone HealthKit.  The paid version claims to NOT allow duplicate data but I have found that is not the case.  For example, so far today I have taken 4285 steps. The HealthKit shows 8570 steps.  It also has inaccurate figures. I have told FitBit I had 48 oz. of water today.  The HealthKit shows 1420 oz. of water.  Where does that info come from?  No one knows.  There are other issues but you get the idea.

### 1/5 — Heart rate not showing

*2019-06-10, version 2.0*

I bought this app because it looked like one of the very few to sync heart rate values as well as all the rest.

Sadly my heart rate never syncs with Apple healt!

### 1/5 — Not support Auto sync!

*2019-05-11*

有料版買ったのに、自動連携ボタン押したら「まだ検証中で使えません」だと。そのうち対応するよ、だそうです。対応してから有料にすべきじゃないかい？？？

### 1/5 — Doesn’t work

*2019-04-05*

None of my information is syncing even after spending the $5 or whatever to upgrade to pro. The only thing that synced to Apple Health was like 9 steps from 3 in the morning one night and 3 calories. It was so random. I really want my money back.

### 1/5 — Bought with the Fitbit finder

*2019-03-24*

Neither works, but great sales pitch.

### 2/5 — Where’s the Background refresh?

*2019-02-25*

Well over a year......still doesn’t function.

### 3/5 — Still waiting for auto sync

*2019-02-20*

My favorite Fitbit sync app but it’s not automatic yet! It’s been over a year!

### 1/5 — Not working

*2019-02-05, version 2.0*

Sync button on iPhone SE is hidden. No reply from developer.

### 1/5 — Doesn’t work

*2019-02-04*

Doesn’t sync properly with health

**Developer response:** Hi,
Can you email us at support@deucks.com
We want to know what exactly doesn't sync to health.

### 2/5 — Inaccurate data transfer

*2019-02-04*

Weight synched only 2 digits

**Developer response:** Hi,
Can you please elaborate on this issue. Send us an email at support@deucks.com 
We will fix it right away.

Thanks,
Deucks Team

### 1/5 — Health sync doesn’t work

*2025-09-19, version 2.0*

For 1 day the sync works, but after that I have to disconnect my Fitbit and connect over and over again for the sync to work. Not use friendly.

### 1/5 — Just Don’t

*2022-09-26*

Dude says the app will do all sorts, but it really doesn’t. Steals your money and then doesn’t respond to any support requests. 

How do you sleep at night???

### 1/5 — Not working

*2022-01-13*

Have tried a few days. Not sure if Apple Health is the issue or this App but it is not syncing the Fitbit data to Health. Steps are all over the place.

### 1/5 — Not good

*2021-10-19*

It doesn’t sync in the background, but it’s advertised. It freezes, I have close and open many times. If I remove the lite version, the pro is not working. Waste of money.

### 1/5 — Stopped working

*2021-03-28*

Unable to login to Fitbit. Waste of money

### 1/5 — Sync in background announced but not delivered

*2020-05-20, version 2.0*

Waste money they sell the background sync but is not present

### 1/5 — Can’t log into fit bit

*2020-03-16*

I paid for this and I’m not able to log into my Fitbit no matter what I try using to sign in, it shows a blank screen after sign in. Nothing loads in. Why did I buy this app. This app sucks

### 1/5 — Non funziona

*2020-01-30, version 2.0*

Semplicemente... non funziona.
Soldi buttati. Assurdo!

### 1/5 — Stopped working on my X

*2019-10-29*

It stopped working on my iPhone X but still works on my iPhone 8 and my 7th gen iPod. I paid for this???

### 1/5 — Sync of weight

*2019-10-11*

The Sync does not work for weight.  In the years I have used the Apt, the weight has always transferred correctly from the digital scale to the iPhone.  The Sync then never transfers the correct weight to the “Health” Apt for my record and tracking.  How do I fix the problem?

### 5/5 — Great little app

*2020-05-28*

I found this app perfect for me to fully update my iPhone health app. 
It was quick and easy to use and did the job I wanted without any problems

### 5/5 — Fitbit three

*2019-03-27*

when I am wearing my Fitbit, it gives me incentive to walk more, and to exercise more. Thanks, Fitbit, you are fabulous!

### 5/5 — Great

*2017-06-24*

Only app I can get to sync into my Fitbit app

I bought 5 and this is only one that works

### 5/5 — The Missing Link

*2017-05-15*

I am frustrated with Fitbit not by default integrating with HealthKit. But like another review said, I bought the deluxe version to help support the development of the App.

### 5/5 — It works!

*2017-04-12*

I paid for the deluxe version to reward this company for working around Fitbit's ridiculous aversion to making their products sync with Apple Health :) This app cannot yet sync Fitbit to Health in the background, which would be ideal, but it's an easy app to use and will prompt you to sync before the end of the day.

### 5/5 — Great Health Enhancer

*2017-04-02*

Fit Bit is a user friendly device with so many health promoting programs & features!A smart Heath monitoring program which has so many integrative measurements & activities!! Definitely a very valuable system with so many desirable activities. It is fun enjoy!

### 4/5 — Ok so far

*2019-07-09, version 2.0*

Ok so far with one issue. It syncs my nutrition from Fitbit to Health, but when I delete a food item from Fitbit and try to update/sync it on Health, nothing happens. I will try to re-sync at a later time to see if it updates or not.

### 4/5 — New version

*2019-02-09*

This is a nice update but the app is still crashing near the end of the sync session. This is a bug from the previous version that still exists.

**Developer response:** Hi, do you know at what stage the app crashes at, like if it was at sleep or steps. Email us at support@deucks.com and we will figure it out

Thanks

### 4/5 — Funziona

*2018-08-06, version 1.1*

Funziona! Sincronizza i dati da Fitbit a Salute, peccato non possa ancora farlo automaticamente.

### 4/5 — Best Fitbit sync

*2017-07-13*

I've tried a few of these sync apps now (even the pro) versions and this has proven to be the best and most reliable so far. Even gets the sync times right as opposed to sync solver for example.
