### 1/5 — The new rewritten version no longer works

*2026-03-25, version 12.2*

I bought the Pro version a long time ago. This new version no longer works at all - click on the Google button to sync and nothing happens! Also the new app refused to recognise that I had paid for it, and just filled the screen with ads. I had to delete the app and reinstall for it to recognise my purchase. I would give it zero stars but can’t.

### 1/5 — Quiero comprar la versión pro y no deja pagar

*2026-02-06, version 11.4*

No deja pagar ni comprar la versión pro

### 1/5 — Yahoo fehlt

*2025-02-11, version 11.4*

### 1/5 — $120專業版，要簡單備份聯絡人功能還要再要求$90購買才能用，

*2025-01-07, version 11.4*

不知道花了$120專業版的意義爲何？還是會跳廣告干擾，而且簡單的備份聯絡人功能，還要再要求$90購買才能用，一條牛扒好幾層皮，$120專業版費用白花了

### 1/5 — Pague la app y la quiero usar otra vez

*2024-07-26, version 11.3*

### 1/5 — Inutile pagare

*2024-05-08, version 11.2*

Massimo 100 contatti importati poi devi pagare. Poi ho scoperto che puoi importare i contatti da Google gratis dalle impostazioni di iOS quindi l’app é completamente inutile.

### 1/5 — 收費還要看廣告

*2024-02-03, version 11.1*

單次收費150， 還強迫看廣告。 
顯示同步完成，但是我的google 聯絡人3700多筆 並沒有匯入iphone 聯絡人中。
反饋訊息app 還直接登出。

### 1/5 — 환불요청바람니다.아이가 잘못눌렀어요
