### 5/5 — MaX UC

*2026-06-03, version V3.21.63*

It is a very nice solution in-shorts distances and solves problems wherever you need a calling/contacting platform to connect with people

### 3/5 — Great, when it works properly

*2025-11-20, version V3.21.60*

I work for a company that uses MaxUC for our business phone service and for the most part if works quite well. Being that we provide the product internally I can easily get assistance, however, ever since iOS 26 this app has been absolutely awful. While audio remains fine, if music is playing and I dial out, the music will start again while making call; this doesn’t occur on inbound calls. In addition, lately speaker shuts off automatically for no apparent reason. If the dialogue box is open and I keep it up the speaker will stay on. If speaker is launched from a locked phone when call comes in there are no issues unless phone needs to be unlocked. 
Another issue is related to the speaker issue that then causes the mic recording light to stay on, or the mic in the Dynamic Island. 
If these particular issues could be resolved app could go back to 5 stars but at current it is quite atrocious.

### 4/5 — Great app but no text

*2025-11-06, version V3.21.60*

I love the app for the call and what it does. I just wish you could text from it as well.

### 1/5 — Non funziona nulla

*2025-03-21, version V3.21.24*

La linea cade costantemente, si perdono le credenziali di accesso se si spegne lo smartphone per un giorno, spesso non funziona il servizio.

### 2/5 — Crashing since latest update iOS

*2024-12-13, version V3.21.23*

Cannot open it since the latest iOS update

### 1/5 — iPhone 15

*2024-12-10, version V3.21.23*

With iOS 18 the app keeps crashing even after recent update !!!! Please fix!!! Dec 10 and still doesn’t work after latest updates….

### 1/5 — voice muffled

*2024-12-05, version V3.21.23*

When I use the default Phone app with my airpods, my voice sounds perfectly clear.

However, using my airpods with this app makes my voice super muffled!! Very frustrating.

### 1/5 — Dead Since iOS18

*2024-11-29, version V3.21.22*

App crashes upon launch after logging in the first time. iPhone 16 Pro with iOS18

### 4/5 — Great but needs shortcuts or preferences

*2024-09-04, version 3.21.17*

Love the ability to answer calls from anywhere.   Wish there was a why to set preferences so you don’t have to press 4 buttons to transfer a call.

### 4/5 — Microphone stays active

*2024-08-20, version 3.21.17*

Tends to leave your microphone active.  I notice constantly on the latest iOS that even after a call finishes the microphone is still active until I force the app closed.  Users should beware that it may be listening to you and those around you.  Pay attention to the Mic icon at the top of your phone.
