### 5/5 — Location settings

*2026-06-16*

Allow app to work with location settings set to While using the app. Currently it only works with location settings set to Always on and it checks ALWAYS.

### 2/5 — Terrible

*2026-05-24*

One of the worst apps I’ve had the displeasure of using. It’s awesome, when it works. Unfortunately, the app constantly bugs you about having your location on at all times for pointless features that drain battery life like crazy. Also have had issues with giving access to non-admin accounts, very buggy. Overall, a good idea with some serious work needed on basic features and user experience.

### 1/5 — Very heavy Handed

*2025-06-12, version 1.1.15*

Requires access to location data always, bluetooth and health data.

### 5/5 — Great App!

*2025-06-03, version 1.1.15*

### 5/5 — Intuition and easy to use!

*2025-06-03*

Pretty easy to use as an employee of a company that uses Rhombus

### 5/5 — Innovative and great support

*2025-06-02*

This app does some really cool things, like wave to unlock. And the support and developer responsiveness is top notch.

### 5/5 — Feels like Magic 🪄

*2025-05-29*

I’ve been using this app for almost 2 years. Once set up properly you almost never have to take your phone out of your pocket! Super easy to gain entry, just wave your hand and you’re in!

### 5/5 — Works Excellent

*2025-05-27*

I highly recommend buying Rhombus access control and cameras. It works flawlessly and really modernizes the experience from an old reader and badge I never remember to bring with me.

### 5/5 — Rhombus key

*2025-05-23*

Easy to use. I like the wave to unlock feature.

### 5/5 — Easy to use

*2025-05-22*

Ok when this app first came out it wasn’t perfect but in the last few months this thing has been great! Makes it easy to let my crew in and out and track their daily usage of our remote office.
