## What is JustIN Mobile?

Salto JustIN Mobile access technology simplifies the users and dynamic key management process of users in a building. Receiving a key generated electronically on their smartphone, previously identified and authorized by the system, they can unlock the assigned doors from the JustIN Mobile app by selecting the appropriate key.

Technologically cutting-edge, JustIN Mobile means the end of lost key hassles, expenses and waste. Plus, the technology isn't limited to one building or hotel room - it can also be used by staff and users on multiple sites for any kind of access types like main entrance doors, elevators, car park barriers, meeting rooms, etc.

Combined with user-convenient features such as user friendly design or multi key possibilities to use the same app in different buildings, locations and for different applications, JustIN Mobile access control technology simplifies card issuing, fob and traditional PIN code management that can be lost, forgotten or broken by offering flexibility for diverse applications. People do not forget their phones as they forget their keys and, if lost, they are replaced rapidly. This is a major benefit for administrators, clients, and users.

### 3/5 — Add cards to Apple wallet

*2026-07-29, version 3.0.7*

I like the app it works great. I just wish I could just tap to open instead of opening the app and logging in and then wait for the locks to open. If the app had an apple wallet extension I think it would be better

### 1/5 — Kills battery

*2026-07-15, version 3.0.7*

The app prevents the screen from locking so it just kills your battery. There is 0 reason for it to prevent screen lock, unless they do it to invade your privacy and track you.

### 5/5 — 👍

*2026-07-09, version 3.0.6*

👍

### 5/5 — Convenient Key Companion!

*2026-06-29, version 3.0.6*

This system makes it so easy to carry your key to your apartment and you never seem to forget it because most of us have our phones on us all the time!

### 5/5 — Super convenient!!

*2026-06-18, version 3.0.6*

So easy when we return to our campground. We don’t have to wait while other campers check in. Works smoothly each time. Love it!

### 5/5 — Salto nouveau

*2026-06-16, version 3.0.6*

Good

### 5/5 — Great app

*2026-06-15, version 3.0.6*

Easy and fast

### 1/5 — Issue

*2026-06-11, version 3.0.5*

It takes too long to activate. Must have a feature to add key in Apple Pay wallet

### 1/5 — Barely works

*2026-06-01, version 3.0.5*

30% chance it’ll work on the first try. Incredibly annoying when you’re standing there for minutes trying to lock a door

### 1/5 — Terrible overall

*2026-05-28, version 3.0.5*

Somehow you manage to make the app worse and more unreliable since the last update. I’m need to scan my key in average 3 times for it to work and sometimes it just doesn’t work and I have to call security to let me in my own apartment.
