Concierge Go is the ultimate meeting room booking app for iPhone. Concierge Go is the groundbreaking room booking app that enables you to easily find and book an available meeting room with the right facilities and equipment. Booking a meeting room is just a click away, and the app will automatically show the meeting rooms closest to you. Room information, such as location, number of seats and available equipment are clearly stated and it will make it easier for you to find the right room. If equipment in the room is out of order, you can even report it as broken, for everyone to see. Broken equipment are reported to your service desk or another department responsible for solving the issue. The Concierge Go app can work as a stand-alone solution or it can integrate with your Microsoft Exchange, meaning that all bookings made from your Microsoft Outlook calendar will be visible in the app (and vice versa). To prevent ghost meetings you can check-in to existing bookings made from your Microsoft Outlook calendar. Extending or releasing ongoing bookings is of course also possible. Notifications are handled smart. On your phone and smartwatch you will receive a notification when a check-in to a booking is needed or when your ongoing booking is about to end. You can even check-in, extend or end your booking directly from the notification. Concierge Go requires a Concierge Booking Software Account.

Verdict

The call

The clearest difference is rating: Mattermost at 4.8 against Concierge Go's 1.0. Mattermost also leads on ratings volume (5.6K vs 1) and update cadence (every 8 days vs every 3 weeks). Concierge Go's advantage is review sentiment (50% vs 38%) and iOS requirement (14.2 vs 16.0). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Mattermost holds the better App Store score, 4.8 against 1.0. That said, the two scores are not equally well evidenced: Mattermost has 5.6K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 38% of Mattermost's written reviews are positive against 50% of Concierge Go's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Mattermost ships an update every 8 days, Concierge Go every 3 weeks. The most recent releases landed on September 22, 2026 and June 1, 2026 respectively.
