Works on old iPhone 11, not on any newer iPhone. ### 1/5 — Doesn’t work *2025-12-18* Ever since the update, none of our iPhones will work with the app. However, Our android users work ### 1/5 — Last update killed it for IOS *2025-11-25* Hasn’t worked since they updated it to the atrocious new design. ### 3/5 — Almost there *2023-01-09* It’s great having many of the fire alarm system controls at your fingertips, but we found that it times out too quickly making you enter your login credentials again after about 1 minute of inactivity. That is not conducive when testing our alarm systems. Javier ### 2/5 — Doesn’t work with notifiers pullstation *2021-01-13* I would like it to have a feature that it could work with notifier fire alarm pull stations but other than that it pretty good so I’m only giving it 2 stars so yea ### 3/5 — Good but needs improvements. *2020-10-16* Not able to notify you about events without having app open. This option can be solved with email per point. But, PLEASE make it customizable to where I can have troubles sent by email. And active alarms sent as an immediate notification to phone even if app is not in use. ### 3/5 — TSW *2020-03-05* Make it be able to send notifications to our phone when there is a trouble, fire alarm ect. ## Frequently asked questions about TSW Mobile Client ### What is TSW Mobile Client?
