Flexibility of service configuration and ease of use API for custom scripts. > > **Cons**: Sometimes it signales to fast if we forgot to disable the monitoring for maintenance ;-) > > It is easy to use and never have any disadvantages or service issues during the whole lifetime ----- ### "SIGNL4: Highly recommended\!" — 5.0/5 > **Georg** | *5 March 2021* | Telecommunications | Recommendation rating: 10.0/10 > > **Pros**: Very well designed and very reliable. Very flexible. A very wide range of integrations and implementations are possible. Excellent Ui and UX. Excellent support\! > > **Cons**: We could not identify any cons and neither experienced any problems. > > We are in the active in the wide area of security solutions and SIGNL4 is the perfect extension for our applications\! ----- ### "Signl4" — 4.0/5 > **Cherie** | *23 September 2020* | Utilities | Recommendation rating: 10.0/10 > > **Pros**: Was the only app available that worked well with IPhone. All other apps were designed for Microsoft products > > **Cons**: At first you had to confirm and resolve each alarm one by one. That has been changed, works great now. > > Easy to use and does what it needs to do. ----- ### "The App we've been searching for\!" — 5.0/5 > **Fr. Paul** | *3 January 2020* | Religious Institutions | Recommendation rating: 10.0/10 > > **Pros**: I have been looking for an app like this for over 2 years\! Finally, an emergency alert app that gives persistent notifications, and can work with iOS to even alert you when you have Do Not Disturb enabled. Since this app allows a variety of choices for the persistent alert, including a phone call from a consistent phone number, I can set the SIGNL4 phone number as a favorite in my contacts, and then my alert comes through even if I set the phone to DND (and allow favorites in the DND settings). This allows me to sleep without interruption unless there is a true emergency\! This app does so much more also, scheduling team members, making sure someone is always on duty, and even making provision for unanswered alerts to be escalated to a manager after a set time frame. We use it at our Church for an emergency. What I really love is that a parishioner calls in to our church phone system and leaves a voicemail in our emergency voicemail box, then my phone emails the voicemail to SIGNL4 app and after the alert, there is the voicemail accessible by a PLAY button within the app\! Thank you SIGNL4, you have thought of everything\! > > **Cons**: Have not found anything yet that we do not like... Seems like they've thought of everything. > > Using for emergency calls in a church. Team members love it. I love it. ----- ### "Absolutely reliable\!" — 5.0/5 > **Frank** | *7 September 2020* | Transportation/Trucking/Railroad | Recommendation rating: 10.0/10 > > **Pros**: The high reliability of the software is unique\! We searched for a comparable solution for a long time\! The solution is very easy to implement and use\! Suggestions for improvement are implemented quickly\! > > **Cons**: I think everything ist perfect for us\! On this time i would not change something\! > > We wanted to replace the alarm with our old city call devices. This was no longer up-to-date and the reliability was not always given. With Signl4 we no longer have to hand over hotline cell phones and city call devices. The active hotliner is automatically put into service. The planning of the hotliner has become much easier. Thanks to the hotline overview, it is also more manageable. ----- Page: 1 / 2\ Next: [Next page](https://www.getapp.ie/software/2048219/signl4?page=2) ## Links - [View on GetApp](https://www.getapp.ie/software/2048219/signl4) ## This page is available in the following languages | Locale | URL | | de | | | de-AT | | | en | | | en-AE | | | en-AU | | | en-CA | | | en-GB | | | en-IE | | | en-NZ | | | en-SG | | | en-ZA | | | fr | | | fr-BE | | | fr-CA | | | nl | | | nl-BE | | ----- ## Structured Data
