GEM Client
Read full descriptionHide full description
GEM Client is an all-in-one mobile client that includes Alert, Panic, and Check-In features that work in conjunction with Genasys' critical and emergency communication platform: GEM Enterprise, an emergency communications solution that is purchased by an organization to protect its employees, contractors, and visitors. The app functions only when you register with at least one organization using the GEM Enterprise solution that you wish to be associated with. The organization will inform you how to register. The Alert functionality provides rapid reception of multimedia emergency communications from the organization(s) security team(s), based on your location (subject to your approval to share location) and/or group membership. Upon receiving an alert, the app will attempt to vibrate your device and pop-up a full-screen view of the alert content. It can also optionally play an audible alert tone and read the message, subject to settings that you control. The organization may include a list of responses in the alert that you can activate to acknowledge reception. The Panic functionality allows you to provide instant status information to an organization's security team, using either a single button activation or selection from a list. At each activation your location is shared with the organization (subject to your approval). Panic can be enabled for only one organization at a time (usually your employer or a local authority). The Check-In functionality is used to provide periodic answers to questions to an organization's security team, such as a periodic lone-worker or remote check-in, or for health checks. Check-In can be enabled for only one organization at a time, and the organization has the ability to add or remove you from different check-in profiles at any time. The app will remind you when to check-in, and the organization may also send alerts to remind you to Check-In.

A familiar voice can be imitated. The HiSign app lets two people who have already connected check a voice conversation together. Each person speaks a fresh two-word phrase and checks the other personβs words against their screen. The phrases change every minute and come from private information exchanged when they connected. Speak your phrase and hear theirs. The family safe-word, upgraded! FOR YOUR PEOPLE Make a phrase check a shared habit with family, friends and colleagues you have already added in person. Practice together before an important call. FOR YOUR TEAM Start with one colleague and practice both sides. Agree when to check a call, including a change of plan or a sensitive request. Each contact relationship has its own phrase pair; the team does not share one group phrase. FOR IMPORTANT BUSINESS CALLS Use a mutual phrase check with established colleagues and clients who have paired in person. Your team checks, and clients can check back. CHECK TOGETHER 1. Create your HiSign card and add each other in person using QR codes or NFC. 2. On a call, open your contact's Quick Phrase screen. 3. Read the words under "You say". Compare the words they read back with the other phrase on your screen. 4. Your contact does the same. Both sides take part. EASY TO REACH, EASY TO READ - Choose compact Rows or comfortable Tiles for your Home screen. - Recognize your contacts with colored shields, names and optional aliases. - Read both sides of the phrase pair in a clear Quick Phrase view. - Keep key contacts close with Home Screen widgets. - Use password-protected encrypted backups when moving to a new phone. ON YOUR DEVICE Your stored profile and contact data are encrypted on your device. HiSign requires device-owner authentication to unlock (Face ID, Touch ID, or device passcode). There is no HiSign account or HiSign-operated identity or contact server. Contact exchanges and encrypted backup transfers happen when you initiate them. Clock-health checks and App Store purchases use network services. HiSignβ’ is a trademark of Insight Velocity LLC.

Verdict
The clearest difference is in-app purchases: GEM Client at none against HiSign's 1. GEM Client also leads on device support (4 vs 1) and iOS requirement (9.0 vs 16.0). On price, update cadence and ads there is nothing between them.
