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.

Some calls ask too much of a familiar voice, especially when someone wants you to send money, share access, or change plans. You both take part. Pair your phones once, in person. Later, on a call, each phone shows two words to read and two words to listen for. The words change every minute. Read yours. Listen for theirs. Nothing to invent or remember. The words change automatically. USE IT WHEN IT MATTERS: - Before sending money or changing payment details - Before changing plans because of an urgent request - Before sharing access to a home, account, or private information - Any time a familiar voice alone does not feel like enough HOW IT WORKS: 1. Create your identity card on your phone. 2. Add a contact in person using QR code or NFC tap. 3. At the start of a call that matters, open that contact in HiSign. 4. Read yours. Listen for theirs. Your contact does the same. PRIVACY AND SECURITY: - Your profile and contacts stay encrypted on your phone - Your device lock protects the app - No HiSign account and no HiSign-operated identity, contact, or directory server - No analytics, tracking, advertising identifiers, or crash reporting - Network use is limited to clock-health checks and App Store purchase handling - Encrypted, password-protected backups are available when you choose to make one HiSign supports up to 50 contacts. HiSign Supporter is an optional one-time purchase for supporter recognition and a cosmetic app-icon choice. It does not change the contact limit, exchange capabilities, or security model. Built by Insight Velocity LLC. Patent pending.

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.
