Setting Up Your JT5 SE Watch

How do I charge the watch?

Before starting setup, charge your JT5 SE fully. Attach the charging clip to the back of the watch and plug the wall adapter in. The screen will show a charging indicator. A full charge takes approximately 90 minutes.

Setting Up the Cosmo App

App Overview

The Cosmo app is your control center. From here you can view your child's location, manage contacts, set Routines, review messages, configure settings, and manage your account. The app is available on both iOS and Android.

App Navigation

The main navigation gives you access to:

  • Home: Map view with child location
  • Activity: Chronological feed of device and account events
  • Controls: Child Profile/devices, My account, My parent portal, Push notifications, Support, Sign out
  • Child Profile: Routines, Contacts, Guardians, Alarms, App station, Fitness, Location tracking, Preset Messages, Safety features, Location history, Call history, Remove device.

Inviting a Guardian

You can invite additional Guardians who get their own login and access to location, messages, and controls.

  1. In the app, go to your child's profile and tap Guardians.
  2. Tap the + button and enter the guardian's name and email.
  3. The guardian will receive an email from no-reply@cosmotogether.com with an invitation.
  4. The guardian downloads the Cosmo app, creates an account. The invite will pop up during onboarding if the guardian is a new user or if they are a current user it will appear in Controls or their activities in the Cosmo app.

They now have full access to the following:

  • view child on map with the shield icon
  • access the child profile in Controls
  • receive child activities and push notifications
  • can edit child profile, location settings, and safety settings
  • can manage location tracking, contacts, safezones, focus times, and preset messages
  • can view call history and fitness history
Note:

 Guardians share the mostly the same level of access as the primary parent for day-to-day features but cannot change billing settings or remove the primary parent's account.

Adding & Managing Contacts

Contact Types

There are three types of approved contacts on the JT5 SE:

  • Contact: Can call and text the watch. Does not need to accept an invite — once added, they can communicate immediately.
  • Guardian: Can call, text, and see your child's GPS location. Must accept an email invitation to activate access.
  • Buddy:  feature lets two kids add each other as contacts directly from their watches using Bluetooth.

Adding a Contact

  1. In the Cosmo app, go to your child's profile and tap Contacts.
  2. Tap the + button.
  3. Select from contacts, create new or cancel.
  4. Enter the contact's name and phone number.
  5. Select which watches to allow the contact to connect with.
  6. Tap the blue check button to save the contact. 
  7. The contact will appear on the watch immediately.

Adding a Guardian

  1. Follow the same steps above but select Guardian as the contact type.
  2. Enter the guardian's name, and phone number.
  3. The guardian receives an invite email to accept the request.
  4. The guardian downloads the Cosmo app, creates an account, goes to My Devices, and taps Confirm to accept.

Adding a Buddy or Buddy request

The Add a Buddy feature lets two kids add each other as contacts directly from their watches using Bluetooth.

  1. Both watches must be nearby with Bluetooth enabled.
  2. Each child opens the Add a Buddy app (purple icon on the last app page) and finds each other.
  3. Both children tap the checkmark to confirm.
  4. A pending request will appear in each parent's Cosmo app under their child's Contacts and on the Activities page. 
  5. From controls, select the child's name that has a blue indicator next to their photo, select contacts, select review, select approve or reject.
  6. Both parents must tap Approve in the app. Once both approve, the kids can call and text each other.
  7. You can also delete a buddy following the same instructions as deleting a contact.

Removing a Contact

  1. In the Cosmo app, go to your child's Contacts.
  2. Tap the contact you want to remove.
  3. Select Remove Contact. The contact is removed immediately from both the app and the watch.
GPS & Location Tracking

Viewing Your Child's Location

Your child's current location appears as a pin on the home screen map. Tap the pin to start Live tracking. Each location entry is listed in the Location history. That information can be accessed in the child profile page.

Tip:

Turning on WiFi on the watch improves location accuracy when your child is indoors.

Configuring Location Update Frequency

You control how often the watch updates location. The default is every 30 minutes between 7am–7pm (watch's timezone).

  1. In the Cosmo app, tap your child's profile.
  2. Go to Location tracking.
  3. Choose your preferred interval: 5, 10, 15, 30, 45, or 60 minutes — or turn updates off entirely.
  4. You can also choose whether updates run 24 hours a day or only during a custom time window.
  5. Tap the blue check mark to save.

Available intervals: 5 min · 10 min · 15 min · 30 min (default) · 45 min · 60 min · Off

Important:

Important: More frequent location updates use more battery. Setting updates to every 5 minutes will significantly decrease battery life compared to the default 30-minute setting. The JT5 SE is designed for 24+ hours of battery at default settings. If the battery drains faster than expected, reduce your location update frequency or limit the active window to daytime hours.

Live Tracking

Live Tracking activates HaloGPS at full power, updating location every 5–10 seconds for up to 15 minutes.

  1. From the app home screen, tap your child's pin on the map.
  2. Then tap Track.
  3. Location will update every 5–10 seconds until you close the app or 15 minutes pass.
Note:

Live Tracking may drain battery quickly. Use it for short periods when you need real-time reassurance — not as a default setting.

Location History

View a timestamped trail of where the watch has been.

  1. From the app home screen, tap profile.
  2. Tap Location History.
  3. Use the calendar to select a date and view historical location data.
Routines & School-Fi Routine

What Are Routines?

Routines are location- and time-based rules that automatically adjust what the watch can do. Instead of manually turning settings on and off, you set them once and Cosmo handles the rest. The most powerful Routine is School Routine — it automatically puts the watch into a focused, distraction-free mode the moment your child arrives on campus.

Setting Up School -Fi Routine

  1. In the Cosmo app, tap add Routines, then select the school icon when creating your Routine.
  2. Or if you haven’t set a Routine up yet, you’ll see  “Add your first Routine”
  3. Search for your child's school by name. If it doesn't appear, you can type any address manually.
  4. Review or adjust the school schedule (days and hours).
  5. Set your preferred restriction level. 
  • Fully restricted - Child can only activate SOS
  • Partially restricted - Child can only activate SOS, call or message primary parent or guardians. 
  • Unrestricted - Child uses the device as normal.
  • Tap Save. School Routine is now active.

Once active, School Routine will automatically switch the watch into focused mode when your child is on school grounds during scheduled hours. When they leave campus, the watch automatically returns to normal mode.

How it works:

School Routine uses both GPS location AND the schedule you set. If your child is home sick, it stays off — no manual override needed.

Routines: What's Blocked and What's Always On

  • Fully restricted: only SOS will be available.
  • Partially restricted: call and message parent, guardians and 911 if enabled
  • Unrestricted: device will function normally.
  • When the Routine ends, the watch automatically returns to normal mode
  • Children cannot deactivate a Routine — Primary and Guardians can modify or turn it off.

Setting Up Other Routines

Beyond School-Fi Routine, you can set custom location and time based Routines — for example, getting notified when your child arrives home from school or leaves a friend's house.

  1. In the Cosmo app, tap Routines, then tap Add Routine.
  2. Name your Routine and set a location (search an address or drop a pin on the map or manually enter an address).
  3. Set the days and times for the Routine to be active.
  4. Choose the restriction level and notification preferences.
  5. Tap Save.
Tip:

Arrival and departure notifications are triggered based on your location update frequency setting. For faster notifications, reduce the update interval — but be mindful of battery impact.

Calls, Messages & Media

How Calling Works

Your child can only call and receive calls from approved contacts and guardians. Unknown numbers cannot reach the watch.

  • Incoming calls: Accept with the green button, decline with the red button.
  • To call someone: Tap the phone icon on the first app page, select a contact, and tap to call.
  • To adjust volume during a call: Tap the speaker icon in the top right.

How Messaging Works

JT5 SE supports real SMS texting with a real phone number. Your child can send and receive texts, photos, voice memos, and videos from approved contacts.

  • To open messages: Tap the blue message icon on the first app page.
  • Select a contact, then choose: keyboard text, image/video, or voice memo.
  • Preset messages: Your child can tap pre-loaded quick-reply messages. Or you can edit or remove  these in the Cosmo app under your Child’s profile, tap preset messages.
  • Voice to text: Tap the microphone icon in the message field to dictate a message, tap again to stop.

Group Messaging

The watch can be added to a group text of up to 8 members, as long as everyone in the group has been added as an approved contact or guardian in the parent app.

Reviewing Your Child's Messages

Parents can view the full message history from the parent portal (not currently in the Cosmo app). Log into Parent portal to view full message history.

Privacy note:

Your child cannot see when you review their messages.

Music Streaming

How your child activates SOS:

  1. Press and hold the side button for 5 seconds.
  2. A silent 15-second countdown begins to prevent accidental activations.

What parents receive:

  • An immediate push notification and alert in the Cosmo app
  • Automatic Live Tracking — location updates every 10 seconds for 15 minutes
  • Calling the watch while SOS is active connects silently — you can hear without your child knowing you're listening, unless they adjust the watch volume
  • An immediate push notification and alert in the Cosmo app
  • Automatic Live Tracking — location updates every 10 seconds for 15 minutes
  • Calling the watch while SOS is active connects silently — you can hear without your child knowing you're listening, unless they adjust the watch volume

Turning off SOS:

Only the primary parent can turn off SOS mode. Open the Cosmo app, tap the SOS notification or go to the watch controls screen, and tap Turn Off SOS.

Emergency Calling (911)
