Halo put a new iPhone app in the App Store on October 11, 2026, and it arrives without the charts many owners used to follow their dog over weeks and months. The new Halo app, listed as Halo: GPS Dog Fence, has no activity graphs, no Pet Safety Card history and no Feedback Responsiveness Score, according to Halo’s help center, which was rewritten for it over the following week. Activity insights are due to return as part of a feature called Halo Health, with no date given. The old Halo Collar app is still in the App Store and got an update on October 12, so keep it installed if you rely on those trends.
What the old app showed and the new one doesn’t
In the old app, one Activity Tracker chart counted how often the collar gave Warning, Boundary and Emergency feedback. Another split the day four ways: safely inside a fence, outside it with fences on, fences off, and on the charger. A third tracked distance walked. The fourth sorted each day into active, resting and riding in a car. Their help page now says the charts “are not currently included in the Halo app.”
The Pet Safety Card, with its Safe, Unsafe and Tracking totals, isn’t available in the same format in the new app. In the old one it produced reports by day, week, month and year. The new app offers Walk History for now, with more health and activity insights promised in future updates.
Nothing replaces the Feedback Responsiveness Score’s long view either. It ranked your dog from 1 to 100 against other dogs wearing Halo collars, as a percentile and not a percentage, with charts by week, month and year.
Fence Events reset at midnight
In place of the score, the new app records Fence Events. Each time your dog enters the Warning zone, the app drops a numbered marker on the map and labels it Returned Successfully or Delayed Return.
Because the markers reset at midnight each day, they suit a new owner checking how the first days of training went. They don’t replace the monthly chart for an owner who wants to know whether a dog that kept slipping past the boundary in August behaves better in October.
The App Store page still lists activity tracking
The new app’s own App Store description still has an Activity Tracking section. It says the app “logs your dog’s location, number of walks per day, and time spent active, resting, or in the car.” The help center says those charts aren’t in the app. Until the listing changes, read the help center as the current answer.
Walk tracking, which the release notes on the same page describe as new, shows speed, distance and time and ends with a summary of the walk. Collar firmware 3.9.46, the current release, already records a walk as a trail and detects when it starts and ends. The notes also promise live location updates up to four times per second. A tracker like the Tractive DOG 6 updates every 2 to 3 seconds in LIVE mode, and its virtual fences send an alert to your phone when the dog crosses one.
The old app let you replace outdated satellite imagery for up to 50 areas, choosing between sources such as Google and Bing. The new one uses Apple Maps on iPhone and keeps them up to date automatically, so that setting is gone.
Which phone you need
The new app requires iOS 17.0 or later, so an iPhone 8 or iPhone X, which stopped at iOS 16, can’t install it. On those phones only the old Halo Collar app runs. Halo’s phone requirements page in the help center, last updated July 29, still lists iOS 14 as fully compatible, which no longer holds for the new app.
Android owners have nothing to change yet. The rewritten help articles list the Android version of the current app as “In Development” and keep the old app’s instructions alongside. Those articles call the old app version 2.15 or earlier, though its iPhone listing reached 2.16.1 on October 12.
Before you switch on an iPhone
If you check the yearly safety report or the responsiveness chart, open them in the old app first and take screenshots of the months you want to keep. Then install Halo: GPS Dog Fence beside the old app instead of in its place.
Halo hasn’t said whether the history behind the old charts will move into Halo Health, or how long the old app will keep working.
