What's New in Omamori Anti

1.9

September 2, 2026

New • History What happened each time you were away from your iPhone: when it started, how long until you were back, and whether the alarm rang. A column of “Reconnected on its own” is the evidence that the guard has been running. Kept on your devices only, and never sent anywhere. • Ring from the watch face The card on your Apple Watch face now has a button to ring your iPhone. It appears while the link is up. Fixed • More reliable reconnection After the iPhone app was replaced — an App Store update, for instance — the Watch could sit on “connected” while the guard was in fact running on neither device. Every connection is now verified rather than assumed. • The language you choose in the app now reaches the alarm notification and the history too, not just the screens. • The Apple Watch screens are tidier: pairing state is part of the status card, and unpairing moved to the bottom of Settings. • The usage guide has two new pages, and all four languages were reread.

Background app is off

Hello Omamori Support,

I am currently testing Omamori with my iPhone and Apple Watch during the 7-day trial.

The separation alert works correctly: when I move away from my iPhone, my Apple Watch alerts me as expected.

However, I have a problem with the automatic reconnection. When I return and my Apple Watch is again close to my iPhone, Omamori remains “Disconnected” on the Apple Watch. It does not reconnect automatically.

As soon as I open the Omamori app on my iPhone, it immediately changes to “Connected – Apple Watch linked.”

I have already confirmed that:

* Bluetooth access for Omamori is enabled.
* Notifications and sounds are enabled.
* The Apple Watch remains paired.
* Omamori does not appear as an option under iPhone Background App Refresh.

For an anti-loss application, automatic reconnection is very important because I should not have to remember to open the iPhone app every time the devices come back within range.

Is this the expected behavior, or is there a setting I need to change to make Omamori reconnect automatically in the background?

I would like to resolve this before subscribing after the trial period.

Thank you for your help.

Response from developer

Hi Rubén — thank you for testing this carefully. The detail in your report made it easy to work out what is happening, and it was specific enough to change the app, so thank you twice. Short version: the app is not broken, and there is a way to get reconnected without taking your phone out. How the link works: your iPhone is the side that advertises, and your Apple Watch is the side that connects to it. The Watch can only reconnect while the iPhone app still exists as a process. Backgrounded is fine — iOS keeps advertising on the app's behalf and the two find each other again on their own. But if Omamori has been swiped away in the App Switcher on the iPhone, iOS will not relaunch it for a Bluetooth event, and nothing on the Watch can reach it until you open it again. That matches what you describe exactly: opening the iPhone app makes it connect instantly. Two things to try right now: 1. Open Omamori on the Apple Watch, not on the iPhone. The watch app kicks a fresh reconnect when it comes to the foreground, which in many cases restores the link without touching your phone. 2. Leave Omamori in the App Switcher on the iPhone. A backgrounded app keeps advertising and costs you nothing; swiping it away is what breaks the automatic reconnection. Your report also changed the app. In the update being submitted now, the Watch no longer just says "Disconnected": when it has not managed to reconnect after a few seconds, it explains that the iPhone app may have been closed, and offers a retry button. To be straight with you, this does not change what iOS does — an app you swiped away still cannot be relaunched for a Bluetooth event, and no app can change that — but you will be told that is what happened instead of having to work it out from the outside. On Background App Refresh: Omamori not appearing in that list is expected, and is not the cause. That list only covers apps that use background fetch. Omamori uses the Bluetooth background mode instead, which is not shown there and does not need to be switched on. One correction, since it affects your decision: there is no subscription. Omamori is a one-time purchase, so nothing recurring starts when the trial ends. If neither step above helps, please write to support@glspace.co.jp and mention this review — a case where the link does not come back on its own while the iPhone app is running is worth looking at closely. — Omamori Support
