A modern charm for your keys and wallet.
MAMORIO is the official app for the lost-item prevention tag that lets you trace "when and where" your belongings were last seen.
Not GPS — a Bluetooth crowd-sensor network.
That's why MAMORIO is thin, light, and long-lasting on battery. Comfortable to keep on your keys or in your wallet, all year round.
What this app does
- Set up and manage your MAMORIO tags in minutes
- Notify you the moment your tag is out of range (left-behind alert)
- Show the last detected place and time on a map (history, not real-time tracking)
- Turn "Find with Everyone" (crowd tracking) on or off
- Receive alerts from MAMORIO Spot stations (Japan only)
- Get an email if your iPhone itself reaches a partnered lost-and-found center
■ Left-behind alerts, the moment it matters
The moment your iPhone stops detecting your MAMORIO, you'll get a notification.
A small heads-up before you leave the table, the train, or the meeting room prevents most forgotten items.
■ Trace "when and where" — on a map
View the last place and time your MAMORIO was detected.
MAMORIO does not stream a live location. It records each detected moment as history, so you can retrace where it might be.
■ Find with Everyone — crowd tracking (Patent No. 5894309)
A unique feature that uses the network of MAMORIO users to quietly search for your missing item.
When your MAMORIO is not nearby, a "Find with Everyone" button appears.
Turn it on, and whenever another MAMORIO user passes near your tag, the place and time are sent to your app.
* No information about your MAMORIO is shared with other users.
■ MAMORIO Spot — partnered lost-and-found counters (Japan only)
In Japan, major train stations and commercial facilities are equipped with MAMORIO Spot devices.
When a missing MAMORIO arrives at a Spot, the location is delivered to your app.
The current list of partnered centers is available in-app. (Requires "Find with Everyone" to be on. This feature is currently available in Japan only.)
■ When your iPhone itself is found (Japan only)
If the iPhone running this app is turned in to a partnered lost-and-found center in Japan, you'll receive an email at your registered address.
You can use this feature even without owning a MAMORIO tag.
* Configuration via the app or web is required. The list of partnered centers is available in-app. Currently limited to Japan.
Before you start
■ There is no GPS chip inside MAMORIO
MAMORIO records a history of "when and where" your item was detected.
It cannot stream the live position of an item that has left your side.
In return, MAMORIO is remarkably thin, light, and long on battery life. It is not suitable for real-time tracking of children, pets, or elderly family members.
■ About location data
Location is obtained via your iPhone's GPS and network signals. Accuracy may vary by signal conditions and environment.
For background detection, we recommend setting Location to "Always Allow".
■ Effective range (Bluetooth)
Communication range varies by product model and can be shortened by walls, crowds, or interference.
