Tile, which makes bluetooth labels that people can use to find their stuff, has been critical of Apple's AirTag.
The manufacturer indirectly labels the AirTag as "unfair competition,"
Apple announced the AirTag on Tuesday;
a product that does much the same as Tile's bluetooth label.
Tiles smart labels and the AirTag both work via bluetooth.
Within a short distance, both labels will beep.
Both Tile and Apple have their own search network for their labels.
"We welcome competition, as long as it's fair," Tile CEO CJ Prober wrote in a statement.
"Given Apple's use of its platform advantage to unfairly restrict competition for its products, we're unfortunately skeptical."
Apple points out to the company that Find My functionality has been around longer than the Tile brand and that the network is also open to devices from other companies.
However, third parties must pay commission to use the Find My network.
For example, Tile users who want additional features must subscribe, while Apple's own devices do not.
Tile has to hand over about 30 percent of the proceeds from the subscriptions to Apple.
Tile will talk to the US Congress about this arrangement on Wednesday, together with music service Spotify and tech company Match.
"We would consider it appropriate for Congress to take a closer look at Apple's practices," said Prober.
