# Detecting Seeker Users
Source: https://docs.solanamobile.com/recipes/general/detecting-seeker-users
This guide outlines the two primary methods for identifying Seeker users within your React Native application. Choose the appropriate method based on your requirements and use case.
## Overview
There are two main approaches to detect Seeker users:
1. **Platform Constants Check**: A lightweight client-side check using React Native's Platform API
2. **Seeker Genesis Token Verification**: A secure on-chain verification method
## Method 1- Platform Constants Check
The Platform Constants method checks device information using React Native's built-in [Platform API](https://reactnative.dev/docs/platform). This is a quick, lightweight check suitable for UI treatments and non-critical features.
