val isZerionInstalled: Boolean = isPackageInstalled("io.zerion.android", packageManager)

private fun isPackageInstalled(packageName: String, packageManager: PackageManager): Boolean {
    return try {
        packageManager.getPackageInfo(packageName, 0)
        true
    } catch (e: NameNotFoundException) {
        false
    }
