You can use the error handling, with something like that :

use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpKernel\Exception\HttpException;
use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;

$app->error(function (\Exception $e) use ($app) {
if ($e instanceof NotFoundHttpException) {
        return new Response('The requested page could not be found. '.$app['request']->getRequestUri(), 404);
    }
    $code = ($e instanceof HttpException) ? $e->getStatusCode() : 500;
    return new Response('We are sorry, but something went terribly wrong.', $code);
});
