350 requests/hour per App


Hi everyone,
I’ve developed a web-based app to retrieve latest statuses from users with public timelines, meaning that I don’t need their authentication to read their statuses. The problem is with rate limiting, the 350 requests/hour are available per user (access token), but in this case, I have a registered app with consumer key and consumer secret but no users access tokens.
I’ve tried to use my own access token but that would only allow me to get my own data. Is it possible to make 350 calls per app?
