If you have an Android handset, you may be interested in Appon's Thai Recipe Android application for this site. It lets you browse all the recipes on this site, filter by ingredients and exclude recipes that contain ingredients you don't like. It requires network access, runs in low, medium or high resolution modes, and is free... or rather it's paid for by advertising. If you like the application, don't forget to vote for it with the Google+1 button. The more votes I get. the higher I rank.
For problems, please contact ApponKhiewchanta at gmail dot com and I'll pass them to the developer to be fixed.
For iPhone users there's our mobile recipe browser, which should also work on other mobile phones too. Again this is free to you, well as long as you don't mind adverts.
