Review on AppVirality by Steve Campbell

I like that it is very simple, intuitive website layout with great graphics! Not much room left in this section of their toolbox but they did everything we needed at first go which was impressive considering how far along most providers were when compared from our needs or requirements (ease/interactivity etc.) The reporting could be more robust as well - perhaps adding some kind metrics related specifically towards app viraling rather than just general pageviews? This would make analysis easier down road too since you do have access now via API if need arises later).

We used them because one feature called "Referral" helps us track referrals within an entire chain so users can easily see who referred whom through out site's navigation structure without having all data stored directly under each user profile itself; making things cleaner overall especially while building new features into product roadmap such has auto referrer tracking.
