I have been using this form app for several months and it works great at this price. The thing i think this platform needs to improve is the "Conditional" feature, including multi conditional feature as well as "if <condition> go to <this page>" feature. But i think both are in progress? If it is done, the price should be up another $10, at least :)

Update: I gave 5 star but downgraded to give 4 star for this app because suddenly today i noticed we can run the form every 2 minute (strange, why you suddenly change it to 2 min?) . Last week, i can run within 1 minute.
