To celebrate the beginning of the weekend, we thought that it would be nice to do an app giveaway.

Once again, there is nothing special for you to do. All that matters is that you be fast at redeeming one of these codes, because they will go away very quickly. But before we start, make sure you know how to redeem a promo code in the App Store…

We want to thank the developers who made this giveaway possible: Ville Helin, Alex Trott, and Kevin Dixon.

If you’re a dev and want to have your app given away on iDB, get in touch with us.

AC Wizard

This app definitely won’t be interesting to everyone, but there might be some of you out there who’ll find it useful. AC Wizard is a comprehensive heat load calculator and air conditioning sizing tool.This App is aimed at the complete novice and the hardened air conditioning engineer.
