Trial Period for In-App Purchases

Now you can test-drive any of our modules for 7 days for free, and after that time you can choose to buy the option, or leave it locked. There is no obligation for this, it does not require you to cancel before the end of the trial period. Note that we did not implement this for the All-in Option, it is only valid for the individual modules.

"All-in" Options

Unlock All AudioTools Modules (except STIPA Pro) $349.99 -- 45% discount

This option is the best value, and represents at least a 45% discount off of the individual module prices. Note that there is no credit for already purchased modules. This (and all in-app purchases) are available on all of your iOS devices that are logged into the same iTunes Store account. Most future modules are also planned to be included in this option, although we reserve the right to exclude a very extensive or special-purpose module.

Unlock Everything $399.99 -- 45% overall discount + 66% STIPA Pro discount! (coming in AudioTools 10.11)

Get the entire app, including STIPA Pro at a great price. This is currently a $780.00 value. All future modules are also planned to be included in this option, although we reserve the right to exclude an extremely special-purpose module. 

New! Upgrade Calculator

The Upgrade Calculator will inspect the app for already installed in-app purchases, and pro-rate the full upgrade cost by the approximate percentage of apps that you already have bought. You will then be presented with the oppurtunity to purchase this upgrade, which has the same benefits as the Unlock Everything option (above).

Note that depending on your previous purchase history, you may be presented with a one-time discount. Note that if you do not use it, the discount will expire and not appear again.

Module Pricing
