Will updates for 2Do be free?
Yes. But not ’forever’. From v1.0 to v3.0, however, we have always announced it as a free update. We will endeavor to provide you with free updates for as long as it’s feasible to do so and may resort to optional in-app purchasable upgrades if certain features we work on are considered optional.
If the App Store does not inform you about 2Do’s update or you don’t see it in the updates list, simply click/tap on ’Buy Now’ again in iTunes to download the update for free. As long as you are using the same iTunes account, you will not be charged again.
