No.

The first release of Trolling Angles provided a free limited-feature version with banner ads. However, this option was discontinued because it increased the app’s complexity and because revenue per ad click is miniscule.

If you want to try before you buy, activate a one month subscription, which provides a one-time free month before payments start. If it is cancelled before the month is done, you can still use the app for the entire month without cost.

A year’s subscription costs less than a couple of lures or a couple dozen minnows. A permanent license costs less than a spool of good braided line. It’s a very good value for software of this complexity and quality.
