Deceptive Practices – Lumen Tracker - Health, Fitness & GTD Hub Review

The developer, Lumen Spark, previously sold the older version of this app (8 versions in different colors with slightly different names) for as much as $19.99. Then they introduced this app as v10.3 and simultaneously updated the other versions to v10.3, which they described as "Added an option to use Lumen Trails for free with ads, and introduced an optional monthly subscription, which removes ads and supports future development." But that updated simply introduced advertisements (and no new features) in an attempt to push existing purchasers of the app to buy a paid subscription to remove the ads. They did not ADD an "option to use Lumen Trails for free with ads"--existing paid customers could already use the app without ads.
