Developer offered the option to remove adds for free some months ago and it was great not to have adds but in recent updates, that offered seems to have been rescinded as the adds are back again ...the developer also apologized for the ads and removed them. Unfortunately, the in the latest update, which was also flagged as unsafe by Google play secure, adds are back in the latest version. . Other than that, it's as accurate as anything else out there but obviously, untrustworthy.
