What’s new

This update adds a recurring Rate App + Support Developer reminder system. The first reminder appears on the 10th app opening, then every 30 openings after that. Rating is offered once, while the optional $1 Support Developer purchase remains available for repeat support. Google Play in-app update checking remains included, and timer functionality is unchanged.
