Too many other very good FREE apps available that are not intrusive and a pain in the A.... ### 1/5 — Annoying *2018-08-18* taking it off system repeated ads every 60 seconds, an over lay for other advertisemant cant be eliminated, no way to save the screen setting , Another idea gone bad because of advertising, - No access to settings or ability to save screen size ### 1/5 — Does not disclose that it has ads. *2018-08-09, version 2.0* App does not disclose that it has advertising. I do not want an app with advertising, especially one that does not disclose that. ### 1/5 — Faulty *2017-09-07, version 2.0* Great opening view of the whole US allows you to zoom in on any area of the country. Then you get a random pop up ad and the app freezes. You have to shut down and start over. Faulty code. Don't waste your time. ### 2/5 — Не многовато ли рекламы? *2019-04-09* Рекламные ролики перекрывают экран каждые 25-30 секунд... не преувеличиваю, засекала. Раздражение перекрывает полезность. ### 2/5 — 無數據的顏色 *2018-05-13, version 2.0* 不應是綠色的！可考慮用淡灰的，就像無功能的icon！ ### 5/5 — 2.0 *2018-01-05, version 2.0* 2.0 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
