We recommend the use of the NavTMS app provided by the Navigators. The cost is $4.99. Use this for memorizing these same 60 verses in the Topical Memory System (TMS). See, say and record the verses, and play several games to help you commit verses to memory. This app tracks memory and review status for multiple participants and gives points for their activity. This app shares memory status information across multiple devices via iCloud. Request if Spanish version is available if needed. Navpress also offers the cards with a case and a book for a reasonable fee if preferred.
Personally, I enjoy the benefits of using The Bible Memory App. Download it then search for the TMS (Navigators Topical Memory System). There will be five sections (A-E) of 12 verses each.
