Fantastic story and great songs. Highly recommended for children and thier parents!! ### 5/5 — Great story and music for kids!! *2021-04-18, version 2.2.0* My children loved the story and songs!! I got it when my oldest was four... he’s now 10 and still remembers it... one of the characters made a specially lasting impression: the Registrar. Highly recommended!! ### 4/5 — Lovely app for kids *2020-04-20, version 2.1.7* We downloaded all 4 parts of the app for our kids. My 8 year old finds them very relaxing to watch and listen too, the music is really good. ### 5/5 — Great story about Rockford *2018-09-22, version 2.1.5* The registrar should be arrested. I like Rockford, the thing I must know why the registrar is trying to make everyone become extinct. Why do the animals not like humans. ### 3/5 — Doesn’t download *2018-03-18, version 2.1.4* After multiple attempts at downloading this it just doesn’t play back any videos. Pt 1 worked fine but there seems to be a bug with this ### 5/5 — Part 2 Does not download properly! *2018-03-01, version 2.1.4* Doesn’t download part 2 properly, just wont play and constantly says downloading? ### 5/5 — Brilliant *2015-01-05, version 2.1.2* This story (and parts 1, 3 and 4 too) have been a huge hit in this household over recent weeks and the situation shows no sign of changing. My 4 and 6 year old girls are even more enthusiastic about Rockford than they are about Frozen! A visual and audio treat. ### 5/5 — The rockford rock opera *2014-03-18, version 2.1.2* What a book ### 5/5 — Brilliant!! *2013-09-21, version 2.1.0* I absolutely love this whole set. My kids 6 and 4 years both love them and would play them repeatedly given the chance!! Gorgeous pictures, fantastic music and a brilliant message so well told. ### 5/5 — Emma *2013-05-14, version 2.1.0* Fantastic story,songs and animation. My daughter and I love it and have watched it over and over again. Have recommend to friends and they love it too! ## Frequently asked questions about Lost on Infinity ### What is Lost on Infinity – Audiobook 2?
