The books they grew up with. TumuBook is a reading log for parents and kids. Keep every book your child reads, with the date and how old they were. "The picture book they asked for again and again as a baby." "The book they practised reading with in first grade." Books carry a picture of who your child was at the time. Note what they read, when, and how old they were, and the record becomes a memory in itself. One book finished, and what next? With no time to look, or no quick trip to the library or bookshop, that eagerness to keep reading can quietly fade. TumuBook lays out what might come next from the books they've read: "if they loved this one, here are a few more." A natural moment to ask, "Want to try this one?" SECONDS TO LOG. YOURS TO KEEP. - Scan the barcode to add a book - The date and your child's age are saved automatically - Add a note if you like - Browse each shelf by age or by month A SHELF FOR EACH CHILD - A separate shelf for every child - Whatever the age gap, all in one app MORE TIME WITH BOOKS - Picks like "Because you read…" and "More by the same author" appear on the Home, grown from the books they've read - Save the ones to read next, and check the list on your next trip to the library or bookshop SERIES AND NEW RELEASES - See every volume of a series, with a tick on the ones they've read - The next volume shows up on the Home - We keep an eye on new releases in the series they read WORKS ON IPHONE AND IPAD Made for parents who want to: - keep the books their child reads as memories - log every sibling's reading in one place - spend less time hunting for the next book - keep track of library books as well as their own
