Write one line. LogBooklet remembers when and where. LogBooklet is a journal for iPhone and iPad. Type a thought, tap send, and the entry keeps the date, the time and the place on its own. No fields, no forms. ONE BOOKLET PER THING YOU KEEP TRACK OF A diary. The meals worth remembering. The plants. Quotes you want to keep. Make as many booklets as you like. The list shows how each one's latest entry begins, when you wrote it, and how many entries it holds. THE BEST PART COMES YEARS LATER Switch on time between entries for a booklet, and every entry shows the gap since the one before it. 9 days since you watered the fig. 6 weeks since you called your brother. 4 months since the last headache like this one.
