Napkin is a notes app that calculates, on iPhone, iPad and Mac. Write a line, end it with =>, and the result appears behind the arrow.

CALCULATE IN YOUR NOTES • Variables, including names with spaces: rent = 1100, per day = left / 30 => • Your own functions: f(x) = x^2 + 1, then f(4) => • Units and conversions: 26.2 miles in km =>, 50 km/h * 30 min => • Unknown names stay symbolic: 2 * y + 3 * 4 => 2y + 12 EQUATIONS • 6x = 30, then x => 5 – the unknown is solved and defined • Units too: speed * 2 h = 100 km => speed = 50 km/h • Systems: x + y = 10 and x - y = 2 give x = 6, y = 4 • Comments after # stay out of the calculation PLOTS • plot(sin, cos, -pi, pi) draws the curves right under the line • Functions you defined, expressions in x, or a list of numbers SONGS AND THE STAGE VIEW • Chords in brackets, as in ChordPro: Smoke goes [G]up and the [C]stars come out • The stage view shows a song full screen, chords above their syllables, scrolling up at the speed you set • The text fills the screen's width; the screen stays on TAGS • Label notes, for example Song, then search #song to list them • Notes with chords count as songs without a tag • Tags stay with the file: they show in the Files app and the Mac's Finder MARKDOWN, STYLED AS YOU WRITE • Headings, bold, italic, code and quotes are styled in the editor • Bold, italic and links from the menu over a selection, or ⌘B, ⌘I, ⌘K on a keyboard • Tables, and Convert to Table for lines in columns • [[Links]] between notes, and tappable web addresses FAST NOTES • One field to search and to create: type, press Return, and you are writing • The words you searched for are marked in the note; find in a note with the find bar • Hide notes you rarely need; a search still finds them YOUR FILES, ON ALL YOUR DEVICES • Every note is a plain Markdown file in a folder you choose, for example in iCloud Drive • In iCloud with one tap: Napkin on your iPhone, iPad and Mac finds the same notes by itself • A note changed on two devices at once is kept twice, never overwritten • Buy once: Napkin for Mac, iPhone and iPad is one purchase Napkin collects no data and makes no connections of its own. ## Is Napkin safe?
