Six data points. One question: is there a trend? LittlePlotter gives you a fast, beautiful answer. Type your values, swipe through eight curve types, and share a clean chart — in the time it takes to unlock your phone. No spreadsheet. No setup. No noise. EIGHT FITS, ONE SWIPE AWAY LittlePlotter covers the curves you actually reach for: • Line Segments — connect your points exactly as they are • Cubic Spline — smooth interpolation through every data point • Linear, Quadratic, Cubic — least-squares polynomial fits • Exponential, Logarithmic, Power Law — for data that grows or compresses nonlinearly The fitted equation is shown directly on the chart. If a fit can't be computed — wrong domain, too few points — the chart explains why. DESIGNED FOR SPEED The chart fills the entire screen. A single button opens the data table; edit your values and the chart updates live behind the sheet. Swipe left and right to move between fits, up and down to switch between fit families. Your data is saved automatically so you pick up exactly where you left off. SHARE-READY OUTPUT One tap exports a clean, high-resolution chart to your Photos. Press and hold for more: share via AirDrop, Messages, or any app, or copy directly to the clipboard. WHO IT'S FOR LittlePlotter is for anyone who works with measurements and wants a fast, clean answer: researchers checking a calibration curve, students visualising lab data, engineers sketching a trend on the fly, teachers making a quick diagram. If you've ever opened a spreadsheet just to plot six numbers, this was made for you.

Calendar is great, but sometimes it whispers when you need it to ring. Meeting, appointment and class reminders usually arrive as quiet notification banners that are easy to miss, especially on silent. Go Time rings for them instead: real alarms that work like your iPhone's own alarm clock, even on silent or in a Focus. Works with the calendar you already use Go Time reads the Calendar app, so iCloud, Google Calendar, Outlook and Exchange accounts you've added to your iPhone or iPad all work. Your calendar stays the source of truth; Go Time just gives it a louder way to reach you. Made for • Work meetings: an alarm before your Zoom, Microsoft Teams, Google Meet or Webex call, with a one-tap Join button when the event has a meeting link • Appointments: doctor and dentist visits, interviews, pickups, anything with a time that you simply don't want to miss • Classes and lectures: a heads-up before every class, without setting a dozen alarms by hand • Shifts and deadlines: if it's on your calendar, it can ring • ADHD and time blindness: when notifications fade into the background, an alarm still gets through • Alarms for a specific date: tap + to conveniently add an event to your calendar, and Go Time rings for it Features • Turn your calendar events into real iOS alarms, not notifications • A countdown to your next alarm, plus Home Screen and Lock Screen widgets • A focused alarm screen with a button to quickly join a meeting • Easily pause your alarms when you don't need them: for an hour, until tomorrow, until Monday, or until you resume • Smart rules (Pro): accepted meetings only, certain hours only, skip all-day or guest-free events, mute by keyword • Choose when each alarm rings (Pro): at the start, 30 minutes ahead, or any minute you pick, for all events or just one • Choose your alarm sound (Pro) Private by design: no account, no sign-in, and your calendar events stay on your device.
