Short answer: Sorapuff is a calm flight buddy for iPhone and iPad. Before you fly it forecasts the likely bumps on your route from free public weather data; in the air, in airplane mode, it measures each bump with your phone's sensors and puts it in perspective. It's free to download, and Sorapuff Pro is $14.99 once, with no subscription. It offers information and calming tools, never medical advice, and you should always follow your crew.
FAQ
What is Sorapuff?
An iPhone and iPad app for people who feel nervous about flying. It has a route turbulence forecast, a live bump meter that works in airplane mode, a big flight tracker with tips, breathing with gentle haptics, a calm button, calm music made on your phone, Sky Cards to collect, and Sora, a little Sky Keeper who explains everything kindly.
How does the turbulence forecast work?
You enter the two airports and the departure time. Sorapuff downloads only the wind data along your route from NOAA's free GFS weather model, computes a well-known clear-air turbulence index along the way, and adds storm warnings (SIGMETs) and recent pilot reports from aviationweather.gov. You get a minute-by-minute timeline: smooth, light or moderate. It's a likelihood, never a promise, and "severe" only ever comes from an official SIGMET. More in how turbulence forecasts work and what PIREPs and SIGMETs are.
Is turbulence dangerous?
For a seated passenger with the seat belt fastened, turbulence is uncomfortable rather than dangerous. Airliners are certified to carry 2.5 times their own weight (2.5 g) without any damage, and 1.5 times that before anything would fail. Normal flight is 1 g, and light turbulence changes it by only a few tenths of a g at most. Most turbulence injuries happen to people who are standing or unbelted, so keep your belt on when seated and follow the crew's instructions. More in Is turbulence dangerous?
How can the bump meter work in airplane mode?
It needs no network. Your phone's motion sensors and barometer feel each bump and each phase of the flight (climb, cruise, descent) right on the device. The meter shows the bump in g next to what the airplane is built for, and a calm needle that doesn't jitter.
Does Sorapuff replace therapy or medical help?
No. Sorapuff offers information and calming tools. If fear of flying weighs on your life, a fear-of-flying course or a professional can help. On board, always follow your crew. Our fear of flying guide explains what helps.
How much does Sorapuff cost?
Free to download, with the bump meter, the flight tracker, breathing, the calm button, one route forecast and the first three Sky Cards. Sorapuff Pro is $14.99 once (US price): unlimited forecasts up to three days ahead, the route map, every Sky Card and outfit, all music moods, the widget and the Live Activity. No subscription, and Family Sharing is included.
Is my data private?
Yes. There's no account, no analytics and no ads. Your flights stay on your phone. Weather data is downloaded straight from public sources. Read the Privacy Policy for every detail.
How do I add a flight?
Pick the airports and the time, or let Sorapuff find it for you: paste your booking email, open a PDF or a Wallet pass, or scan the barcode on your boarding pass. It can also look for flight bookings in your calendar or, only if you choose to connect it, search your mailbox read-only for flight bookings. Everything is read on your phone.
What is "Help Sora learn"?
After a flight, Sorapuff can ask whether you'd like to send that flight's bump readings to help us check and improve the forecast. It's optional, asked per flight (or "always send" if you pick it), and anonymous: two airport codes, the departure hour, the saved forecast and the bump readings, never your name, email address, device or location. You can see exactly what's sent before sending.
Does Sorapuff show delays, gates or live positions?
No. Sorapuff doesn't track flights online. Its tracker follows your flight from the schedule and from what your phone feels, so it works in airplane mode.
Does it work on iPad, and in my language?
Yes: iPhone and iPad with iOS or iPadOS 18 or later, in 18 languages.
Who are Sora and Puff?
Sorapuff's own characters: Sora, a chibi Sky Keeper with a paper-plane wand, and Puff, her winged cloud-bunny. They're original to the app.
