Short answer: Turbli is the better pick for a free turbulence forecast on the web, for turbulence maps of the whole sky and for a forecast built on NOAA's dedicated turbulence product. Sorapuff is the better pick for help during the flight itself: a bump meter that works in airplane mode, breathing with haptics and a calm button, with no account and one $14.99 payment instead of a subscription.
We make Sorapuff, so read this with that in mind. Every Turbli fact below comes from Turbli's own website or its App Store listing, checked on November 13, 2026, and is linked under Sources.

What Turbli does better
- It's free on the web. You can check a flight from any phone, Android included, or from a laptop, without installing anything.
- It uses a turbulence product made for the job. GTG is NOAA's purpose-built turbulence guidance, and Turbli shows its strength in eddy dissipation rate (EDR), the standard unit NOAA uses [3][6]. Sorapuff computes one well-known clear-air turbulence index from NOAA's GFS winds.
- It knows more about your flight. It adjusts for the aircraft type, and for US flights it uses the route and altitude in the filed flight plan [3].
- It has maps and history. Turbulence, wind and thunderstorm maps, historical data and a yearly ranking of the most turbulent routes [6][8].
- It's been around since 2020, and you can download its app today. Sorapuff isn't on the App Store yet.
What Sorapuff does differently
- Help in the air, not only before. A bump meter measures each bump in g with your phone's sensors and puts it next to the 2.5 g an airliner is built for. It works in airplane mode, and so do the tracker, breathing, the calm button and the music.
- Pay once. $14.99 for Pro, with Family Sharing: less than one year of Turbli+ ($19.99), and nothing after that. Turbli's website, though, costs nothing at all.
- No account, no analytics, no ads. Your flights stay on your phone.
- 18 languages in the app.
- Severe only from official warnings. Sorapuff shows smooth, light or moderate from its own forecast, and says severe only when an official SIGMET does.
Which one should you choose?
- You only want to check a flight before you go: Turbli's free website is hard to beat.
- You want a turbulence map or historical route data: Turbli.
- The fear peaks once you're in the air: Sorapuff, for the bump meter, the tracker and the calm tools that work offline.
- You don't want another subscription or account: Sorapuff.
- Both: many nervous flyers check the forecast on the web, then keep a calm tool for the flight itself. The two don't conflict.

FAQ
Is Turbli free?
The turbli.com website is free to use and is supported by ads and donations. The Turbli+ app for iPhone and iPad needs a subscription, $4.99 a month or $19.99 a year in the US, and an account [1][4].
Does Turbli work in airplane mode?
The Turbli+ app keeps your flight history available offline [1]. Its forecasts and maps are made before you fly. Sorapuff's bump meter, tracker and calm tools are built to work in airplane mode.
Which turbulence forecast is more accurate?
We haven't tested them side by side. Turbli uses NOAA's dedicated GTG turbulence product and your filed route for US flights, which is richer data than Sorapuff's single index. Turbli itself says turbulence forecasts are most useful about two days ahead [5]. Treat any forecast as a likelihood, not a promise.

No. Sorapuff is free to download, and Sorapuff Pro is a one-time purchase of $14.99 (US price), with Family Sharing included.
