What's New in Greyline FT8

1.4.0

August 29, 2026

“The one that finally integrates World Radio League” **NOTE** - The WRL logging API is a work in progress, and I will continue to improve the app as their API evolves! What we have here now takes full advantage of what the service currently supports. Stay tuned for more features! Be sure to check the release notes for prior versions to see what's new! I update the app regularly in response to feedback like yours. Read them at https://greylineft8.com/changelog.html Remember that Greyline now has a comprehensive user manual at https://greylineft8.com/userguide.html - you’ll also find a button in the Settings view to take you there Shoutouts: KR3BST - Frequent reminders about WRL integration Features: - Greyline now uploads your contacts to World Radio League (WRL), alongside QRZ and Cloudlog - POTA activations get their own logbooks in WRL (named for your callsign, the park and the date) - this can be turned off and your contacts can land in your default logbook instead - Log uploads now have robust retry and error messaging. As the logging system in Greyline gets more complex and supports more endpoints, clear errors are important - Contacts which failed to upload to a configured service show an X in that service's color in the Upload column instead of an empty (or filled) dot, so you can spot them while scrolling. Fixes: - Because we incorporated an X in the upload status column, the service indicator color for QRZ has been changed from green to teal, to avoid confusing “green X’s” That’s it, that’s all, folks! Thanks for bringing me on your activations - now get out there and POTA on. 73!

OUTSTANDING!!!

Started this program as a lightweight alternative to other FT8/FT4 programs. Using this App with the QMX and iPhone reduces weight astronomically, allowing for both POTA and SOTA. It functions extremely well, and the Hunter/Gatherer modes are a total hoot. This is so far, the best App for the aforementioned digital modes I’ve encountered so far. Kudos to Jon for creating this gem!

I’m so glad you’re enjoying! The iPhone is how I always imagined the app being used so it makes me really happy you’re getting out there with a pocket station. Not that I don’t love my iPads too. Keep hunting and hope to catch you down the log! 73 KB0RB

Absolutely Fantastic App!

Kudos to the developer, this is a POTA game changer having the ability to use my iPad for FT8 vs lugging a laptop around. Incredibly easy setup, I was up and running in minutes, no configurations, just a few settings and you’re on the air! Thanks for all your hard work on this.

Response from developer

Hey thanks for the note! Glad you’re enjoying and keep watching the updates for even more POTA goodness!

Great customer service and app!

Update: After my review, the developer messaged me and we discussed what was going on, and my issue has since been resolved. I also found another possible small bug, and he’s working to resolve it as well. He is truly dedicated to making this an awesome experience!
A+++

I’ve been using iFTx for a while and it’s ehh at best. Bought this app the other day and at first I loved it. The features and UI are awesome and easy to use.
Once I started actually using it, I realized I wasn’t hearing much and when I compared the signal reports to iFTx, Greyline was giving a much lower signal report vs the other app. Example, on Greyline, I was seeing one station coming in a -18 to -24, where with the other I was seeing the same station(within a minute or two) at -2 to -4. I would call CQ and no one would respond, but switched to iFTx and I’d get several people calling back.
When I checked the map, I was being heard by close to 300 other stations, so I know it’s not an issue with getting out.
I hope this can get resolved as I do honestly like the look and feel of this app better than anything on iOS.

Hi there and thanks for the report! I haven’t had anyone else mention this discrepancy between apps. I’ve tried myself on the same device with iFTX and Greyline and never observed it either. I did use the two side by side to refine some timing algorithm issues early in development so I definitely appreciate the science of your approach. Greyline applies the exact same logarithmic equation to compute SNR as any other application, so I need to do some digging to understand what could be a problem here. Nothing else was different between your setups? Please contact me on support@greylineft8.com and we can discuss further.

Love the features, but decoding seems off.

I like it but . . .

Great performance, easy to use. Good graphics. Currently using it with my Yaesu FT-891 and my QRP_Labs QMX+. Please upgrade the app to allow me to use my Yaesu FT-991A.

Response from developer

Hi there! There shouldn’t be any reason you can’t use it with a 991A. Please let me know what problem you’re seeing at support@greylineft8.com and I’m sure we can figure it out.
