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. **Developer response:** 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. ### 4/5 — I like it but . . . *2026-07-31* 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. **Developer response:** 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. ### 4/5 — Need tech support suggestions wrong entity comes though *2026-06-26* Developer responded, sent error screen shots! Looking forward to seeing these bugs fixed :)) ———— Hello!! I love the features but the entity comes up wrong on the grid. I am in Iowa and it shows as IL. Also getting IPAD sound disconnection errors **Developer response:** Hi there - I need more information to track this down. Please email at support@greylineft8.com and I’m sure we can figure out the issue. ### 4/5 — Need tech support suggestions wrong entity comes though *2026-06-22* Hello!!

Worked well once I dialed down the levels on the radio. Would be nice to have input/output level control in app to avoid having to readjust in the radio for each app I use. Also, on my ipad mini, the decodes text font size is a bit small. Ability to increase font size would be a bonus. Will be using it again for sure. I recommend it as a great improvement over iFTx. Thanks! **Developer response:** Thanks for the note! Your input control is the volume buttons on your device - it automatically compensates for incoming volume as well as it can. Glad to hear it worked well for you on the 891! I will consider adjustable font sizes for the future but accounting for individual taste there can be tough with a carefully laid out UI. Did you try portrait mode on the iPad? It should default to a layout with more spacing if you do. Keep activating and 73 😁 ### 5/5 — OUTSTANDING!!! *2026-08-26* 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! **Developer response:** 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 ### 5/5 — Absolutely Fantastic App! *2026-08-08* 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. **Developer response:** Hey thanks for the note! Glad you’re enjoying and keep watching the updates for even more POTA goodness! ### 5/5 — Great customer service and app! *2026-08-07* 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!

This app is easy to use, a familiar look, and does a great job of uploading contacts! Another great feature is the help section...which lays out exactly what you need to connect your radio to make it work. Thanks for making this! **Developer response:** So glad you’re enjoying and especially appreciate the feedback on the help section. I put a lot of love into that because I know people often are confused about how this magic actually works with the equipment they already have.
