Good start if this is a work-in-progress. Needs much more development of screen entry logic, date fill automation, call sign lookup. Far from being worthy enough to charge for. Keep working at it and make it free until it is tested and ready for distribution.

Relatively easy to learn and use this effective QSO logger. I miss the presentation layout of a paper log in finding a particular QSO or browsing for an unfamiliar callsign from the past, although this is a rarity. It is great to still have an independent logger for an android device, giving it portability. Thank you.

Great app, getting better all the time. If possible, plz add date to QSO search results. It shows time without date, which is very not useful. And Dark theme would be very welcome addition. Thank you, keep up the good work, 73!

An excellent log book. This is the perfect log book for working portable or away from home. I used to enter my contacts into a paper notebook when portable or in the garden and now use this on my phone or tablet. When entering a contact I would prefer the call sign of the station to be the first entry and not halfway down the page as its the most important bit of information. I will certainly use this when away from the QTH.

Never done one before so I took a Chance. Glad now I did. it is better then I first thought. I have since downloaded a few more to compare. And so far this app is in my opinion better. I shall keep this app. Thank you for a Logbook app that does not have loads and loads of adds. I shall be happy to make a contribution in the very near future.

Crashes every time I try to export adif file. Frustrating after entering dozens of contacts and losing them. Play Store says "app may not beoptimized for your particular device. Running on Kindle Fire HD 8, 6th gen.

Great app, It basically has everything we need to record the QSOs among other features, the developer is very proactive and is well integrated with the users, I'm really enjoying the experience!

Having a hard time figuring how to purchase the app?

Unfortunately, this app does not work on my Galaxy Tab A. It can't find universal time. It does not dislay the correct date or time in the log book. I wish it worked, but it doesn't.

Bru. W. Mar 9, 2021     

Seems like a good app. I have barely used it and still need to figure it out. Not sure if when I hit next that it means next QSO or not? Need to play with it to see if it will work for POTA

Joh. B. May 31, 2021     

Simple, configurable, semi-automatic. Very well designed. Love this app.

Spe. M. Jan 28, 2020     

I like how you can enter in all your operation information and it saves it. Then just type in the contact information and hit next and you don't have to start from scratch.

Dan. T. Oct 7, 2021     

Great app! Would love to buy the premium version but pressing the premium button only describes the premium features. Where to purchase?

The most useful android log I have found, happy to donate and support its development. Well done and thank you. 73's

Its a must have application for radio ham, so easy to use and user friendly.. Thumbs up!

And. M. Mar 25, 2019     

Nice app but would be better if it had a Digital Voice selection for mode.

Mar. H. Aug 14, 2019     

I like It so far but I can't figure out how to set it to use UTC date and time for the QSO instead of local date and time. Very easy to find my UTC, but why find it if I can't use it?

Dav. M. Apr 24, 2019     

Needed a app to log contacts, this really fits the bill!

Jim. S. May 1, 2021     

Ok logger but does it auto fill? I don't want to fill every blank to log a QSO.

Jai. P. Jan 15, 2020     

Good but but unable to get complete log while on search
