The ham radio logbook app for iPhone and Android

Type a callsign, tap Log, and the contact is in your log. QSL World Logbook keeps your whole log on the phone, works without signal, and shows every QSO on a map. It is free to download, and it keeps the same log you use on qslworld.com and in Ham Browser.

Log a QSO in seconds

Callsign, reports, Log. The UTC clock runs, the band follows the frequency and a duplicate is flagged before you save it.

No signal, no problem

Activating a park on a hilltop? Contacts logged offline wait on the phone and go up to qslworld.com when you are back in range.

Confirmations come to you

LoTW, QRZ and eQSL confirmations are brought into your log, so you can see which contacts are confirmed without opening three websites.

Know when they are on

Put a callsign on your watch list and the phone tells you when it is spotted, even with the app closed.

A complete ham radio logbook in your pocket

Everything a radio amateur keeps in a log, and the things a paper log never could: where each contact went, who confirmed it, and who is on the air right now.

Callsign lookup

Enter a call and the name, grid square and country are filled in for you. Search your own log by callsign, name, country or grid.

A log for every activity

Keep separate logbooks for everyday operating, contests, POTA and SOTA activations, each with the fields that activity needs.

QSO map and flight paths

Every station you have worked on one map around your QTH, and an animated path from you to them for each contact.

QSL cards, sent and received

Send your QSL World card to any contact straight from the log, and keep every card that comes back in one album.

Live DX cluster and POTA spots

See who is being spotted as a list or on the globe. Tap a spot and its call, band and mode are ready to log.

Grey line and propagation

The grey line on the globe, solar and propagation figures, and the amateur satellites passing over you.

Grid Rush

The grid squares you have worked become a game: a spinning globe, a score, badges, a world ladder and Recon for every square.

Radio control

Read the frequency and mode from your rig over a Bluetooth CAT adapter, Hamlib rigctld or flrig, so the log always has them right.

One log, everywhere

The app, qslworld.com and Ham Browser share one account and one log. Log on the phone, find it on the computer.

How it works

From the first contact of the day to the last confirmation, this is what a day with the app looks like.

Sign in once, with the account you already have

Use your qslworld.com or Ham Browser account, sign in with Apple or Google, or create an account in the app with your callsign. Your log is waiting for you the moment you are in.

Your station, your details

Your callsign, grid and QTH come along, so every contact is logged from the right place.

Log at the radio, in the field or in the car

The quick-log bar sits under your thumb. Type the call, the reports and tap Log. Pick a spot from the cluster and it is filled in for you. Without signal the contact is kept on the phone and sent later.

UTC, band and duplicates

The time is always UTC, the band is worked out from the frequency, and a repeat contact is caught before it is saved.

Confirmations and QSL cards, without the chasing

Confirmations from LoTW, QRZ and eQSL arrive in your log on their own. Send a QSL card to a contact with one tap and watch the cards other stations send you fill your album.

Your QRZ logbook, kept current

Connect your QRZ logbook and each contact you log is added to it as well.

See where your signal has been

Open the QSO map to see every station you have worked around your QTH, or play a contact's flight path across the globe. Check the grey line and the bands before you call CQ.

Spots on the globe

DX cluster and POTA spots, filtered by band, placed where the stations are.

Turn your grid squares into a game

Grid Rush scores the squares in your log, awards badges as you fill the map, and puts you on a world ladder with other operators. Recon shows what is waiting in every square you have not worked yet.

New square, new points

Work a square you never had and the globe tells you about it.

Questions

What radio amateurs ask before they install it.

Is QSL World Logbook free?

Yes. Downloading it and keeping your log are free, with no limit on contacts. Extras such as the QSO map, QSL cards, LoTW, QRZ and eQSL, Grid Rush and radio control come with an optional plan you can add inside the app whenever you want them.

Does it work without a mobile signal?

Yes. Your whole log is stored on the phone, so you can search it and log new contacts anywhere. Anything logged offline is sent to qslworld.com as soon as the phone is back online.

Is it the same log as qslworld.com and Ham Browser?

Yes. The app, qslworld.com and Ham Browser use one account and one log, so a contact logged on the phone shows up on the computer and the other way round. You can sign in with that account, with Apple or Google, or create a new account in the app.

Can the app upload my contacts to LoTW?

LoTW uploads have to be signed with your TQSL certificate, which lives on your computer, so uploading stays a job for TQSL. The app shows how many contacts are waiting for LoTW and brings the confirmations into your log as they arrive.

Does it work with QRZ and eQSL?

With QSL World Plan, contacts you log can be added to your QRZ logbook as you go, and confirmations from QRZ and eQSL are brought into your log.

Which radios can it control?

With QSL World Pro the app reads the frequency and mode from your radio through a Bluetooth CAT adapter, or over the network from Hamlib rigctld or flrig.

Which phones and tablets does it run on?

iPhone and iPad with iOS 17 or later, and Android phones with Android 8.0 or later.

Which languages is it in?

English, Spanish, Portuguese, Italian, French, German and Japanese.

How do I cancel a plan?

On iPhone and iPad, in your Apple Account settings under Subscriptions. On Android, in Google Play under Payments and subscriptions. Deleting the app does not cancel a plan.

What happens to my data?

Your log is kept in your QSL World account. You can delete your profile from inside the app at any time. The details are in the app's privacy policy.
