### 5/5 — Super portable logging S/W

*2026-07-27, version July '26*

Using for 2 weeks now - mainly POTA and it syncs between iPad and iPhone seamlessly.  I export the data to MacLogger DX.  Very impressed

### 5/5 — Best Mobile Logger

*2026-07-25, version July '26*

I’ve tried them all and Ham2k PoLo is the best mobile ham radio logging software around. Sebastián and team have added so many great features while never compromising the simplicity of the logging process, which is why I always come back to this app. Also, their customer support is stellar! 73, W1RMW

### 5/5 — The Best for Portable Loggin

*2026-07-20, version July '26*

This is absolutely the best for portable logging when out and about.  It is much easier to use my cell phone or iPad than bringing a laptop computer.  The only downside of this program is the inability to read the freq. and mode from the radio.  However, I mostly use it for POTA activations as an activator of which I typically run a freq.  Therefore, no need to read the radio.  Hunting POTA stations is super easy with the spots feature.  Just click and everything is updated in the log.  Definitely would recommend this to other POTA operators.

### 5/5 — Best POTA logging software

*2026-07-09, version June '26*

By far the best.

### 1/5 — Ham2K PoLo’s weaknesses are not basic concept or adoption; they are operational maturity issues

*2026-07-08, version June '26*

It is mobile-first, desktop-light, dependent on external services, still changing quickly, still producing active bug reports, and not yet a complete all-in-one radio/logging automation system. For serious field use, the main risks are update regressions, sync confusion, stale offline data, export friction, ADIF duplicate handling, and lack of deep rig/FT8/desktop automation.

### 5/5 — Works great on the Mac too

*2026-03-21, version February '26*

If you are used to Ham2K on the iPhone or iPad, download it on your Mac… works great!

### 5/5 — Absolutely the best choice for POTA

*2026-02-25, version February '26*

This lightweight app is perfect for POTA (or any ?OTA).  It manages all the important aspects of an activation so you can concentrate on making calls. There is an indispensable call stacking feature that makes handling pileups a blast. At the end of the activation all of the pertinent logs are able to exported for importing into your main log, LoTW, and the POTA website.  Hands down the best choice.

### 5/5 — Superb app for logging

*2025-12-20, version October '25*

This is a great app for logging whether it is just general QSOs, or POTA, SOTA etc. I use this for all my activations, I use it to view who has been spotted, and for other qsos. I then export the adif file from this app and upload to QRZ, EQSL, POTA ETC. Great app.

### 5/5 — Love this logging app!

*2025-12-18, version October '25*

If you activate popular schemes such as Bunkers on the Air, POTA etc then this app makes logging QSOs quick and easy! It works as a great logger for a busy session in the shack too. Once set up, caller’s names are displayed almost instantly so you know who you’re having a QSO with. It comes with a built in mapping function as well, so you can plot where all your contacts are visually. Great app and free too, but please support the developers so they can keep making it even better.

### 5/5 — Wow!

*2025-11-09, version September '25*

What a great app! For now this is my one and only logger. When used in landscape mode on an iPhone it even shows an adjustable split screen! Amazing!
