Ham Clock

About this app

HamClock is targeted for portable amateur radio operators.
It displays time/date and user notes related to various portable locations on a single screen:
- Local date / time
- GMT date / time
- User notes
- Reminder to transmit callsign every 10 minutes, as required in some countries.

Note can be entered in up to four fields. Use it to record location name, QTH locator, callsign, activation details for SOTA, WCA, WFF or other activities, event info etc.

Multiple notes can be entered and saved for later use.
Note view is scrolled to show longer texts
Hide local clock, leaving even more room for notes

- Large font and contrast for readability in bright daylight.
- Light / dark color scheme
- Configurable date format
- Configurable display timeout.
- Optional popup every 10 minutes to remind you to transmit your callsign.
- Optional ringtone played along with the visual reminder. If you don't want audio alert, select "silent" or "none" ringtone.

- Share note content as a simple text file, formatted as JSONArray (string). Extension is .hctxt (HamClockTxt) but can be edited in any text editor.
Sharing works best via Gmail or GoogleDrive. With Gmail, open/receive directly from an attachment (no need to download the attachment first). If proper JSONArray file format is detected, "save or discard note" is offered.

Sharing via Bluetooth is less reliable on different devices, because android versions and phone vendors vary in trusted file types for BT transfers, and in permissions needed to access bluetooth storage space (received files).
Sharing via other applications is not tested, and it may or may not work.

Ratings and reviews

So far so good. Nice and simple and easy to read in the field. I do have a couple items for the "wish list" 1) Have a second timer that would repeater at what ever timer interval the user selects. I am planning on using this app while doing POTA activations and it would be nice to have a repeatable timer that I could set for say 25 minutes to remind me to respot my activation on the POTA Spotting web page. 2) Be able to select different colors for the text of each of the screen frames. Thanks for a nice app..

The app is great by itself but it's not quite what I'm looking for. I need a quick utc reference so what I really need is a widget. There should be an option to easily create a widget within the android sdk so of you could do that sometime I'd be willing to pay for the upgrade.

I'll give it points for displaying both local and UTC times together, but there REALLY ought to be an option for displaying seconds as well as minutes. Seems rather pointless without the seconds.

*4.03*
**Sharing notes: fixed crash on Android 7+ thanks to firebase crash analytics

- Importing notes works best from G Drive or Gmail (don't save attachment)
Due to low standardization, others give different results per device, android version etc. Your mileage _will_ vary

- App imports note as plaintext if JSON format fails
- Types pdf, jpg, gif..silently discarded

*4.02*
- Very important fixes + firebase crash analytics to catch a rare problem (occasionally needs internet perm.)
