If you plan to make fewer than 30 contacts, the Field Day app can be free. A la carte, this one application is $8.99, or go whole hog and buy the entire N3FJP suite, every program, with upgrades for $59.99 An incredible value.
If you want something completely free the best alternative I know of is the N1MM+ logger. https://n1mmwp.hamdocs.com/
I used N1MM+ for a few contests and while easy to use, the N3FJP software is just so much easier to set-up. My contesting style will cause W3SOX and AF3I to scream “no” but I typically wake up Saturday, cannot find anything better to do, turn the radio on, hear a contest, realize I can probably make a few Qs then I go looking for the software. By the time that is done, the band has faded out and I didn’t do so well. N3FJP just seems easier to find the right contest software and install it.
While you are at it, the 13 Colonies Special Event is coming (July 1-7, 2022). The N3FJP Amateur Contact Log easily handles that event. After you launch AC Log, be sure to click on View >> 13 Colonies for an enhanced tracking tool developed by Scott, Kimberly, and Chris.
The PA QSO Party is coming as well on October 8 and 9, 2022.
