Any suggestions on the best apps or software for keeping track of various reloads? I'm not as much interested in ballistic calculations, pressure calculations, etc. as I am in keeping track of the different batches and loads of ammo I have.

In the past I used to use a simple Excel spreadsheet, and am now using the (free) version of Shooter's Log, which is okay. But as I often spread out the reloading steps over a few days, split batches with different powder/bullet combinations, etc. I'm looking for something a bit more flexible.

Thanks in advance,
