Really, tobaccocellar.com is not good. The design is looks quite outdated to me. As I mentioned earlier, it's not at all mobile-friendly. The public database feature is interesting, though.
Check out the Memento Database app for Android, if you have an Android device. You can download a pipe tobacco cellar template. There's a pipe inventory database template, too. I use the cellar template called "Pipe Tobacco Cellar v1.12, which you can download in Memento as follows: Add LIbrary/Online Catalog/Search for "Tobacco". This is a very flexible tool. I've modified the template that I mentioned to suit my needs. For instance, I added a field for the tobaccoreviews.com average rating. One of my favorite features is the ability to sync with Google Sheets. This provides not only a backup, but insurance against Memento going out of support or your choosing to switch to iOS, for example.
Since I already had a Google Sheets spreadsheet with most of my cellar, here's how I entered much of it in Memento for a quick start.
1) Created a few representative entries directly in Memento.
2) Synced to Google Sheets
3) Went to Google Sheets and opened up the newly synced Tobacco Cellar spreadsheet
4) Copied my entries into the appropriate columns of the new sheet. Note that Memento is pretty flexible in terms of the import. I had entered G. L Pease as "GL Pease" in my original spreadsheet. This imported OK into Memento even though it had "G. L. Pease" in its preset list of manufacturers.
5) Synced again in Memento.
Once the majority has been entered into Memento, it's also nice to use Google Sheets for larger volume edits. For example, Memento tells you the total number of ounces in your cellar, but totals that by adding up the quantity of tobacco, without respect to the unit of measure. So, a 50g tin and a 1.75 ounce tin would display as 51.75 ounces. As a result, I converted all my entries to ounces. This was a fairly quick find and replace in Google Sheets.
It's not perfect, however. The biggest shortcoming is that if you open a tin and you have more than one in your cellar, you need to copy the entry to create the opened tin, then go back to the original entry and reduce the tin count.
