Two free samples, no sign-up and no email needed. Try them first, upgrade only if they are useful to you.
Crypto Portfolio Tracker – free sample (.xlsx)
The same formulas as the full Tracker (average cost method, realized and unrealized profit/loss, dashboard totals), limited to 2 coins and 15 transactions, without charts. Works in Excel 2010+, LibreOffice Calc and Google Sheets. No macros, no internet connection; prices are typed in by you.

Telegram anti-spam module – free code (MIT, .zip)
The anti-spam module from our Telegram Group Bot Starter Kit plus a minimal python-telegram-bot v22 bot that deletes links and banned words from non-admins. Includes a README and 20 offline tests. MIT license for this sample only.

Both full versions together
The Tracker + Bot Kit bundle costs $24 instead of $28.
How we tested
The Tracker sample was recalculated in LibreOffice and checked against an independent calculation (no error cells). The anti-spam code passes its tests offline with a mocked Telegram API; it was not tested in a live Telegram group for this sample.
