Store description excerpt
Reckoner tracks Bitcoin addresses you scan or paste in, and values them honestly. Most trackers stop at the spot price. Reckoner goes further: apply your own discount, liquidity haircut, and realization percentages, and see the adjusted value alongside the market value. The assumptions are yours. Reckoner just does the arithmetic and shows its working. READ-ONLY BY CONSTRUCTION No private keys. No seed phrases. No signing, sending, or receiving. Reckoner can read the chain; it cannot move anything on it. There is no account and no login. WHAT IT DOES • Watch any number of public Bitcoin addresses • Add an address by scanning its QR code • Legacy, SegWit, and Taproot addresses, validated before they are saved • Balance and fiat value per address, plus combined totals • EUR, USD, or GBP • Manual refresh, optional auto-refresh, and a clear last-updated time • Filter and sort your addresses • Import and export your list as JSON • Light and dark themes ANALYTICS THAT EXPLAIN THEMSELVES • Portfolio composition: what each address contributes • Market vs adjusted: what your assumptions cost • Valuation waterfall: market value, then discount, haircut, and realization applied in turn, with running totals HONEST ABOUT PRIVACY: Your watchlist is stored only on your device. There is no server behind this app. Balances and prices come from mempool.space, which means the addresses you watch are sent to that provider as ordinary API requests. If you run your own mempool instance, point Reckoner at it in Settings. The camera is used only to read a QR code. No image is stored, and none leaves your device. Reckoner offers no investment advice and makes no price predictions. The percentages are your inputs, not our recommendations.
