- Format
- Multimodal — receipt photographs and e-receipt records at capture; parsed tabular basket/line-item records plus structured survey and demographic responses after processing
- Volume
- Bounded estimate: ~50K core panelists × ~8 receipts/month × ~10 line items ≈ 4M line-item rows/month, so roughly 40-50M rows/year at basket depth, plus a parallel e-receipt stream from linked email/Amazon accounts and a multi-year longitudinal spine per household. Request the current validated-receipt count and mean household tenure.
- Users
- ~50,000 active panel participants (figure reported in trade coverage of the Checkout Tracking methodology). Download counts are far higher — Google Play shows 1M+ installs on one tracker and ~2.74M on another, ~41K Play ratings and ~23K iOS ratings at 4.4★ — but downloads vastly overstate the qualifying panel, because only validated repeat submitters are useful to the panel.

- Growth
- Mature, actively maintained, no longer growing as an independent product — app updated through mid-2026 (v8.9) with a long release history, but the panel has been absorbed into its parent group, and consumer-app revenue is trivial (third-party forecast ~$146/month), confirming it is a subsidized data-collection instrument rather than a commercial app.
- Launched
- 2013-2014 — iOS listing released November 2013; Android package com.receiptpalapp.android released 18 April 2014. Use 2013 as the dataset start. Built originally by a design agency as an NPD Group client project specifically to incentivize receipt submission for research.
