From price change to push
Built to move quickly without skipping the evidence.
A dramatic percentage alone is not enough. DropSignal is designed to verify the product, seller, price, and availability before an offer earns an alert.
We check the signal
The system is designed to confirm the exact product, retailer-direct seller, public price, availability, and relevant history.
See what qualified
Released alerts can show the evidence behind the classification, confidence, and most recent verification time.

Price intelligence you can inspect
The evidence is part of the alert.
DropSignal is being built to distinguish unusually strong legitimate deals from possible pricing errors—and to suppress offers when important checks disagree.
- ✓Current public price and credible reference price
- ✓Previous price, historical average, and historical low
- ✓Direct-retailer comparisons where available
- ✓Confidence, lifecycle, and last-verified timestamp
- ✓Nationwide shipping or local-store context
!
Accuracy earns urgency. If independent checks disagree, the signal should wait—not reach your lock screen.

Timing begins when DropSignal first observes and qualifies an offer—not when an unseen retailer-side change occurs. Source cadence, verification, networks, push providers, and the user’s device can affect delivery. Prices and plans are intended launch offerings.
Coverage, earned source by source
Built for the stores people already shop.
Our planned retailer radar spans national, specialty, warehouse, home-improvement, and apparel destinations. Each one must independently pass data-rights, accuracy, and freshness gates before activation.

Planned coverage does not imply affiliation, endorsement, current monitoring, or live integration.
Clear expectations
A signal is information—not a promise.
Public prices only
Personalized, session-specific, account-specific, and credit-card-specific offers are excluded.
No purchase automation
DropSignal does not place orders, enter payment details, or intentionally reserve inventory.
Honest lifecycle
Automated revalidation can mark a signal Price changed, Out of stock, or Expired.
Retailers stay in control
The retailer controls price, eligibility, order acceptance, cancellation, returns, and fulfillment.
Straight answers
Good signals begin with clear expectations.

developer@dropsignal.ioIs DropSignal live today?
Not yet. The native iOS and Android apps and their production services are in development. This site does not claim a live retailer integration or public app-store release.
What is a possible pricing error?
It is an extreme public-price anomaly that passed DropSignal’s minimum publication checks but may have been posted unintentionally. Retailers can correct a price or cancel an order.
What does verified mean?
DropSignal independently observed the public offer and it passed internal checks for product identity, retailer-direct seller status, price, availability, and supporting evidence. Verification does not guarantee fulfillment.
Does DropSignal earn money when I shop?
No. The planned business model is subscriptions only—without ads, affiliate links, sponsored placement, or retailer purchase commissions.
Will every planned retailer be available at launch?
Not necessarily. Each source will go live only after its access, data rights, freshness, accuracy, and operational controls pass review. Coverage will stay explicit.
Can I receive nearby deals?
Yes. You can optionally add a ZIP code and choose a 10, 25, 50, or 100-mile radius. Leaving it blank keeps your radar focused on nationwide online offers.
