Popl is a slick way to swap contact info. FieldStacker gives you a free card that shares by tap, QR, or text — then captures the contact, ranks it with AI, and drops it into a full door-to-door sales CRM you can actually close on.
Free card forever · full app flat from $25/mo · 30-day free trial · no credit card
A contact-share card is a great first touch. It's memorable, it's paperless, and it gets your info onto someone's phone in a second. But for a sales rep it stops right when the real work starts: it doesn't tell you which houses you've already hit, doesn't route your day, and doesn't track a dollar of what you earn. So you end up with a card app and a canvassing tool and a spreadsheet.
FieldStacker puts them together. The card is free forever. The rest — the map you knock, the quotes you write, the commission and taxes you track — is one flat, month-to-month price with a 30-day free trial and no credit card to start.
Where a contact-share app and a full sales CRM overlap — and where they don't.

The card is a complete free product on its own — share it, build your network, never pay a cent. And it's included in every paid FieldStacker plan, so upgrading only ever adds the map and the money on top.
For a sales rep, yes. Popl is a polished contact-sharing app built around NFC taps and QR codes — great for networking. FieldStacker gives you a free digital card that shares the same way (tap, QR, email), then goes past networking: every contact is captured and pinned on a map, AI ranks your warmest leads, and the card is one feature of a full door-to-door sales CRM. If you just want to swap contact info, Popl is purpose-built for that. If you want the card plus a pipeline you can actually work, FieldStacker is the bigger stack.
The FieldStacker card is free forever — no credit card. Popl offers a free basic tier and charges for team, analytics, and CRM-style features; check popl.co for their current plans. With FieldStacker, the analytics, notifications, unlimited sharing, reviews, and the contact network are all free, and the full sales CRM is a flat month-to-month price only if you choose to upgrade.
FieldStacker is built for door-to-door and field sales, where reps share on the spot by showing a QR to scan or texting a link — no accessory to carry or forget. You get the same instant "save me to your phone" moment as an NFC tap, plus an open notification and automatic contact capture. If a physical NFC product is the main thing you want, Popl specializes in that hardware.
The whole sales side. A knock map with recently-sold and new-mover leads, color-coded custom dispositions, traceable territories, GPS-verified team knocks, prime-time analytics, AI objection coaching, and a leaderboard — plus per-deal commission, chargebacks, auto-mileage at the IRS rate, and a quarterly tax set-aside. Popl helps you share your info; FieldStacker helps you find, close, and get paid on the people you meet.
Yes. Sign up for the free card, share it, and let your network build itself — no obligation to ever upgrade. And unlike a standalone card app, your contacts are already sitting in a real CRM: the day you want to knock a route or quote at the door, everything is there with nothing to re-enter.
Always. The card is free on its own and built into every paid FieldStacker plan. Upgrading adds the map, quoting, and financials on top — it never removes the card or your network.
Share like Popl for free, and keep every contact in a CRM you can actually knock, quote, and get paid on.
