Common questions

Honest answers about how we compare.

Why does Lost Then Found cost money if others have free tiers?

The alternatives that offer a "free" tier typically don't include SMS alerts, and lock the useful features behind a monthly subscription. We charge a one-time fee that covers the hardware and running costs, and that's it. No monthly charges, ever. Over a dog's lifetime it's dramatically cheaper.

What happens if Lost Then Found shuts down?

We've committed to giving owners reasonable notice if we ever shut the service down. The NFC tag itself would just stop working as an alert - it would fall back to a standard contact tag. We keep costs low and have no investors to answer to, so we're not going anywhere.

Why NFC instead of QR?

NFC works with a tap - no camera app, no QR scanner, no fiddling in a stressful situation. Most modern phones tap automatically. QR codes require the finder to open their camera, line it up, and wait. In the moment when someone's just found a lost dog, simpler is better.

What if the finder's phone doesn't support NFC?

NFC is standard on all iPhones since the 6s and nearly all Android phones made in the last five years. If someone's phone genuinely doesn't support it, the tag includes a printed URL they can type in manually as a fallback.

How does the messaging work?

When a finder taps your dog's tag, you get an SMS and email with their GPS location. A chat thread opens on the profile page so you and the finder can communicate directly - no phone numbers shared on either side.
