For family abroad with property back home

See what's on your property back home.

Someone you trust visits. The app walks them into the right area before the camera opens, and every photo keeps where and when it was taken. You get a dated record, checked as soon as it arrives.

An illustrated sample visit: the person on site walks along the road, through the gate and into the green area on the plot. The phone says “You're in the right area.”, then “Hold still.”, then “Got it.” The photo appears in the visit record: Where: Likely inside: 5 m from the edge · GPS ±5 m. When: During the visit · received 3 s later. Sample record. Illustrative data: not a real property, customer or person.
  • Taken in the app

    During the visit, never picked from a phone's gallery.

  • Where and when

    Each capture's place and time, with the reading's margin of error.

  • Checked on arrival

    Every visit shows what the checks found, including anything that didn't pass.

  • Kept as it was

    Evidence isn't changed after a visit closes, and a shared record shows whether it has changed since.

01Why

You left home. Your land didn't.

From Dallas, London or Toronto, what you know about the site comes from the people you pay, usually as a photo in a chat. A photo doesn't say when it was taken, where the phone was, or what was left out of the frame.

02Try it

Your turn: be the person on site.

Walk the blue dot into the green area. In the app, the camera opens by itself once the person on site is in the right area. Then take the photo and see what the record keeps.

Drag the dot, tap the map, or select the dot and use the arrow keys (Shift walks further).

Walk to the green area. 6 m to the green area.

Your demo record

Demo · nothing is sent or saved

Photos you take appear here, each with when and where it was taken and a fingerprint of the capture.

This demo runs only in your browser. The plot is made up and the position is where you put the dot, not GPS. In a real visit the phone's position has a margin of error of a few metres, which the record shows; every capture is checked again when it arrives; each file's fingerprint is kept when it arrives, and a shared record's page checks its fingerprint every time it's opened.

03How

A guided visit, one step at a time.

Instead of collecting whatever photos someone chooses to take, NEMZIO directs the person on site through the property and asks for the views that visit needs.

  • One instruction at a time. Walk into the green area on the map, point your camera at the property, hold still, capture. No checklist, no training.
  • Reference views, plus views for this visit. The same reference views every time, so visits compare side by side, plus views chosen for your property and the question you asked.
  • Checked on arrival. Location, timing, coverage and integrity are checked as soon as evidence arrives, and the record shows each result with its uncertainty, including anything that didn't pass.
  1. 01Walk

    The map shows the property and a big green area. Walk into it: there's no exact spot to find.

  2. 02Arrive

    A short vibration says you're there. The map gives way to the camera by itself.

  3. 03Frame and hold

    Point your camera at the property. When it's framed, the corners turn green: hold still. On a repeat visit, a small picture shows the previous view.

  4. 04Capture

    Got it. The next view follows, or the map comes back for the next green area. With no signal, the phone sends the visit later.

However far away you are, the site is one visit away.

04What you receive

A visit record, not a photo album.

Every visit closes into a dated record: where and when it was captured and how much of the property was likely in view. For construction on a paid plan, it also shows what changed since the last visit and how the visit compares with what you were told (automated).

None of this visit's 7 views of the walls and the roof line show roof timbers or sheets, so this visit doesn't show roofing having started.

Visit evidence isn't changed after a visit closes; each new visit or request is added as a new entry. A shared record carries a fingerprint of its stored results and of each file's fingerprint recorded on arrival, and the shared page checks it every time it's opened.
05Checks

Harder to fake than a photo in a chat.

No system makes manipulation impossible. Guided visits and checks make it harder, and every record shows what the checks found, with its uncertainty.

  1. 01
    Where
    Was the evidence captured at the property?

    Each capture's location is compared with your boundary, together with how precise that reading was (on the free trial, the first 2 captures).

    You seeInside · Likely inside · Boundary uncertain · Outside (close to the boundary) · Outside · Inconclusive

    LimitPhone positioning is accurate to a few metres, not survey grade.

  2. 02
    When
    Was it captured during this visit?

    Each capture shows when it was taken and when NEMZIO received it, in the property's time zone.

    You seeDuring the visit · Captured without signal, received later

    LimitWhere timing is less certain, the record says so.

  3. 03
    Coverage
    Did the visit document the property?

    Visits are guided around the property. The record estimates which sides were in view and names any gaps.

    You seeComplete · Incomplete (with the gaps named)

    LimitA record shows what the camera saw, not what was kept out of view.

  4. 04
    Integrity
    Is there any sign the evidence isn't reliable?

    Integrity checks look for indicators that evidence may not be new, may not be from this visit, or may have been altered. We describe what they found, not how they work.

    You seeNo inconsistency detected · Indicators detected · Inconclusive · Not checked

    LimitChecks look for indicators. They can't make manipulation impossible, and we never claim they do.

  5. 05
    Change
    What changed since the last visit?

    For construction projects on a paid plan, comparable views are compared visit to visit: what appeared, what is no longer visible, and the milestone reached (automated, and labelled).

    You seeVisible changes · Not visible from today's views · Milestone

    LimitNot visible is not the same as gone: materials may have been used or moved.

Integrity checks look for indicators that evidence may not be reliable. We describe what they found, not how they work.

For the person on site

Your brother, caretaker or contractor can do it. The app is free for them.

You send an invite code. They open the app at the property and follow the instructions. It keeps working with weak signal. By default they see only what they need for the visit; you decide whether they see anything more. If the person capturing is the one whose work is being checked, the record shows what they captured, not what they left out.

How it works for them →
06Limits

What a record can establish, and what it can't.

We'd rather tell you the limits than overstate the evidence. No system makes manipulation impossible; guided visits and checks make it harder, and the record shows its own uncertainty.

A record can show
  • Where and when each capture was made, with the precision of the reading
  • Which sides of the property the visit likely had in view, and which it didn't
  • When each capture was taken during the visit, and when it reached NEMZIO
  • What changed between visits, from comparable views (construction, paid plans)
  • Whether the stored record has changed since it was shared
It doesn't establish
  • Legal title or ownership of land or a building
  • Survey-grade location or boundaries (phone location can be off by several metres)
  • That a structure is safe, sound or built to code
  • Compliance with planning, building or other regulations
  • That a contractor or anyone else is honest, or that work was paid for or authorised
  • That a payment should be made or was authorised
  • That manipulation is impossible: NEMZIO's checks make it hard and say when something doesn't add up, but no system can rule it out entirely
07Cost

Pay for the checks and the record.

The person who visits is someone you invite, and they never pay. Prices are in US dollars.

Questions

Before you start.

Who goes to the site?

Someone you choose and invite: a relative, a caretaker, a foreman or your site supervisor. They use the app free, and see only what you allow. NEMZIO doesn't supply, vet or pay them; any arrangement for their time is between you and them. Land checks will be different: registered surveyors and lawyers do that work, once our partners are confirmed.

What does the person on site actually do?

Open the app at the property and follow one instruction at a time: walk into the green area on the map, point the camera at the property, hold still, capture. The app tells them when it's done. No checklist to learn, no settings.

What does the subscription pay for?

The app, the checks on every visit, storage of your records and, on paid plans, alerts and automated observations. It doesn't include anyone's time on site. Build covers up to 3 properties and Watch up to 10, with no set limit on visits or photos for normal use (fair use applies; see the Terms).

What's free?

A 3-day free trial on one property, with up to 5 photos or videos in total; location is checked on the first 2. When the trial ends, your records stay viewable and exportable, and new visits pause until you choose a plan.

Can't they just send old photos?

Evidence is captured in the NEMZIO app during the visit; the app has no option to attach gallery photos. Every visit is checked for indicators that evidence may not be new or from this visit, and the record shows what the checks found. No check is a guarantee, and we don't claim one.

What if they only photograph the good parts?

Visits are guided around the property, step by step, rather than left to the person holding the phone. The record estimates which sides were in view and which weren't, so a skipped side shows as Incomplete. If the person capturing is the one whose work is being checked, the record shows what they captured, not what they left out.

What does "Checks passed" mean?

That every check which ran found no issue and the visit covered what it needed to. It's evidence about the visit: where, when and how it was captured. It isn't a verdict on the contractor, the quality of the work or who owns the land, and it never tells you whether to pay.

What can the person on site see?

By default, only the instructions for the visit and a confirmation when it's sent. You decide whether they can see anything more, such as findings you choose to share.

What if there's no signal on site?

The visit carries on and the evidence is saved on the phone, then sent when the signal returns. The record shows when each capture was made and when we received it.

Whose time zone are the times in?

The property's, with the zone named (for example 10:16 WAT). The app also shows your own time alongside.

Does a record prove I own the land?

No. A record shows what was captured, where and when. Ownership is a legal question for a lawyer and a surveyor; our land checks will put it to them, and they sign their own reports.

Where does it work?

Properties in Nigeria, Ghana and Jamaica. Coming soon: land checks open when our partner surveyors and lawyers are confirmed, starting in Port Harcourt, with Lagos and Abuja later.

How do I pay, and can I stop?

By card. Build and Watch are monthly or yearly and can be cancelled at any time; you keep the plan until the end of the period you paid for. After that, your records stay viewable and exportable, and new visits pause until you choose a plan again.

Don't wait for your next trip home to find out.

Set up a property and invite your person on site in a few minutes. The trial is free.
