The details
Someone you trust goes to the property. The app guides them, and every photo keeps where and when it was taken. You get a dated record of the visit.
Location checked · 10:16 WAT
Recording of the NEMZIO interface, with sample data.
How a visit works
No checklist and no training. The person on site follows one instruction at a time, and the visit asks for the same views every time so visits compare.
Your brother, a caretaker or the site supervisor. The app is free for them, finds their location and points the way.
No spot to find and no dot to line up. Near the property, the phone says so and the camera opens by itself.
One instruction at a time. On a repeat visit, a small picture shows the view to match.
When the view is good, the corners turn green and they tap the button. Photos are taken in the app during the visit, never added from the gallery.
Each view is taken the same way until the visit is complete. With weak signal, the phone sends it later.
Doing the visits for someone? How it works for the person on site.
Walk toward the property. Once you're near, the camera opens by itself: point it at the property and, when the view is good, take the photo.
Walk: drag yourself along the road, tap the map, or select yourself and use the arrow keys (Shift walks further).
Finding your location...
No button to press here: the phone works out when you're near the property.
Complete the demo above and your sample visit record will appear here.
The record
Every visit closes into one dated record. This one answers a contractor who said the roof was going up.

You're in Dallas, London or Toronto, and the site reaches you as a photo in a chat. A photo doesn't say when it was taken, where the phone was, or what was left out.
Roofing has started. The roof timbers are up 👍 Please send the next payment.

Roof line from the front: wall tops open, nothing fixed on top. No roof timbers or sheets.
The claim, against this visit: Not supported(automated)
A relative, a caretaker or the site supervisor does the visit with the free app. You see what they captured, where and when, wherever you are.

The person you invite uses the app free, one instruction at a time.

Each visit repeats the same views, so one visit compares with the last.

The record arrives with where and when, in your time and the property's.
Sample properties
Three made-up properties, each with a full visit record: the map of where every capture was taken, the checks, the claim tested and the history. Every page is labelled as a sample.
SampleObio/Akpor, Port Harcourt
An owner in Dallas is building in Port Harcourt. The contractor says roofing has started; a guided visit shows what the site shows.
Eliozu, Port Harcourt
A plot bought from abroad. Before paying the agent, the owner asks for a photo at each corner beacon of the survey plan.
SampleAdenta, Accra
A walled plot held for later. A caretaker opens the gate every few weeks; the owner wants to know the wall is whole and nothing has been built.
Each visit is added as a new entry, in order. Earlier visits aren't changed, so the record of the house going up stays as it was seen.

The sample house at each visit, with the construction milestone it reached (an automated estimate, never a percentage). A real history keeps each visit's photos, taken from the same views.
A record shows what was captured, where and when. It doesn't establish who owns the land, whether a building is sound, or whether anyone should be paid. Phone location is good to a few metres, not survey grade.
No check makes manipulation impossible. Guided visits make it harder, and every record says what its checks found, including anything that didn't pass.
Everything a record doesn't establishSomeone 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 are different: they are searches of the records, which NEMZIO arranges for you.
Follow one instruction at a time. The app finds their location and says to walk toward the property; when they're near, the camera opens by itself, they point it at the property and, when the view is good, tap to take the photo. It tells them when the visit is complete. No spot to find, no checklist to learn, no settings.
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 1 property with 5 GB of evidence storage, Watch 3 properties with 15 GB, and Watch 5 5 properties with 25 GB. There is no separate charge per normal guided visit.
7 days of Build free, with everything Build includes except automated checks and document reading, which start once you pay. A card is needed to start; nothing is charged today. After 7 days, Build is $14.99/month unless you cancel before the trial ends. Cancel any time in Account. When a trial ends without a plan, your records stay viewable and exportable, and new visits pause until you choose one.
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.
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.
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.
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.
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.
The property's, with the zone named (for example 10:16 WAT). The app also shows your own time alongside.
No. A record shows what was captured, where and when. Ownership is a legal question for a lawyer and a surveyor. Our land checks search the survey records and title history and report what they found; they don't guarantee title.
Properties in Nigeria, Ghana and Jamaica. Land checks: Available now in Port Harcourt. Lagos and Abuja coming soon.
Closing makes it read-only: its records, visits and films are kept and can be exported. A closed or paused property keeps its place in your plan for 30 days, then the place frees, so swapping properties doesn't add visits.
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.
