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.

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.

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.
Walk into the green area on the map, point your camera at the property, hold still, capture.
Photos are taken in the app during the visit. There's no option to add old ones from the gallery.

Doing the visits for someone? How it works for the person on site.
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.

NEMZIO Land
A surveyor searches the survey plan at the state survey office. A lawyer traces the title at the land registry. Their signed reports go into the property's record. Fees: $179–$549 per check.
You pay for the app, the record and its storage. The person who visits never pays. Prices in US dollars.
Start with a 3-day free trial on one property, up to 5 photos or videos.
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: registered surveyors and lawyers do that work and sign their own reports.
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.
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.
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.
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 put it to them, and they sign their own reports.
Properties in Nigeria, Ghana and Jamaica. Land checks: Available now in Port Harcourt. Lagos and Abuja coming soon.
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.
Set up a property and invite your person on site in a few minutes. The trial is free.
