Mobile app

To use the app you need an account on the Trap.NZ website which is a member of an existing project. The Trap.NZ app works with the TrapNZ website and allows you to record trapping data on your phone. With it, you can plot traps, bait stations, monitoring stations, and bird count locations. You can also add records to installations (traps, stations and locations) when you are out in the field.

App: Getting started

The Trap.NZ app works with the TrapNZ website and allows you to record trapping data on your phone.  With it, you can plot traps, bait stations, monitoring stations, and bird count locations. You can also add records to installations (traps, stations and locations) when you are out in the field.

The app will show you a map of your project area and works offline (when you are out of cell phone or WiFi coverage).  Records are stored and synced automatically whenever there is a data connection available.

App: Logging in

To use the app you need an account on the Trap.NZ website which is a member of an existing project.

If you don’t have an account, go to the Create new account page.  After you have created an account and logged into the website, you can then create your own trapping project, or request to join other projects.

As soon as you have an account which belongs to a project, you can use the app. The main app menu allows you to select a project, and from there you can begin adding data or changing the app settings.

Click the edit button on the first installation you want to service to start adding records. As you save each record, the next installation's record form will load, making walking a line easier.

The app's Project Settings menu can be accessed from the app menu.

Synchronise Project 

Normally, changes to projects are synced automatically. For example - if someone else adds a trap or bait station to a project, this will become visible in the app within a few minutes. 

Clicking this button will immediately flush the project cache and force a refresh of the entire project.

Tile management

Refresh map tiles

This will re-download the map tiles for the project. This is usually not necessary, but if your map has gaps, this button may help download them.

Max tile set size

This is the number of megabytes dedicated to the map tile set of this project. 

If you need better resolution on the map you can increase this value at the cost of space on your device. Equally, f you are concerned about the lack of space on your device and don't need the map detail, you can decrease this value.

If in doubt leave it at the default (100).

The Hi-Res zoom limit indicates which zoom level the tiles will start to degrade at. The maximum zoom is 21, so if yours says 13 / 21, the map will get increasingly fuzzy as you zoom beyond zoom level 13.

Enables the satellite base map.

Enables the topographic base map.

Enables the street's base map.

Enable layer options

Layer options provide additional detail to the map.

Parcel Boundaries
Provides a map of the land, road, and other parcel boundaries, which is great for contractors and volunteers on private and public land. These are displayed as a black outline overlaid on top of the current base map.

Shows labels for regions, cities, towns, and street names on top of the current base map.

Auto map centering
Automatically move the map to keep your location in the centre of the screen.

Display installation labels
This will turn labels on or off for your traps, bait stations, and monitoring sites. The labels only show when you are zoomed in. 

Display line labels
This will turn labels on or off for your lines in the map view.

Hi-res tiles on demand
This setting will automatically download higher detail maps when you have an internet connection available (mobile or WiFi). Ideal for urban projects where network coverage is available and higher accuracy is required. These are only stored temporarily on your device and won't be available offline. To save high-detail map tiles for offline use, change the Max tile set size in Project settings.

Enable advanced record fields
Enables advanced record fields such as Sex and Life stage

Display installation details
Installations can have notes entered against them on the website. Notes can be used to record hazards or access details. Notes (including some other information like coordinates and when the last record was added) can be automatically displayed when adding a record. Check this box to automatically display the installation notes.

The name is used to identify records you make. Defaults to your name on Trap.NZ.





settings general (3).png

Accessibility Mode
Where possible and appropriate display user-friendly labels on buttons, larger fonts, etc

Smart Lines
Smart lines will automatically pull other installations into an existing line if it is within a metre of another line member

If switched off, only installations that are at the exact coordinates of line members will be pulled in.

Help popups will appear in some situations - you can disable these once you know your way around the app.

Auto-sync incoming changes
By default, this setting is enabled, and the project will automatically update when project changes occur. This can affect performance on large projects with multiple trappers working simultaneously - in which case we recommend disabling this setting. 

When disabled, a cloud download button will appear in the menu bar when changes are detected. Press this to manually sync the changes.

After this period, installations are highlighted in red to indicate they need attention. Defaults to 90 days.
