A2Plus vs GPX Builder
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
A2Plus
This utility app measures land area, perimeter, and distance with high accuracy. It offers multiple input methods including GPS and manual entry, and supports various units of measurement. Export your plans in KML or DXF formats for use in other software.
- Land area, perimeter, and distance measurement
- GPS and manual point input
- Multiple units of measurement
- KML and DXF export formats
- Archiving and editing of plans
- French land registry overlay

A2+ is an application dedicated to the measurement of land area, perimeter and distance. The moderate grounds can be situated all over the world. A2+ can measure and display the surface and the perimeter of several land on the same plan with intermediate distances. The measurement can be displayed in feet, Inch, Yard or Feet. The application displays the French land registry superimposed on the map. Thus, the measurement accuracy of the plots is greatly improved (useful for a geometrician). A2+ can save plans, edit them and export them via e-mail with the format "KML" (for use with software like Google Earth, Google Maps, World Wind, Sketchup ...) and "DXF" (AutoCAD). The application allows you to import KML files and view fully customizable and cumulative WMS layers. Multilingual: English, French, German, Spanish, Italian, Portuguese, Japanese. A2+ has 4 ways of functioning: - GPS: The user is located on the field. He then confirms a succession of points describing at best the ground thanks to the position supplied by the GPS. - GPS AUTO : The user is located on the field. The application automatically takes the points with a regular time interval. Just move yourself along the ground so that its outline is drawn. The time interval is adjustable from 5 to 120 seconds. The automatic mode can be stopped and restarted at any time. - Manual: the user seizes points manually without moving by finding a way on the map. - Mixed: the user is on the ground and seizes points via the GPS, then can add it manually (for difficult access for example). The calculation of the surface is effected and displayed at each input. The result can be stated in m2 square feet, square yard, are, ha. Features : - Automatic recording of points with a regular time interval. - Measurement of several surfaces on the same plane. - Measure of cumulative distance. - Viewing the perimeter and intermediate distances. - Viewing a compass and altitude for better geolocation. - Points Informations: At any time, the user can know the seized coordinates of the seized points - Movement of the seized points: Every seized point can be moved with the finger to adjust its position. - Deleting a point: A point can be deleted individually. - Manually inserting a new point between two existing points: You can insert a new point between two existing points to refine the tracing of the plan. - Ability to manually enter the coordinates of a point. - Display of the surface: The surface is calculated and shown in every new seized point. - Archiving of the measures: Every moderate ground can be archived with a personalized name. Every archive can be opened again and then again be edited. - GPS reception indicator. - GPS Information: The button "information" allows to show the information of localization of the GPS. - Export plans to KML and DXF format : To export a plan with KML and DXF format, you must go to the backup list and press the icon 'email'. A2+ adds, in the e-mail, the plan attached. You simply write the recipient and send the message. - Import KML file. - Fully customizable and cumulative WMS layer visualization. - Function "undo" and "redo" to undo or redo the last action performed. - Search address to center the map. - Several options of measures are available: Unit of measure: meter, inch, feet and yards. Unity of measure of the surface: m2 square feet, square yard, are, ha. Type of map: Map, Satellite, Hybrid (map + satellite). Other map : OSM, MapBox, Google Map. Custom WMS layers (cumulative). Accuracy in GPS mode: 100m, 10m, 5m. This option allows to forbid the seizure of a point if the precision of the GPS is lower than the instruction. Possibility to display the French Land registry with overlay on the map.
GPX Builder
This utility app allows developers to simulate and record real-world GPS location data for testing purposes. Adjust location settings for accuracy and battery life, then export data as GPX or GeoJSON files. Includes carrier and connectivity data for comprehensive testing.
- Simulate GPS location data

*Continued use of GPS running in the background can dramatically decrease battery life. Developing apps that require location services can be a challenge when the data you receive in the simulator is so much different than what a device receives in the real world. Are your location settings battery friendly enough to solve the problem you are working on or could you do with a little less accuracy? GPX Builder allows you to adjust the settings of the location services to match your project, then record real location data as you create your own test routes for your simulator. You can name each route and email the GPX data back to your development team. We now include carrier and connectivity data so you can generate GPX or GeoJSON files with real world data for unreliable connectivity. We hope this will help you to understand your user's experience better so you can create amazing features. You can export your location data as a GPX file or in GeoJSON format. Points are recorded at a rate of one per second to match the playback speed of the iOS Simulator and give more realistic results when simulating location data. You can still record raw data only by choosing that option in the settings.

Verdict
The clearest difference is price: GPX Builder at Free against A2Plus's $20.99. GPX Builder also leads on ratings volume (4 vs 1) and iOS requirement (15.5 vs 26.0). A2Plus's advantage is rating (5.0 vs 3.8) and ads (none vs shown). On update cadence, in-app purchases and device support there is nothing between them.
