SW Maps is a free GIS and mobile mapping app for collecting, presenting and sharing geographic information. Whether you are conducting a full scale GNSS survey with high precision instruments, need to collect large amount of location based data using nothing but your phone, or just need to view a few shapefiles with labels over a background map on the go, SW Maps has it all covered. Record points, lines, polygons and even photos and have them displayed over your choice of background map, and attach custom attribute data to any feature. Attribute types include text, numbers, an option from a predefined set of choices, photos, audio clips and videos. Conduct high accuracy GPS surveys using external RTK capable receivers over Bluetooth LE. Draw features on the map by adding markers, and measure distance and area. Reuse the layers and attributes of a previous project for another survey, or create templates and share them with other users. Share the collected data with other users as Geopackages, KMZ or shapefiles, or export them to your device storage. Also share and export recorded data as Spreadsheets or CSV files. All data is recorded and exported in the standard WGS84 Geographic coordinate system (EPSG:4326). Features -Online Base maps: Apple Maps or Open Street Map -Support for multiple mbtiles and KML overlays -Shapefile and Geopackage layers, with attribute categorized styling. View shapefiles in any coordinate system supported by the PROJ.4 library. -Add multiple online WMTS, TMS, XYZ or WMS layers and cache tiles for offline use. -Connect to external GPS receivers using Bluetooth for high accuracy surveying using RTK with built-in NTRIP client. Also record data from external receiver for post processing. -Define multiple number of feature layers, each with a set of custom attributes Feature Types: Point, Line, Polygon Attribute Types:Text, Numeric, Drop down Options, Photos, Audio, Video Save as Template for re-use or sharing -Record GPS tracks, with distance measurement -Label features based on attribute values. -Import feature layers from templates or existing projects. -Share or export collected data as KMZ (with embedded photographs) , shapefiles, GeoJSON, Geopackage (GPKG), XLS/ODS spreadsheets or csv files. -Share templates or projects with other users -Supports use of GTX geoid files. To use custom geoids, prepare a GTX file with offsets in meters from WGS84. This product is made in Nepal and is FREE (no Ads).

Spare sometime to visit this wonderful country and know the Nepali people. ## Key features - Collect points, lines, and polygons - Attach custom attributes (text, photo, audio, video) - High-accuracy GPS surveys with external receivers - Offline map support - Export data in multiple formats (Shapefile, GeoPackage, CSV) - Create and share project templates ## Recent user reviews (10 of 20) All indexed reviews: https://appshunter.io/ios/app/sw-maps/id6444248083/reviews.md ### 5/5 — Love this app but needs a fix *2026-07-28* Unbelievable abilities with this app using Ardusimple RTK stick. However, something has happened that we cannot export the shape files anymore. Just sends blank zip file. Please help. ### 4/5 — No layers on shapefiles after recent update *2026-06-17* When I share project using shapefiles, only photos appear but layers are missing after recent update. Please fix it! ### 3/5 — Direction! *2026-06-07* I can’t see the direction that I go! Just a small red circle that shows my position. Please fix that. ### 3/5 — Non functioning external receiver *2026-05-05* No matter how I try to connect to an external gnss receiver (garmin glo 2 or sky pro). It will not connect and app developer does not respond. ### 3/5 — Fine on phone, bad on ipad *2025-05-25* can’t add layers on my ipad like I can on the phone, limiting usefulness of app. Something is messed up in the interface, there is no “cancel” or “add” buttons on the ipad to add the layer. Seems like it is because the ipad creates a square window the add layer interface pops up in, but the interface is copied from the phone version hence the buttons are never drawn (they are off screen bottom). ### 4/5 — Great but a suggestion *2025-03-21* The stake out function should show compass heading to 2. Decimal Places. N20.15 is not equal to N20.2 it gets rounded too. Surveys use two decimal places ### 3/5 — Works well with SparkFun RTK Torch over BLE *2025-03-02* Working well but needs a key surveyor tool Need to be able to mark a point via GPS and use an application feature to draw a line and add a point a set distance and compass heading away from starting point (iron pin) ### 1/5 — NTRIP broken on version 1.2.1 *2025-02-23* NTRIP is broken on latest version and without NTRIP this app has very little use. ### 4/5 — Fixed Feb 11th!! NTRIP in USA broke on Feb 7, 2025 *2025-02-12* Very timely repair when NTRIP broke Going to test on my SparkFun Torch soon (March 2025) Works great on iPhone, but external GNSS appears latest release broke NTRIP for USA users ### 3/5 — NTrip in USA broke Feb 7, 2025 *2025-02-09* Works great but appears latest release broke NTRIP for USA users ## Frequently asked questions about SW Maps ### What is SW Maps used for?
