Fulcrum: If you need a managed cloud back end, user management and a support agreement

Free Android GIS data collector that pairs with external RTK GNSS receivers
As of 1 September 2026, SW Maps is free to use. A genuinely free mobile GIS app from a Nepali engineering consultancy that connects to Bluetooth and USB RTK receivers, which is the feature commercial field apps charge a subscription for. Softwr lists it under Maps. SW Maps is made by Softwel (P) Ltd, available on Android.
Overview
SW Maps is an Android application for collecting, displaying and sharing geographic data in the field. Users define point, line and polygon layers with custom attributes including text, numbers, dropdowns, checklists, photos, audio and video, then collect against them offline. It loads basemaps, unlimited geospatial PDF layers and standard vector data, and exports to KMZ, shapefile, GeoJSON, GeoPackage, spreadsheets and CSV. The fact that matters commercially is the GNSS support. SW Maps connects to external RTK GNSS receivers over Bluetooth or USB serial, reads NMEA, applies antenna height and records fix quality per point. That means a survey-grade receiver plus a cheap Android tablet plus a free app produces centimetre-level attributed field data. Commercial equivalents from Esri, Trimble or Juniper charge annual per-user subscriptions for the same capability, and for a team of ten field staff that difference is thousands of pounds a year. It is developed by Softwel, a Kathmandu engineering consultancy, originally for its own water supply and infrastructure projects, and is distributed free with no advertising. The trade-off is what free from a small consultancy means: Android only, no iOS, no managed cloud back end, no contractual support and no roadmap commitment. Organisations that need auditability, user management and a support agreement should treat SW Maps as a capable field tool inside a workflow they manage themselves, not as a platform.
The honest half
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about SW Maps.
Cross-shopped
Each pairing was judged by two reviewers asking whether a buyer would genuinely weigh the two against each other. The ones that failed were deleted rather than published.

Answered, with sources
Each answer names the page it came from, so you can check it rather than take our word for it.
Yes. It is free with no advertising and no paid tier. There is no subscription and no feature paywall.
Yes, over Bluetooth or USB serial, with NTRIP correction support, antenna height and per-point fix quality recording.
No. Android only.
Softwel, an engineering consultancy in Kathmandu, Nepal, which built it for its own infrastructure projects.
Not contractually. There is no commercial support agreement, which is the main reason organisations with compliance obligations choose a paid alternative.

Softwr does not host reviews and shows no star rating for SW Maps, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it. Tell us if any of it is wrong.
