Review summary

Reviews consistently highlight strong GNSS capabilities and the app's status as a top iOS GIS, but repeatedly flag connectivity problems with external GNSS receivers, broken NTRIP functionality, and notable UI/UX issues (especially on iPad) that hamper usability.

Pros

GNSS integration enables precise surveying with external receivers (Bluetooth/BLE).
Widely regarded as one of the best GIS apps for iOS.
BLE GNSS support exists and has been noted as improved.

Cons

Cannot connect to external GNSS receivers and lacks auto-reconnect to Bluetooth GNSS devices.
NTRIP client is broken or unreliable across versions, sometimes limited to wifi.
Significant UI/UX issues, including iPad-specific interface bugs (missing add/cancel buttons) and non-working side menus.

2026-07-28	wi*****	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.

2026-05-05	tu*****	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.

2025-05-25	ho*****	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).

2025-03-21	Ch*****	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

2025-02-09	XY*****	This is (was) a great app. The update from a few days ago isn’t working with NTrip so I can’t get the full accuracy out of my instrument.

2024-12-02	ni*****	The app is free and enables precise surveying using GNSS receivers. It has many rough edges that make for an unpleasant and slow experience though. The biggest pain point is the inability to auto reconnect to Bluetooth GNSS receivers or to NTRIP servers, followed by the inability to store multiple NTRIP credentials or even to support copying and pasting into the NTRIP configuration fields.
