Fine on phone, bad on ipad

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).

Great but a suggestion

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

Works well with SparkFun RTK Torch over BLE

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)

NTRIP broken on version 1.2.1

NTRIP is broken on latest version and without NTRIP this app has very little use.

Fixed Feb 11th!! NTRIP in USA broke on Feb 7, 2025

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
