## What is VuSitu?

Connect the VuSitu mobile app to In-Situ Inc. water monitoring instruments and telemetry to easily view, manage and share water quality and quantity data. Use any Bluetooth-enabled mobile device to configure, calibrate and deploy your instruments, view live readings, and set up logs. Log in to your HydroVu account for secure data storage and sharing.

A user-friendly walkthrough makes it easy to set up log files of all types, even with delayed starts or offset entry. View real-time data on multiple water quality parameters, run low-flow sampling events from your phone, and quickly share your data with colleagues via HydroVu.

The VuSitu mobile app makes it easy to:

• Interface with In-Situ Inc. instruments
• Configure VuLink telemetry devices
• Gather real-time water quality and water level data
• Create logs and manage log data for all supported instruments
• Open data files in Excel or parse into other systems
• Securely store all data files in the cloud
• Calibrate your instruments
• Use instant graphing to determine when to start and stop readings
• Receive firmware updates for connected instruments and communication devices with embedded automatic updates or custom downloaded files
• View data for conductivity, optical dissolved oxygen (DO), ORP, pH, turbidity, water level/pressure, temperature, ammonium, nitrate, chloride sensors, chlorophyll a, phycocyanin (BGA-PC), phycoerythrin (BGA-PE), FDOM, crude oil, rhodamine WT, fluorescein WT
• Define geographic locations with GPS coordinates and photos
• Select measurement units
• Run low-flow sampling events with your Aqua TROLL 400/500/600 using managed workflows on your phone

VuSitu is currently available for the Level TROLL®, Rugged TROLL®, Aqua TROLL®, MPX4, VuLink®, RDO® Blue, and RDO® handheld instruments, for surface water, groundwater, coastal, wastewater, drinking water and aquaculture applications.

### 4/5 — Please fix crashing issue

*2025-09-05*

Great app but I don’t understand how there hasn’t been a fix for the app crashing randomly while using it. It’s been nearly a year now

**Developer response:** We strive to keep the app running smoothly for our users. Please reach out to support@in-situ.com for help resolving your issues.

### 5/5 — Cloud connect

*2025-06-04*

It just works! Cloud connect is a great feature that I use all the time.

### 4/5 — Ability to view graphs of downloaded data would be nice

*2024-03-26*

A very nice app to use and very intuitive. Much less clunky than Winsitu 5 however it would be great if we could view a graph of downloaded water level data after the log has been stopped and downloaded. This would make it much more useful when performing slug tests to assess the permeability of an aquifer.
