Designed and developed by our Android app developer team, City of Greeley is a water station audit app, replacing the conventional way of generating landscape irrigation audit report with an automated one. Available on the Android platform, this water audit app has made it easy for water conservation specialist to generate entire landscape irrigation audit report with just a few clicks on the screen.

Without writing manually and managing paper-based reports, water auditors can make the entire report in the application, filling complete information like date of assessment, arrival time, completion time, evaluator, rain sensor, controller type, and other important details.

Clutch Rating

After spending a lot of time researching online, I settled with Space-O due to the reviews and the fact that their site claimed that conversion of excel spreadsheets to apps was a specialty (which it is). The team offered an innovative approach to mitigate communication barriers. The best thing is – the app operates and flows exactly as I had hoped! Saving many man hours and waste through simply using this app as opposed to how things were previously done. Space-o Technologies did everything I asked to them and provided the exact product I was looking for. I intentionally left the project open ended. It is my desire to see this app adapted by other municipalities along the Front Range of Colorado in order to Standardize and streamline the audit process. Looking forward to work again with Space-O. Cheers, team!”

Problems Water Auditors in Greeley Used to Face

Based in the USA, our client (Greeley Gov.) decided to create app from excel spreadsheet, allowing water auditors to generate water station audit report in the mobile app.

Previously, water auditors and inspectors were creating a report in the paper-based forms and excel sheet, filling the entire data manually. The entire process of filling information in the excel sheet and paper-based form was taking much time of the auditors.

The water auditors were filling complete information like account number, customer name, address, and type of assessment in the form and excel sheet. Many a time, excel sheet created confusion among water auditors and they were spending maximum time and efforts in maintaining such papers and sheets.

So, the Greeley Government decided to convert spreadsheet to app (water audit mobile app) so that water auditors can generate water station audit report in the app.

Water Station Audit App Review

Appreciation from Clients


Douglas Laver


The Space-O team were great to work with. Every part of the process went as per the agreed schedule, and the finished prototype met, and in most cases, exceeded my expectations. While Space-O wasn’t the most price competitive of the quotes I received, the quality of their work, professionalism, and product, was well worth the additional cost. Highly recommend, and will continue to use their services for future projects.

They performed in all aspects excellently. They have given well-appreciated discounts at various stages of the project and also with suggestions that saved cost. When it comes to delivering, they were always ahead of time. We don’t know how they do that but that’s very impressive. Their agility and customer support is on a different level, well appreciated.
