Precise Station/Offset - Try it & Dump OnStation
NRG created Alignment Viewer years ago and long before OnStation came onto the market. At an incredible price with no subscription fees, Alignment Viewer provides extremely accurate Station & Offset information from either your location or wherever you place the crosshairs on the screen. This allows you to get the exact same Station/Offset that a GNSS rover would resolve. For example, you can select the end of a nearby pavement marking skip and wheel from there and you’ll be easily within the nearest foot or decimeter. Simply create a project, import your .xml file (the worldwide file format for alignments), choose which alignment you want to work from and you’re ready to go! Another incredible feature is the ability to export your project’s line-work to a Google KML file and load that into your Alignment Viewer project(s) as well. It’s like having a data collector in your pocket. I also love the fact that you can explore a project from the office right on your phone - simply shut off the GPS button on the main screen and use the crosshairs to navigate to a specific station/offset. Alignment Viewer supports projects in what seems like thousands of of coordinate systems including the State Plane systems used in the US. I just finished the oversight of a $160 million roadway project and had all 30 of our inspectors up and running with this app after sending out a single email. This resulted in the projects thousands of daily work reports having incredibly accurate and repeatable location data which made project closeout a breeze. Part of this project included 30 miles of concrete patching. When I compared the concrete patching logs against my Leica GS18 Base/Rover I found his log to be accurate the nearest foot on a vast majority of the 3000 concrete patches we performed. I recall the days when it was hard find “where you were” on a patch log because the stationing was all off by +/-50 Ft and am so glad that headache is a thing of the past. With modern iPhone’s having dual-frequency GNSS, I only need to pull out the survey gear for high precision sub-centimeter work. For everything else Alignment Viewer works just as good. Lastly, keep in mind that OnStation stole this idea from NRG and is charging $1000/year for the same capability with some added gimmicks.
Give this app a try before falling into OnStation’s aggressive advertising and sales team’s efforts to significantly overcharge your firm. Support NRG, who in my view is providing this app as a public service. Thank you to NRG for the years of value you have provided to the world’s construction industry!!

Station & Offset, Bug Free, and Subscription Free. Perfect!
This developer has provided an app that will calculate your station and offset based off a universal .xml alignment file. This has not been done by any other developer and as a road & bridge construction inspector who works on very large projects - I am so thankful. This has increased the quality and accuracy of my deliverables and changed the way my team works in the field. It is not feasible for everyone to carry and GNSS Rover to acquire their station and offset, this app fills that gap. I hope it gets the support it needs for continued maintenance/support. Over the several years of using it, NRG has been quick to resolve bugs that come with changes in iOS and Google APIs. Again, thank you NRG!

Still crashing
The app is still crashing after importing alignment. Please have someone test the app by importing alignment and settings before updating app.
Unusable
Doesn’t work with iOS 18 updates. Once you close the app once you’ll have to delete it and redownload everytime to regain access.
Was great several years ago.
This app was phenomenal 4 years ago. But now it crashes continuously. Resulting in deleting the app and uploading the files again and again. It’s a tool I use daily and thankful for when it works. Just very inconvenient. If the app is updated and stops crashing my review will change to a 5 star.
App won’t open
App works great when it actually opens. Every few days it stops letting me open it. Deleting and re-downloading seems to work but then it does the same thing after a day or two. iPhone is completely up to to date. Hoping there will be a fix soon.
Good When it works
Expensive app and seems to have a lot of down time on IOS.
Would be nice to be able to take multiple photos within the app without having to click the camera button per photo.

It’s been reliable until today, Jan 30, 2024
iPhone 15 Pro, iOS 17.2.1, app version 2.9996. The app won’t open anymore. It loads then aborts after about 1 second. I even deleted the app, shutdown phone, fresh install, restart and still no luck. I tried email to developers but no response. There really isn’t a tech support contact.
Got worst
Not sure what got improved but app crash after update and require me to reinstall to get to work. Lost all my data points in the process. They should really keep the data in a folder that wouldn't be erased if u installed. Also light gray backdrop on white text is a terrible choice to display information. Really have to strain to read.

Had to reduce two stars because Google map and satellite imagery no longer works. The developer stated that google changed the way apps access their data and they do not currently have a solution to resolve. The app has not been updated in three years. I hope the developer can correct this issue for all of those who have bought the app. I recommend the developer charge $49.99/year to assist in keeping the app updated. I would also like to see station equations supported on iOS.

Good but missing HS2 grid still
Please add EPSG:9300 HS2 survey grid
Display bug when rotating.
Display bug when changing from portrait to landscape then back to portrait.
Bug reported to developer several months ago. Report was acknowledged but the issue still has not been resolved.

Great
Perfect for stationing on projects
Excellent
Great app for easily locating and recording your position on any site
