It’s actually worthless now and I can’t even use it. ### 2/5 — Poor Design & Layout *2025-04-10* The information is not displayed in an easy to read format. The app lags causing users to have to resync to see updated data. The app logs out too often and doesn’t offer push notifications. I often find that I can walk back to my car and use my computer faster than I can fight with the app. It could be a great tool, but it needs major improvements. ### 5/5 — Developing at lightning speed *2023-11-28* Rarely does an app come along that is not only done well, but that is updated quickly. Most updates are based on client feedback. Very impressive! ### 5/5 — For Beta, things are looking great *2023-08-10* Love to see the progression of the iOS variant as it is being developed out. The parity between Android and iOS is getting smaller and smaller and things are looking amazing. Not sure why the other two reviews were written negatively since they were written as the app wasn’t even completed and was only out as Beta. Anyway…keep up the great work with this ever evolving process. ### 1/5 — Glitchy *2023-07-22* Unable to open call for service without app closing out completely. Unable to create a call for service. ### 1/5 — Needs a lot of work -long way to go *2023-04-08* Missing functionality of the end car/web browser. CAD. Missing chat function. Doesn’t show what the crime offense number is and does not show beats. Also, I deleted it because it does not even auto refresh. ## Frequently asked questions about Mark43 OnScene ### What is Mark43 OnScene?
