The MX Map Mobile system is designed to be used with Mapyx Quo and MX Map GIS software packages. Maps can be acquired through in-app purchase. This combined solution of Mapyx Quo and MX Map Mobile, provides a comprehensive combined system of full GIS software and a Mobile Application which are fully compatible. Currently only Ordnance Survey GB, and Ordnance Survey Ireland maps are supported but others maps and more functionality will follow. Continued use of GPS running in the background can dramatically decrease battery life. If you experience any problems please contact our help desk in the first instance before posting any negative reviews. You should always provide alternative means of navigation, and not rely on the app in any role that is critical to the safety of life or property. This product does not support any maps purchased before 2015. The Quick Start guide for this app can be found at the link below: http://www.mapyx.com/user_manuals/MXMapMobileQuickStartGuideiOS.pdf

SARLOC was originally developed in 2009 by Russ Hore as a web application that allowed Search & Rescue (SAR) teams to locate you if you were unsure of your position. If you had a data signal, the SAR team could send you a message that allowed SARLOC to obtain your location and add it to the SAR teams mapping systems. Although it has been hugely successful, it does require a data signal to show you a location before it can be passed to the SAR teams. The SARLOC App will show you a location even if you do not have a data signal. If you are in voice communication with the SAR team you can tell them your location. If they provide you with a SARKey to enter into the App, you can share your location with them directly to their mapping systems. SARLOC is not a substitute for knowing how to navigate the outside world and it is essential that you learn proper navigation techniques before venturing into the wild. SARLOC requires you to be in contact with a SAR team before you can share your location with them. Starting SARLOC will not automatically notify anybody you require assistance.

Verdict
The clearest difference is review sentiment: SARLOC at 100% against MX Map Mobile's 11%. SARLOC also leads on in-app purchases (none vs 1). MX Map Mobile's advantage is update cadence (fortnightly vs every 8 months) and iOS requirement (11.0 vs 15.6). On price, ads and device support there is nothing between them.
