C172 Performance computes all the useful performance numbers for flight planning for Cessna model 172 and 150 aircraft. It includes calculations for takeoff, landing, climb, cruise, descent, instrument procedures as well as emergencies. It also includes an interactive hold calculator, a risk analysis tool, and an emergency glide distance calculator that handles head and tailwinds. C172 Performance is also available on other mobile devices and as a WebApp (an App that runs in a browser) that runs on a variety of platforms (PC, Mac, tablets, phones). The cloud sync feature allows flight planning profiles entered on any device to be synchronized with your other devices when connected to the Internet. C172 Performance is a free, open-source development effort and has Apps and WebApps for other aircraft. See http://pohperformance.com for complete details.
NemoScoutApp
This app provides real-time collision avoidance and traffic display for pilots, supplementing a separate transponder device. It offers visual and audible alerts for potential conflicts and displays critical flight data for backup.
- Real-time traffic display with TCAS-like interface
- Visual and audible collision avoidance alerts
- Backup flight instrument data display
- Integrated airport, obstacle, and airspace databases
- Weather information display (METAR)
- GDL90 GPS and traffic data export to EFB apps

NemoScoutApp is a companion app to the NemoScout transponder (sold separately) -a matchbox sized portable WAAS GPS with built-in collision avoidance transponder and tracker- utilized by flight schools and individuals to improve situational awareness and pilot decision making. It enables flight schools to track the position of all NemoScout equipped aircraft in their fleet in real-time. Track logs are stored on SD card in standard G1000 format and can be used with debriefing tools such as CloudAhoy. The app provides for a visual display of the traffic surrounding your present position using a TCAS-like display. Traffic is identified by triangles on top of a moving map that indicate the direction and altitude difference of any conflicting aircraft. Visual and audible warnings are provided when conflicting aircraft breach minimum clearance distances configured in the app. Different clearance distances for aircraft and obstacles can be applied when traveling en-route or when flying the pattern. The app can also be utilized to display ground speed, altitude, heading, vertical speed, attitude and rate of turn for back up purposes to your main instruments. Ground speed, vertical speed and altitude are obtained from the integrated WAAS GPS. Heading and attitude are obtained from the integrated AHRS sensor. The app includes an integrated airport database, obstacle database and airspace database that is updated every 56 days. The airport database (North America only) identifies all registered open-to-the-public aerodromes (grass or paved). Airports with weather available are identified in red and can be tapped to reveal the local METAR. Weather is received either over-the-air (for equipped aerodromes) or over the Internet (requires a 3G/4G/LTE connection). The obstacle database (North America only) contains most man-made obstacles taller than 200ft above the ground, including communication towers and windmills. The airspace database (North America only) identifies all control zones (CZ), terminal control areas (TCA), restricted CYA and CYR areas and all associated height restrictions. The app can be utilized to send GDL90 compatible GPS position and traffic information to compatible EFB apps (operating on the same WiFi access point), including ForeFlight, WingX, FltPlan Go, FlyQ EFB, iFly GPS and others. Note that attitude information is displayed in most EFB apps, with the exception of ForeFlight.

Verdict
The clearest difference is review sentiment: C172 Performance at 90% against NemoScoutApp's 0%. NemoScoutApp's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, update cadence, in-app purchases and device support there is nothing between them.
