IP Inbound
This app assists pilots in achieving precise time-on-target for critical flight maneuvers. It calculates optimal run-in speeds and provides guidance for maintaining exact arrival times at designated locations, crucial for coordinated events or performance evaluations.
- Precise target coordinate entry
- IP bearing and distance selection
- Desired ground speed input
- Time on target (TOT) calculation
- Pre-IP lateral guidance
- Post-IP lateral guidance
- Automatic turning time inclusion

IP Inbound is an application that helps pilots fly an IP-to-target run to an accurate time on target. This application is useful for formation demo pilots, or pilots who participate in simulated tactical events, and need to be over a target at a precise time. THE PROBLEM Maybe you are lead of a formation flight over a ceremony and you have specific time on target (TOT), or you are being tested on your ability to put a flour bomb on a mock target at a precise moment. In either case, you are likely given three pieces of information: 1. Your target location 2. A desired time on target 3. An initial point (IP) or run-in direction Your job is to select a run-in speed, and plan your arrival over the IP so that you arrive over the target at TOT. For flights that must coordinate with a band or pyrotechnics display on the ground, or for aircraft that are being tested on their timing, seconds matter. THE SOLUTION This iOS application allows you to select or enter a precise target coordinate, choose an IP bearing and distance, and a desired ground speed, and then enter your TOT. It then provides you with useful information during each phase of your flight: ON THE GROUND, it shows you a countdown to your TOT for takeoff planning. AIRBORNE, PRE-IP it provides you with lateral guidance to the IP, and a countdown for when you must exit the IP to make your TOT. It will also automatically provide you with direct-to-target guidance if it calculates that you must skip your IP in order to make your TOT. AIRBORNE, POST-IP it provides you with lateral guidance for the IP-to-target run, and tells you to speed up or slow down to meet your TOT. The app automatically includes turning time in its calculations: For example, if you are running very early and opt to make a 360 or an S-turn during the IP-to-target run, it will include the time needed to complete the turn in its estimated-time-of-arrival (ETA) calculations, and airspeed guidance.

Verdict
The clearest difference is update cadence: IP Subnet Network at weekly against IP Inbound's every 3 weeks. IP Subnet Network also leads on iOS requirement (6.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
