Here is the long-awaited successor to our critically acclaimed flight simulator. It simulates the Space Shuttle approach and landing in incredible detail and accuracy. This is a remaster of our original F-Sim Space Shuttle, completely rewritten from scratch. New features include: - Console quality graphics - Interactive tutorials - White Sands as a third landing site option - Orbit mode F-Sim Space Shuttle combines realistic flight simulation with stunning graphics and fun gameplay. You’ve never landed a Space Shuttle before? We’ve got you covered: Included are several tutorials with varying degrees of autopilot assist. Our landing analysis and scoring system tells you exactly how to improve your next landing. It will make you come back and try again. Each flight starts at either 10,000 feet, already aligned with the runway, or at up to 50,000 feet, before banking into the heading alignment cone. During descent, the Orbiter is an unpowered glider, so you will only have one chance to get it right. Astronauts used to call it a flying brick: Because of its 200,000 lbs. gross weight and low lift over drag ratio, the approach is six times steeper and two times faster than a typical airliner approach. After your first safe touchdown, chase that perfect landing, compare your high scores online with your friends, earn medals, and unlock achievements. Experiment with different wind conditions, night approaches, and even emergency scenarios or system failures. At the end of each flight, watch a replay from different camera angles. You control the Orbiter’s pitch and roll axes by tilting your device. Alternatively, you may switch to on-screen analog sticks or use a gamepad. Rudder, speed brake, gear, and chute are usually handled by the autopilot, but you can have full manual control if you like. For beginners, we’ve added rectangles that visualize the desired approach path. Simply try to stay within the corridor of rectangles, and they’ll guide you right to the touchdown point. Advanced pilots can turn them off and rely on the instruments in the head-up display (HUD) instead. The simulated guidance, navigation and control (GNC) systems are authentic replications of their counterparts in the real Orbiter, and the HUD features all the instruments real Space Shuttle commanders used to employ to skillfully land this unique aircraft. Now it’s your turn to give it a try. A new orbit mode lets you take the Orbiter for a spin around the planet, and we’re working on a full atmospheric re-entry scenario, which, among other new features, will be released as free updates in the coming months. There are no ads or in app purchases, and we don’t collect any personal data.

Red Flag Sim is a modern military aviation simulator built specifically for mobile devices. Mobile platforms have long lacked a combat flight simulator with genuine depth. Red Flag Sim was created to change that, bringing complex flight and avionics systems to mobile through a control scheme designed for touchscreen devices. Our goal is to give players the authentic feeling of operating a fighter aircraft—from trim, angle of attack, energy management, and G-loading to radar, navigation, warning systems, and weapons employment. Every system is modeled around real-world principles and publicly available information. 【IN-DEPTH F-15C SIMULATION】 The current version features the F-15C, demonstrating the level of simulation depth planned for every future aircraft module in Red Flag Sim. Manage the aircraft’s flight state and energy, operate its radar and avionics, employ weapons, navigate, approach, and land safely. This is not an arcade shooter built around simply aiming and firing—it is a flight experience that rewards learning, practice, and continuous improvement. 【REALISTIC FLIGHT DYNAMICS】 Experience how trim, angle of attack, stalls, G-forces, and energy affect the aircraft. Speed, altitude, payload, and control inputs all influence its performance and handling. 【RADAR AND AVIONICS】 Use multifunction displays, fire-control radar, radar warning systems, and navigation equipment to build situational awareness, locate targets, and complete engagements. These systems are designed around meaningful operation and interaction—not merely visual interface effects. 【TRAINING AND QUICK MISSIONS】 Learn essential flying skills, avionics operation, weapons employment, and landing procedures through dedicated F-15C training missions—or jump directly into the cockpit with a selection of quick missions. 【CREATE YOUR OWN MISSIONS】 Use the tactical mission editor to place units, define routes, configure the operating environment, and create your own custom scenarios. 【AN EVOLVING INDEPENDENT PROJECT】 Red Flag Sim has been independently developed by a solo developer and continues to evolve. New terrain, environmental effects, aircraft modules, missions, and simulation systems will be introduced over time. If you have been waiting for a more serious and in-depth combat flight simulator on mobile, welcome to the cockpit of Red Flag Sim. Prepare for takeoff.

Verdict
The clearest difference is in-app purchases: F at none against Red Flag Sim's 3. F also leads on ratings volume (526 vs 61). Red Flag Sim's advantage is update cadence (every 3 days vs every 2 months) and review sentiment (88% vs 62%). On rating, ads, chart position and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
F costs $4.99 and Red Flag Sim $0.99 up front. Red Flag Sim sells 3 one-off in-app purchases. F asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 4.6 for F against 4.6 for Red Flag Sim. That said, the two scores are not equally well evidenced: F has 526 ratings behind it against 61, so its average is the more settled of the two. Written reviews are what separate them: 62% of F's written reviews are positive against 88% of Red Flag Sim's.
F ships an update every 2 months, Red Flag Sim every 3 days. Both last shipped on October 15, 2026.
