Overview of HikeSim HikeSim is a cross-platform health and fitness application that transforms everyday exercise routines (such as neighborhood walks, runs, cycling, or indoor treadmill sessions) into an immersive visual journey through national parks, state parks, and local trails. As you move in the real world, the application advances a synchronized sequence of scenic trail photos and metadata, keeping you motivated and connected to nature. Key Features Virtual Trail Simulations: Take virtual hikes across famous locations—such as the Grand Canyon, Bryce Canyon, Petrified Forest, Lassen Peak, Capitol Reef, Joshua Tree, and local preserves. Real vs. Simulated Modes: Simulated Hikes: Distance, photos, elevation charts, and GPS checkpoints are driven programmatically by pre-recorded trail photo datasets at a selected pace. Real Hikes: Uses real-world GPS hardware, live telemetry, and actual device sensors to track your real-world path, altitude changes, and pace. Interactive Trail Maps & Elevation Profiles: Real-time map rendering tracks your position via custom green hiker annotations, alongside interactive elevation charts featuring live vertical progress indicators and altitude bounds. Custom Hike Maker (iOS): Turn your own outdoor walks into shareable HikeSim Photo Hikes by utilizing your phone's camera and location services to record geographic data, photos, and altitude profiles for upload. Voice Narration Support: Built-in audio capabilities can read trail notes and photo checkpoints aloud as you progress. Health & Fitness Integration Apple Health / HealthKit Integration: Seamlessly syncs workout metrics and telemetry directly to the iOS Health and Fitness ecosystem. Tracked Metrics: Captures and displays heart rate, active calories burned, total distance traveled, exercise duration, current pace, and Apple Activity Rings progress. Post-Workout Summaries: Comprehensive breakdown screens present total duration, distance, steps, pace, and net elevation gain/loss upon finishing a workout. Standalone Capabilities (Phone & Apple Watch) Both the iPhone and Apple Watch apps are fully capable of operating independently: Apple Watch App (Standalone): Operates with complete functionality regardless of iPhone proximity or cellular/internet connectivity. Features dedicated workout selections (walking, running, cycling). Displays real-time metrics, media playback controls, a live GPS coordinate screen, and dual-line altitude/heart rate graphs directly on your wrist. iPhone App (Standalone): Allows you to launch active workouts directly on your phone/tablet.

Forming or keeping up with new healthy habits is extremely hard, but the solution is very easy. For the first couple of days you feel motivated and it is easy but each day it gets harder and the 21 days people used to tell you you need to form a habit feels unreachable. 21 days is way too lofty of a goal, luckily theres a better way. "I'm Doing It" helps you actually form new habits. It does this by keeping it simple, you make 3 goals a day, but you don't have to achieve them all. Nobody is perfect it does not make sense to feel shame if you don't accomplish all of your goals every day. With I'm Doing It your goal is only to complete 2 of the goals a day. This is the secret to forming habits.
