Hi, I'm an independent developer, and I built Spotter because I wanted a strength tracker that's fast, private, and actually feels like it belongs on iPhone. No account to make. No ads. No one watching what you do. Just you and your training. Build a workout once, then start it with a tap. Log every set with one hand, keep an eye on your rest timer right from the Lock Screen, and finish to a little celebration of what you just lifted. WHAT MAKES IT DIFFERENT • It's genuinely private. Your workouts and history stay on your device and sync through your own iCloud. I never see your data. • It's made for the gym floor. Big, one handed controls, instant logging, and a rest timer with haptics. • It feels like progress. Personal records pop the moment you hit them, plus a weekly goal ring, streaks, trend charts, and badges to earn. TRACK EVERY LIFT • 100+ exercises you can browse by muscle, equipment, or type • Reps and weight, or timed holds for planks, carries, and conditioning • Machine settings and notes for each exercise • A "last time" reminder, so you always know what to beat STAY MOTIVATED • Personal records called out the moment you set them • A weekly workout goal with a streak that doesn't punish your rest days • Achievement badges for your milestones • A year long activity heatmap, and trend graphs for each exercise (top set, estimated 1RM, total volume) EVERYWHERE YOU TRAIN • An Apple Watch app, so you can log sets from your wrist • A Live Activity on the Lock Screen and Dynamic Island, so you can skip or add rest without opening the app • Home Screen widgets for your next workout and recent activity • Start a workout from Control Center, the Action button, Siri, or Spotlight WORKS WITH APPLE HEALTH • Saves your finished workouts to Apple Health (type, duration, energy, volume) • Can read your body metrics to personalize things, and shows you exactly what it uses Think of it as the piece Apple Fitness leaves out: structured strength training, done properly. SMART, AND ON YOUR DEVICE (on supported iPhones) On iPhones with Apple Intelligence, Spotter can put together a workout for your goals and reshape it for the day when you're short on time or low on energy. It all happens on your device, never on a server. FAIR, SIMPLE PRICING Spotter is free with two custom workouts and unlimited logging, so you can properly try it before you buy. If you want more, go Pro to unlock unlimited workouts: a low monthly plan, or a one-time lifetime purchase if you'd rather pay once and own it forever. Either way it keeps Spotter independent, private, and ad-free. Thanks for giving it a try. If something could be better, I would genuinely love to hear about it.

Manifestation doesn’t fail during your morning meditation. It fails during your 2:15 PM autopilot reaction. You can visualize your highest self, journal your intentions, and practice breathwork for 15 minutes every morning. But your brain does not change through passive wishing—it changes through physical neuroplasticity. The remaining 15.5 waking hours of your day are run by your subconscious Default Mode Network (DMN). Every time an unexpected confrontation, frustrating email, sudden setback, or comparison loop strikes, old neural conditioning fires automatically. If you react from old habits, your brain physically strengthens those exact pathways. You spend the entire day embodying your past self, nullifying your morning intentions. Interrupt is the tactile instrument engineered to close the manifestation gap. In just 3 conscious seconds, catch reactive autopilot in the split-second before it speaks, choose your sovereign persona response, and watch your neuroplastic rewiring take physical form in an interactive 3D brain mesh and living Zen sanctuary. THE NEUROSCIENCE OF REAL-TIME REWIRING Donald Hebb’s foundational law of neuroplasticity states: "Neurons that fire together, wire together." To manifest a new reality, you must break the conditioned loop at the exact moment of friction. Interrupt provides the physical pause that stops old pathways from firing and anchors your new identity into muscle memory. HOW IT WORKS 1. NOTICE THE SPLIT-SECOND FORK: An everyday trigger appears—a setback, opportunity, confrontation, comparison, or wandering distraction. 2. THE 3-SECOND CATCH: Press your iPhone Action Button, tap your Lock Screen complication, or touch the app. The physical action halts autopilot conditioning. 3. EMBODY YOUR CHOSEN PERSONA: Pivot from the old reactive story to your conscious declaration (e.g., "I respond from centered stillness"). 4. REWIRE SPATIALLY: Watch synaptic pathways illuminate in a real-time 3D brain point-cloud and nurture your living Zen sanctuary. KEY FEATURES • 3-SECOND REFLEX CATCH Frictionless micro-logging. No lengthy journaling required when you are in the middle of your day. Catch subconscious impulses in real time before autopilot takes over. • 3D NEURAL CONSTELLATION MAP Witness your neuroplasticity live. Powered by SceneKit, every conscious pause physically anchors and illuminates synaptic clusters within your Prefrontal Cortex and Conscious Observer hubs. Take orbital cinematic tours through your evolving neural architecture. • LIVING ZEN SANCTUARY & DIURNAL SKY A generative SpriteKit world that physically mirrors your inner state. Watch the camp hearth ignite with presence, the windswept bonsai pine grow resiliently against mountain winds, and true astronomical moon phases illuminate your landscape. • PERSONA & IDENTITY ARCHITECTURE Declare who you choose to be. Define your active persona, anchor target traits, and track your lived alignment through every daily friction point. • 30-DAY SCRUBBER & SUBCONSCIOUS ANALYTICS Travel through time with the interactive journey scrubber. Watch time-lapses of your neural growth, track synaptic density, and witness your transformation day by day. • HARDWARE INTEGRATION & WIDGETS Map Interrupt directly to the iPhone Action Button for instant 1-second pause capture. Glance at minimal Lock Screen complications and ambient Home Screen widgets. • BIOMETRIC SHIELD & 100% PRIVATE Your inner thoughts and identity reflections are sovereign. Zero third-party cloud tracking, zero accounts, zero analytics telemetry. All data is persisted locally on your device, protected by optional FaceID / TouchID biometric security.
