I Built a Android App that Does Options Simulations on Your Phone's GPU, No Internet, No Accounts

Hey Guys New to Options ! So Basicly I am a Software Engg and Was pulled into learning Options ( Personal Interests ), and found that people use tools for Options Simulations and all, but most of them are desktop heavy or web based ( i think most of them do only work with internet ), So as a Young Boy, I Travel Alot.. so I can't take my Entire PC everywhere i go.. Thus i was working on my personal tool for Options Sim, Though i should post in here and take some feed back from seniors and get it tested with experienced peoples, so everyone can use it. What it currently has \- Monte Carlo simulation — 10,000 price paths computed in parallel on the GPU \- Greeks calculator — Black-Scholes with Delta, Gamma, Theta, Vega, Rho \- P&L payoff diagrams — multi-leg strategies, visual breakeven \- Stress testing — "what if market crashes 20%?" with 9 preset scenarios \- Position sizer — Kelly criterion + risk management Mostly I liked one feature i made that was : real-time mode, as you drag the sliders, the simulation re-runs on the GPU and results update instantly So I am Out here just looking for feedback on what features would actually be useful. What tools do you wish existed on mobile? Android only, Soon Launching A Best Testers Batch for people to use ( From PlayStore )
