Polished, user-focused apps built in London. Explore Parsa Vault — our flagship trading simulator — and see what we're shipping next.
A gamified stock, crypto, and forex trading simulator. Trade with virtual money, earn XP, and compete on the global leaderboard. Free, with real market data and no real-money risk.
We're currently in development on two more apps — a productivity tool and a cultural-movement app. Follow the ParsaDev blog for release updates.
ParsaDev is the app-building arm of Parsa Dev — an independent London-based software studio. Every app on this page is designed, coded, deployed, and supported by the same hands. No outsourcing, no agencies, no cut corners.
Our apps are built with Flutter and Dart for fast iteration across iOS and Android, backed by Firebase for authentication, data, and cloud functions. We lean into gamification where it fits — XP, levels, leaderboards — because the best educational apps don't feel like homework.
We care about three things, in order: safety (no real money at risk where it shouldn't be, no dark patterns), speed (60fps UI, cold-start under two seconds), and clarity (readable typography, generous tap targets, honest copy).
Founded by Parsa — a mechanical engineer (BEng) turned developer with a master's in Advanced Engineering Design and certificates from Harvard's CS50x and CS50 AI. The full portfolio and technical blog live at parsadev.co.uk. We publish monthly build notes there and open-source the teaching material on GitHub.
Every app ships with a plain-English privacy policy and an easy path to delete your account and data. We don't sell data, we don't run third-party trackers beyond essential analytics, and we only collect what each feature actually needs. The Parsa Vault privacy policy is the template.
