Simple Trade Calc
Your Intelligent Trading & Portfolio Assistant
Comprehensive Android application combining a precision spot profitability engine (Break-Even, Stop-Loss, Risk/Reward) with portfolio tracking, trading simulator, DCA accumulation projections, and serverless background price alerts.
From Instant Order Calculation to Complete Portfolio Oversight
Simple Trade Calc (STC) is an intelligent all-in-one assistant built for independent traders and crypto investors. It combines a lightning-fast Simple Mode to calculate every trade entry in 3 seconds (Maker/Taker fees, Break-Even, Stop-Loss, R:R ratio) with a robust Advanced Mode dedicated to portfolio tracking.
Free from cloud server dependencies and mandatory registrations, the app adheres strictly to the Local-First paradigm: your transactions, trading plans, and balances are stored and encrypted locally on your Android device.
Zero Sizing Errors Under Market Pressure
In digital asset and financial markets, the primary cause of liquidation is not poor timing, but human position sizing errors or underestimating the compounding drag of exchange fees.
Mental calculations under volatile market pressure inevitably lead to avoidable losses. STC replaces guesswork with deterministic arithmetic rigor, while providing investors with a private, structured environment to journal trades, test strategies without financial risk, and plan dollar-cost averaging.
Spot Order Sizing & Break-Even Analysis
Input your allocated capital, exchange Maker/Taker fees, and target: STC instantly calculates the exact Break-Even exit price and protective Stop-Loss before you execute.
Multi-Token Portfolio Management & Trading Journal
Track the consolidated value of your holdings, average purchase cost (DCA), net P&L performance, and log every trade into a private journal without ever sharing your balances.
Paper-Trading Simulation & Background Price Alerts
Test new strategies using the virtual simulation engine without risking real capital, and set Take-Profit / Stop-Loss triggers monitored locally in the background on your device.
Trading Intelligence Without Surveillance
The mission of Simple Trade Calc is to deliver the ultimate crypto trader toolkit with total privacy and local sealing:
- • 100% Local-First architecture: no accounts to create, zero cloud databases, eliminating any risk of balance leaks or strategy espionage.
- • Fair and transparent Freemium model: generous free tier for Simple Mode, and a one-time/transparent Premium upgrade for unlimited calculations, sessions, and alerts.
- • Full network transparency: only public exchange market tickers are fetched on-demand for live prices, with zero transmission of personal user identifiers.
