About DingTou App
DingTou App is a dollar-cost-averaging (DCA) calculator for US stocks and ETFs. You enter a ticker, set a schedule and amount, and the tool pulls historical prices and shows you how that strategy would have performed.\n\n\n\n## What it calculates\n\n\n\n- DCA returns over a date range you choose, using actual historical prices.\n\n- Compound growth, so you can see the effect of reinvesting.\n\n- Side-by-side comparison of multiple DCA strategies on the same chart, which is the actual useful part. Reading "strategy A returned 8.2%" is less informative than seeing A against B against C on one curve.\n\n\n\n## How you use it\n\n\n\nType a ticker, pick a date range, set the contribution amount and frequency. The tool does the rest. No account, no export limits on the free tier.\n\n\n\n## Caveats\n\n\n\nBacktests describe the past, not the future. A strategy that beat the market from 2015 to 2021 tells you nothing about 2026. Treat the curves as a way to understand how a strategy behaves, not as a prediction.

What to consider before using DingTou App
DingTou App is one of many tools in its category. Before committing to it, weigh a few practical points that tend to decide whether a tool actually fits your work:
- Match the tool to your real task, not to its feature count. A tool that excels at your specific job beats one with a longer checklist you will never use.
- Check how it fits your existing workflow — integrations, export formats, and whether the output needs heavy manual cleanup.
- Read the license and pricing terms for commercial use, especially if you plan to publish or resell what the tool produces.
