A personal finance simulator showing side by side how kids, debt and your retirement timeline affect long-term wealth. A free consumer app, not a professional financial-planning tool.
Watch out · Built by a solo developer in SwiftUI — a personal modeling tool, not licensed financial advice.
FreeNo ads
What to know▼
How it works
Shows two side-by-side scenarios modeling how debt payoff timelines, child costs (using real county-level NDCP childcare data), and retirement timing interact, with a financial-independence age based on the 4% rule that updates in real time as you adjust inputs.
What's different
Compares two scenarios side by side rather than showing a single projection like most financial simulators.
Pricing
Free, no ads, no purchases.
Best for
People trying to see how having kids, carrying debt, or retirement timing would change their long-term wealth.

Opens, measures and marks up DWG/DXF CAD files in the browser without installing AutoCAD; parsing happens locally so files aren't uploaded. Aimed at contractors and reviewers, not software developers.
FreeNothing to installWorks offline
What to know▼
How it works
Opens DWG and DXF CAD files directly in the browser without AutoCAD, letting you view layers, search labels, measure distances, mark up issues, convert between DWG/DXF/PDF, and share view-only links. Supports DWG formats from R12 through 2024.
What's different
Parses files locally in the browser by default rather than uploading them to a server, and requires no AutoCAD license or install.
Pricing
Free.
Best for
Contractors, engineers, and reviewers who need to view or mark up CAD drawings without owning AutoCAD.

A tool that generates editable, parametric 3D models from a text description, an uploaded blueprint, or a sketch, aimed at people who don't want to learn full CAD.
Can export my data
What to know▼
How it works
Type what you need, drop a blueprint, or upload a sketch to generate a parametric model; adjust parameters instantly and export to STL, DXF, or SCAD.
What's different
Positioned against the steep learning curve of traditional CAD tools.
