For makers deciding what to build
Guides
Practical, evidence-informed guides for the moment you have an idea and no clear read on whether it’s worth your months. Each one is a real process you can run on paper — the free scorer just helps you stay honest about which parts you’ve actually checked.

A five-step ladder of cheap tests — problem framing, past-behavior interviews, existing evidence, willingness-to-act, and a kill-threshold you set in advance — so you’re proven wrong quickly instead of right slowly.
Read the guide →An idea scoring framework: how to score a startup idea
A reusable four-circle rubric — Care, Capability, Need, and Paid path — that rates an idea’s separate parts, refuses to let one strong circle hide a fatal one, and points you at your next cheapest experiment.
Read the guide →IdeaSweetSpot is a calm reflection and prioritization tool for people deciding what to build. It is not financial, legal, career, tax, or mental-health advice, and it makes no guarantee of income, demand, or success. Ikigai is used here as a lens, not an authority. Your entries stay on your device. Everything here is the opinion of the author — evidence-informed where sources are named, honest maker craft everywhere else. © 2026 Apps 4 That LLC.
