About this app

Why do we keep fighting lately? What should I study so I do not end up jobless? Why is the weight not coming off? Everyone has problems to work through, but you get that feeling of thinking and thinking without ever landing on an answer. The more you think, the more tangled it gets. The more tangled, the more tired. The more tired, the more fed up.

So how do you handle it like someone who solves problems for a living? That is why ThinkSolve101 exists. ThinkSolve101 pulls those thoughts out of your head, puts them in front of you, and helps you reason through the problem properly. From there you can solve it in the best way you can.

The idea comes from Ken Watanabe's book "Problem Solving 101." Right now we give you three tools.

**Logic Tree.** For when something keeps happening and you cannot see why. Like being broke every month. The app helps you split the problem into branches and dig into the deepest corners instead of guessing. You test your suspicions against reality to mark each one verified or rejected, and in the end you build solid solutions to deal with them.

**Decision Matrix.** For when you have several options that all look good and none you want to pass up. Two job offers, three apartments, two people you are unsure about. Lay out the criteria that matter to you, weight them, score each option. The app does the math and ranks them so you can pick the best one.

**Gap Analysis.** For when you have a goal but not a clear path. Where you are now, what you want to reach, and what it takes to close the gap. The app gives you a concrete, worked-out plan to get there.

Daily life, work, studying, even love, we will help you find the best way through.

Everything stays on your device. No account, no login, no internet.

There are more features on the way. Download it now and let us dig into what your problem is together.

Remember: "If you cannot solve it, draw it out."
A pro toolkit to help you solve every hard problem in your head.
