TrackChart lets you track any numerical data you like and displays it in charts. You can track your weight loss journey, how many pages you read in a day, push-ups, scientific data ... Start by adding your first topic. Choose a name, pick a color palette, start tracking. You can track positive and negative numbers, decimals or integers, it all works. Each entry is automatically timestamped. But you can also change this timestamp to record something you did last Wednesday. Supports automatic iCloud sync across all your devices.

Think through any problem. The world's best engineers, founders, and investors don't just work harder โ they think differently. They use mental frameworks: structured approaches to decisions that cut through complexity and reveal what matters. Outthink puts 16 of these frameworks in your pocket. What's inside: โข Eisenhower Matrix โ Prioritize ruthlessly. Separate urgent from important. โข Two-Way Door Decisions (Bezos) โ Know when to move fast and when to deliberate. โข Inversion (Munger) โ Solve problems by thinking backwards. Avoid failure modes to succeed. โข The 5-Step Algorithm (Musk) โ Question, delete, simplify, accelerate, automate. In that order. โข Pareto 80/20 โ Find the vital few inputs that drive most results. โข First Principles โ Break problems down to fundamental truths and rebuild. โข Pre-mortem โ Imagine failure before it happens. Then prevent it. โข And 9 more frameworks from thinkers like Feynman, Boyd, and Buffett. How it works: Each framework is interactive. Enter your actual decision, goal, or problem โ and work through it step by step. Get actionable insights, not just theory. Free to start: 4 complete frameworks are free forever. Unlock all 16 (plus future additions) with a one-time Founding Member purchase โ no subscriptions. Built for doers: Whether you're making a career move, prioritizing a product roadmap, or deciding whether to buy that house โ Outthink helps you think it through. "I think it is possible for ordinary people to choose to be extraordinary." โ Elon Musk

Verdict
The clearest difference is in-app purchases: TrackChart at none against Outthink's 1. TrackChart also leads on update cadence (every 3 days vs weekly). Outthink's advantage is iOS requirement (15.1 vs 18.1). On price, ads and device support there is nothing between them.
