Read full description

Time-boxed reflection, then decide. Decision Timer is a structured decision system built around deadlines, guided reflection, and outcome learning. Instead of endless pros and cons, you give yourself a time limit. When the timer ends, you pause, reflect with prompts, then commit to Yes or No. This is not a habit tracker. Not a journal. Not a productivity system. It is a binary decision tool with built-in reflection and learning. KEY FEATURES • Guided reflection step When your timer ends, optional prompts help you think clearly before choosing (e.g. “What does your gut say?”) • Decision categories Organise decisions by Work, Money, Relationships, Health, or Other. Filter your history by category. • Outcome tracking After a decision, later record: “Would I decide the same again?” (Yes / No / Skip) to spot patterns. • Custom timers Set deadlines from 5 minutes to 24 hours. Get notified when it’s time to decide. • Multi-language support Available in 7 languages. FREE • Up to 3 active decisions • Full reflection, categories, and outcome features PREMIUM (one-time purchase) • Unlimited decisions • Full history forever • Pay once. No subscription. Ideal for job offers, big purchases, relationship choices, and everyday dilemmas. Privacy-first. All decision data stays on your device. No accounts. No tracking.
