Gain confidence when making decisions by tapping into your gut-instinct, proved by scientific studies in the fields of biology and neuroscience.

How it works: Download the app and grant access to your HealthKit or CareKit (for Apple Watch users). Place your index-finger on the camera-lens on the back of your phone, to calculate your heart rate. Think of a question and/or something that you need to make a decision on and tap on the app to start. Keep thinking of your question and keep your index finger on the camera-lens on the back of your phone until the app completes its calculations. The results will be shown on the screen as Yes, No, or Maybe, depending on your internal gut-instinct reaction to your question. In addition to your gut-instinct responses, the app recommends YouTube and TikTok videos, based on your results. Note: If you do not have an Apple Watch, you need to do a one-time calibration before using the app. To calculate your resting heart rate and your baseline heart rate variability, the app needs permission to access your HealthKit and CareKit (if you are an Apple Watch user). Note: All results are for entertainment and educational purposes.

Geomancy Diary combines the functionality of a personal journal with the ancient art of divination. [What is Geomancy?] Geomancy is a form of divination that interprets the current situation or future developments through symbols generated from random points. It is said to have a history of over 1,200 years. Popularized in the medieval Islamic world and Renaissance Europe, it remains widely used today, particularly in African countries. [What you can do with this app] Write a Diary  Freely record your daily events and feelings. You can mark special days as "Favorites" and easily filter them via the search bar. Tags allow you to label entries with specific events, people you met, or even a 5-star rating for the day. Consult Geomancy Ask questions like "What is my fortune today?" or "Is this the right choice?" whenever you need guidance. Divination results are saved alongside your diary entries. By reviewing them later, you can reflect on how predictions manifested ("So that's how it came true!") or learn from the past ("Could I have avoided that mistake if I had read the signs deeper?"). It’s a tool to help you live better and divine better. Deepen Your Knowledge Learn the detailed meanings and symbolism behind each Geomancy figure. Customize Your Theme Change the app's color theme to suit your style. Whether you prefer bright colors or chic tones, there is an option for you. Choose from the "Simple" theme (which blends with standard iPhone/iPad aesthetics), the calm brown-based "Classic" theme, or one of the 5 unique color themes provided by fortune teller and illustrator NORI STAR CREAM! All themes support Light and Dark modes. That means 7 themes × 2 modes = 14 variations to choose from! Know Your Trends Check the Statistics screen to graphically view your trends over time. It’s fun to look back and see things like, "I got the 'Acquisitio' (Gain) symbol a lot this year!"
