10/02/2025

Sixth Sense Training by Dae Hyun Kim is a lightweight iPhone app offering eight quick mini-games (angle, area, calculate, color, count, dialtone, length, time) designed to test and improve perceptual estimation skills and basic calculation at progressively challenging levels.

For users of small (4.7") iPhones: Please note that this game may not perform optimally on smaller screen devices.

Sixth Sense Training offers an opportunity to examine and develop your intuitive perception beyond the traditional five senses (sight, hearing, smell, touch, and taste). Currently, the game includes eight sub-games (with additional ones planned), detailed below. Reaching level 1,000 does not mark the conclusion of each sub-game; gameplay can continue infinitely beyond that point. A single purchase grants access to all current and future game content.

1. Angle: Which of two given angles is larger? Enhance your ability to gauge angles accurately.

2. Area: Which object has a larger area? The objects are rectangles, ellipses, or triangles. Refine your sense for measuring area dimensionally.

3. Calculate: Which numerical value is greater? Each comparison involves sums, differences, products, or quotients of two numbers. Strengthen your fundamental calculation intuition.

4. Color: Which item exhibits a more intense red/blue/green/brighter hue? Sharpen your color discrimination skills for closely similar shades.

5. Count: Which set contains more circles? Improve your ability to quickly count objects at a glance.

6. Dialtone: Which dial tone more closely matches a given reference? Enhance your skill in distinguishing DTMF signals.

7. Length: Which object is longer? Increase your sensitivity to measuring lengths accurately.

8. Time: Which interval is longer? The first object appears for a certain duration in the top window, followed by a second object in the bottom window for a different length of time. Select the one displayed for the longer period. Develop your intuitive sense for temporal measurement.

Thank you for reviewing this training tool.

Infinite gameplay beyond level 1,000 — high replayability for users who enjoy improving scores
Small download size (~978 KB) — minimal storage and quick install
One-time purchase model (buy once, future sub-games included) — no apparent subscription required

Privacy disclosures are incomplete — developer has not provided app privacy details to Apple (privacy policy exists but Apple listing shows “No Details Provided”)
Very few user reviews/ratings (only 2 visible in the App Store) — limited social proof and feedback
Last known update in June 2020 — long gap without recent updates may indicate limited ongoing maintenance or feature development
Single-developer/indie app — may limit resources for support, accessibility features, or rapid bug fixes
Limited platform visibility — appears primarily on iOS (App Store) with no broad cross-platform presence advertised
UI/UX and accessibility details unclear from listing — no clear information about support for accessibility options (VoiceOver, dynamic type, colorblind modes)
Dialtone game and other sound-based features may be device-dependent and could have inconsistent behavior across hardware (and required steps had needed bug fixes previously)

FAQ

What is Sixth Sense Training by Dae Hyun Kim?

Sixth Sense Training is a mobile game designed to test and improve a player's intuitive judgment across several perceptual and cognitive tasks (angle, area, calculation, color, count, dialtone, length, and time).

Which mini-games (sub-games) are included?

The app currently includes eight sub-games: Angle, Area, Calculate, Color, Count, Dialtone (DTMF recognition), Length, and Time. More sub-games may be added in future updates.

How do the sub-games work?

Each sub-game asks you to choose which of two items is larger, longer, more, or closer to a target (for example, larger angle, greater area, more red, more circles, closer dialtone, longer length or time, or greater calculation result). The goal is to build an intuitive sense for those attributes.

Are there levels or limits to play?

Each sub-game has levels that increase in difficulty, but level 1,000 is not a hard limit — you can continue playing infinitely beyond level 1,000.

What platforms and device requirements are needed?

The iOS app requires iOS 13.5 or later and is listed for iPhone (note: the developer warns it may not work well on small 4.7" iPhones). The app is available on the Apple App Store. For other platforms, check the developer site for updates.

Is the app free or paid?

How does the app handle privacy and data?
