SelfQ Space

You know why it keeps happening. It happens anyway. The same argument. The same decision you keep putting off. SelfQ Space is made for that point: you feel stuck, and understanding it has not moved anything. HOW IT WORKS 1. Describe in your own words what weighs on you: a situation, or up to three things you notice. 2. Every state has its own number. SelfQ Space calculates yours from your words, using a fixed method and no AI. Your number becomes your Qode, a visual pattern. 3. You look at your Qode in a fixed 72-second sequence. After a 3-2-1 start the image appears and disappears in set intervals. No audio, no instructions, no timer on screen. The 72 seconds are the length of the sequence. They are not a promise about what happens afterwards. AFTER THE QODE - A journal with five scales: Physical, Emotional, Mental, Energy, Positive events around you - A daily reflection question - A progress chart - Optional reminders 1 day, 3 days and 1 week after a Qode, created on your device YOUR DATA Stored in the EU. No ads, no tracking across apps, no third-party analytics. You give explicit consent before your text is processed and can withdraw it at any time.

New subscribers get a 7-day free trial that includes 1 Qode. After the trial the subscription renews automatically every month at the price shown in the app, unless you cancel at least 24 hours before the end of the current period. You manage and cancel the subscription in your Apple ID settings. Terms of use: https://selfq.space/terms Privacy policy: https://selfq.space/privacy

Verdict
The clearest difference is price: SelfQ Space at Free against Yi Jing's $4.99. SelfQ Space also leads on update cadence (every 6 days vs every 4 months). Yi Jing's advantage is device support (3 vs 1). On ads, in-app purchases and iOS requirement there is nothing between them.
