How do I use the features on Thoughtune? 1. Identify What are Psychometric Scales? Utilize our psychometric scales, which cover 5 problematic areas - anxiety, depression, eating behaviour, substance, and alcohol dependence - to measure your progress accurately and reliably. How do they work? Unlike a rating scale, this method employs multiple questions or statements to provide precise data. So, trust this advanced tool to effectively track your growth. 2. Goals What is FIT? Try Functional Imagery Training (FIT) for a new way to make changes. Using mental imagery, it helps you stay motivated as you reach your goals. Users say it's a game-changer, making exercise, abstinence, and healthy eating something you want to do, not just something you have to do. How does it work? Discover how FIT can transform your approach to change. Backed by two decades of research, it harnesses the power of mental imagery to fuel your motivation. Mental imagery is what gives drug cravings their dominance over other thoughts, but it can also be what makes us work successfully towards a new goal despite obstacles. By blending personalized counselling with targeted exercises, FIT amplifies your drive and confidence, making your goals more achievable than ever. Research shows FIT is a new way of supporting behaviour change by strengthening motivation. 3. Retune What is CBM? Discover the power of Cognitive Bias Modification (CBM) method.

Verdict
The clearest difference is monetization model: Syd at free with in-app purchases against Thoughtune's subscription. Syd also leads on update cadence (every 2 weeks vs every 6 months). Thoughtune's advantage is review sentiment (100% vs 87%) and iOS requirement (12.0 vs 15.1). On price, ads, in-app purchases and device support there is nothing between them.
