Mental Aspect
Read full descriptionHide full description
Mental Aspect is a mindset journal designed to help you reflect, practice, and grow. Take a few minutes each day to slow down, understand what's on your mind, and practice better ways of thinking and responding. Instead of simply consuming ideas about personal growth, Mental Aspect helps you turn what you learn into something you can actually use in everyday life. ### DAILY REFLECTION Slow down and put your thoughts into words. Thoughtful prompts help you reflect on what's happening, what matters to you, and how you want to respond. ### MENTAL REPS Build a stronger mind through practice. Mental Reps are small exercises designed to help you practice better ways of thinking and responding — from focusing your attention and developing self-compassion to changing unhelpful patterns. ### PERSONALIZED REFLECTION Make your reflection more relevant to you. Connect your reflections with what you're currently working on and focus your attention on what matters most to you right now. ### DAILY PRACTICES Start with something small. Simple exercises help you apply what you're learning and turn better intentions into actions you can use in everyday life. ### IDEAS WORTH REMEMBERING Explore ideas from psychology, personal growth, and everyday life. Save the ideas that resonate with you and build your own personal library of insights worth coming back to. ### TURN INSIGHTS INTO PRACTICE Don't just save something that inspires you. Turn meaningful ideas into practical exercises you can use in real life. ### UNDERSTAND YOUR PATTERNS Look back at your experiences and reflections over time. Notice how your thoughts, feelings, and practices evolve, and gain a deeper understanding of yourself. ### YOUR DAILY LOOP Discover → Understand → Practice → Reflect → Adapt → Grow Mental Aspect is built around a simple idea: **Don't just consume the message. Live it.** Reflect on what matters. Practice what you want to change. And keep building a stronger, calmer mind. Terms of Use: https://www.mentalaspect.net/terms

Moonfast is a quiet intermittent-fasting timer for people who would rather not be shouted at by an app. Pick a protocol — 16:8, 18:6, 20:4, OMAD, or your own hours — and start. The ring shows how far into your fast you are, and keeps counting if you go past your goal. LIVE ON YOUR LOCK SCREEN Start a fast and it appears as a Live Activity, so the timer is there without unlocking. The Dynamic Island keeps it at a glance, and Home and Lock Screen widgets show your current fast, your streak and your longest fast so far. A GENTLE STAGE TIMELINE As the hours pass, Moonfast describes the stages people commonly associate with fasting windows. It is written to be interesting, not instructive — bodies differ, and the app says so. YOUR HISTORY, HONESTLY A calendar of the fasts you have finished, current and longest streaks, weekly averages and personal bests. When there is not enough data yet for a number to mean anything, Moonfast says that instead of inventing one. WEIGHT, SMOOTHED Log your weight, or connect Apple Health and let it come across on its own. Moonfast draws a smoothed trend line through the daily noise, because day-to-day weight moves on water alone. Connecting Apple Health is optional, and the app works fully without it. VITALS, SIDE BY SIDE If Apple Health has your resting heart rate, heart rate variability or time asleep, Moonfast charts them next to the days you fasted. It shows the readings; it does not tell you what they mean. Readings come from an Apple Watch or another app — Moonfast only reads them. HYDRATION Log water, tea or coffee while you fast. If you want a daily target you can set one — Moonfast will not pick one for you. PRIVATE BY DEFAULT No account. No servers. No analytics. Everything you log stays on your iPhone, and you can export all of it as JSON or delete every trace of it whenever you like. Moonfast is a timer and a log. It is not a medical device, and it does not give medical advice, diagnosis or treatment. Talk to a doctor before you change how you eat, especially if you take medication or have a health condition. Moonfast is not intended for anyone under 18, for anyone who is pregnant or breastfeeding, or for anyone with or recovering from an eating disorder.
