Interoception Activity Tracker (IAT) is a private wellness and self-awareness companion designed to help you notice what is happening inside your body, record what you experience, and reflect on patterns over time. NOTICE Use structured body check-ins and an interactive front-and-back Body Map to capture where you notice sensations and how they feel. RECORD Save body observations alongside mood, food, hydration, notes, and everyday context. Talk Check-In also lets you speak or type what you are noticing, review a structured draft, make corrections, and choose exactly what gets saved. REGULATE Use guided breathing sessions when you want a quiet moment to slow down, reset, or refocus. Adjust breathing timing and keep a history of completed sessions. REFLECT Review Insights based on your own recorded history, explore patterns across time, and use the Reflection Center for daily, weekly, and monthly views. On supported Apple devices, optional on-device Apple Foundation Models can help create private reflections from structured journal information. YOUR DATA, YOUR CONTROL IAT keeps its primary journal data on your device. When iCloud sync is available, supported records can synchronize through your private Apple CloudKit database tied to your Apple Account. Diaclastic Studios does not operate a separate journal-data backend, sell IAT wellness records, or use your journal content for advertising. You can also: • Export journal data as CSV • Create PDF summaries • Make a full IAT backup for import or recovery • Protect the app with Face ID, Touch ID, or device authentication where available • Use supported Siri and App Shortcut actions to start common workflows more quickly INTEROCEPTION PRO IAT is a free download. Normal product use requires an Interoception Pro subscription. Monthly and yearly plans unlock the same complete app experience. Eligible users may receive a 14-day introductory trial through Apple. Pricing, availability, and trial eligibility are confirmed by the App Store at purchase. IAT is a wellness and self-awareness tool. It is not a medical device, does not provide medical advice, and is not intended to diagnose, treat, cure, mitigate, or prevent any medical or mental-health condition.

Within is a pacing app for people whose energy is limited and unpredictable. Set today's capacity, log what things cost you, keep a reserve and everything stays on your iPhone. Within is built around the energy envelope: an amount you have for today, with a reserve line held back so an ordinary day doesn't have to use everything you have. You say how much you have, tap what you did, and Within shows where the day went. There is nothing to fill, nothing to beat, and nothing that congratulates you for doing more. Everything runs locally. There is no account and no server, Within contains no network code at all, so nothing you log can leave your iPhone unless you export it yourself. HOW IT WORKS Set today's capacity in the morning. Your first feeling is enough, it's an estimate of your day, not a measurement. Tap what you did as the day goes on. Costs are set up once, so logging later takes a tap. Watch the envelope and stay below your reserve line. It's a floor, not a target. In the evening, note how the day went if you want to. Skipping is a complete answer. KEY FEATURES • Today's envelope with a protected reserve line, and a breakdown of where the day went • Activity presets with the cost and length that match your own experience, adjustable any time without rewriting past entries • Upright time and rest tracked separately • Optional symptoms and evening check-in, either can be turned off completely • History with day detail, a month calendar, and week-to-week comparison • Patterns: things that showed up together in your own data, with an attribution window you set for your own delayed onset • Reports for your doctor or care team, PDF and CSV, generated on the device • Crash mode: a quieter screen with no prompts or questions, plus a contact to call, your medications, and communication cards to show someone instead of speaking • Siri and Shortcuts for logging an activity, logging rest, or setting your capacity • Appearance, visual comfort and haptic settings • No streaks, no scores, no rankings. A day with nothing logged is just a day. PRIVACY FIRST • Within has no network code, so your data cannot be sent anywhere • No account, no sign-in, no server • No advertising trackers and no analytics • Everything you log stays on your iPhone • Exports are files made on your device, shared only if you choose to share them IMPORTANT Within is a personal pacing and tracking tool. It is not a medical device and does not diagnose, treat, cure or prevent any condition, including ME/CFS, long COVID, POTS, fibromyalgia or any other illness. Capacity is your own estimate of your day, not a measurement. Patterns Within notices are associations in your own logged data, they are not findings, and they never describe a cause. If you are concerned about your health, please consult a qualified healthcare professional. SUBSCRIPTION Within $2.99 / month, auto-renewing.
