ARTEMIS App
Read full descriptionHide full description
This app has been designed by researchers at the University of Oxford to help you manage your weight as part of the Adults Regulating Their weight Everyday with Mobile Internet Support (ARTEMIS) study. The idea behind the app: there is rarely a βone size fits allβ solution to weight loss. We know from previous research that different approaches work for different people. The idea of the app is to help you try out several weight loss actions (e.g. brisk walking or cutting out snacks) and learn from your successes and failures. Itβs like youβre experimenting on yourself! Every time you try out a new action, you can monitor your weight and gain a clue about whether the action works for you. You can then use this information to decide whether you want to continue doing this action or try another. We will support you to build a set of personalised actions that you have tested for yourself and that work for you β your very own βAction Toolboxβ. You can then use this toolbox as a matter of usual practice to help control your weight going forwards.

'tend' is a gentle daily companion for your mental wellbeing. Built around evidence-based techniques, it helps you build the small habits that make the hard days a little easier, one check-in at a time. Daily Check-In: Start each day with a gentle mood check-in. A few taps and a short note is all it takes. Over time your check-ins become a private record of how you have really been, showing you patterns you might not have noticed on your own. Grow: Your 8-Week Program: A structured program to build real, lasting mental wellbeing skills. Each week introduces one technique through a short intro, a guided exercise, and a real-world experiment to try in your own life. Complete exercises, write reflections, and unlock the next week at your own pace. Set personal goals alongside your program and track them as you go. Habit Tracker: Small actions done consistently are what actually move the needle. Build your own habits, track streaks, and link them to your goals. Your first three habits are free! Evidence-Based Toolkit: β’ Thought records - challenge anxious or unhelpful thinking, step by step β’ Grounding exercises - come back to the present moment β’ Worry postpone - schedule your worries for later so they do not take over now β’ Breathing exercises - slow down and reset β’ Guided Relaxation - Progressive Muscle Relaxation with a calm, guided voice. Work through each muscle group at your own pace. β’ Stability Plan - build your personal safety net for the moments things get hard. β’ Self-compassion - a guided exercise to meet yourself with kindness, even on the hardest days β’ Gratitude - a simple daily practice that trains your brain to notice what is good, not just what is hard Journal: A private space to write freely. No prompts, no structure, no rules. Everything stays on your device. Progress: A private record of everything you have done: check-ins, thought records, worry postpones, and more. Patterns emerge when you look back, and looking back matters! Meet Bisous! Bisous is a little dog with a lot of warmth. She shows up every day inside 'tend' to check in, adapts to how you are feeling, and reminds you that someone is in your corner. She celebrates the good days. She sits quietly with you through the hard ones. A note: 'tend' your mind is not a replacement for professional support. If you are struggling, please reach out to a therapist, your GP, or a crisis line in your country. Legal: Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
