Do more. Achieve anything. Grow's scientifically backed habit formation method is designed with everything you need to stay focused and crush your goals. BUILD YOUR MENTAL ASSETS Good habits increase motivation, productivity and persistence to achieve long-term goals.

This app helps you laying the mental bricks. PSYCHOMETRIC HABIT BUILDING GROW is the first and only psychometric habit building app* - not just a habit tracker. It helps you define your habits and shows your progress. This is how it works: 1. DEFINE: GROW guides you through an optimized habit definition process 2. MEASURE: GROW asks you questions about your habit after each repetition (psychometric measurement) 3. FEEDBACK: GROW shows your progress by showing you stats on how psychologically strong your habit has become Optionally: 4. OPTIMIZE: GROW can analyze your stats and show you weak spots in your habit and how to optimize them (subscription function) LEARN LANGUAGES, BE MORE PRODUCTIVE, STUDY EFFECTIVELY - YOUR CHOICE GROW works best for habits that are can be done in 3-60 minutes. Use it for building study habits, learning languages, writing, making money, working, practicing, fitness - whatever you want to achieve, you can build a habit around that. STUDY CONFIRMS: +150% HABIT STRENGTH, -50% MOTIVATIONAL PROBLEMS... ...after 42 habit repetitions with GROW. A psychological study with 100 German college students building new(!) study habits proved the effect of psychometric habit building with GROW. STATISTICS It's very rewarding watching these stats develop over time - believe me. AUTOMATICITY: Shows you how strong your habit has already become (habit strength).

Trust it blindly and go with it. It’s brilliant. ### 5/5 — Super App um Gewohnheiten aufzubauen! 💪🏼 *2019-07-17, version 1.1.5* Ich benutze die App nun seit ein paar Wochen jeden Tag und sie hat mir sehr dabei geholfen meine Fitnessgewohnheit mit dem frühen Aufstehen zu kombinieren. Ich bin super begeistert 🎉 Seit einigen Tagen habe ich eine zweite Gewohnheit zur gesunden Ernährung hinzugefügt und ich feile bereits an der nächsten zum Lernverhalten 📚 ### 5/5 — Very intuitive app with useful metrics *2019-04-16, version 1.1.4* This app is very user friendly, well thought out and keeps track of the science behind forming a habit. I've been using it for about a week now and it already motivates me to be able to consistently log my daily session. ### 5/5 — Lifestyle Changer *2019-03-03, version 1.1.3* This app has really helped add things to my daily routine. It has a lot of tracking stats that really motivate you by showing you your progress. Free version gives you almost everything you need, so no reason not to try it out! ### 5/5 — Contextual Habits *2019-02-23, version 1.1.3* I’ve been using Grow for nine days and found it to be very useful. I have used it to incorporate an additional habit into my routine, but kind of wish I had known about the app when beginning my other tasks as well. When you create a habit, Grow will ask a serious of questions, similar to the SMART Goal setting technique, if you are familiar with that. As you complete repetitions, the app asks you to answer questions related to what you first submitted and provides data on that particular habit. This is a nice feature I have yet to see in habit/task apps. However, I am also left wondering which questions affect what data. Perhaps it’s intentional that the user isn’t told that ‘Question A’ will affect ‘Metric B’ in order to keep a more accurate and objective presentation of feedback, but that is about my only critique. I’m planning to add another habit into my routine and will use Grow to do so! ### 5/5 — 100% recommend *2019-02-08* I’ve struggled to stick to goals my whole life - relying on motivation rather than discipline. Within a month of using this app I’ve built habits which have helped move me towards reaching my goals. Without even thinking about it I work towards my goal on a daily basis. I would 100% recommend this app to anyone who has issues building habits or constructively working towards goals. **Developer response:** 100% amazed by your review! Thank you🙏🏻. Really happy to hear that you could use it to work towards your goals 💪🏼😁 ### 5/5 — Best Habit builder *2019-02-03, version 1.1.2* I have been trying to build new habits for almost 3-4 years and have never come across an app better than this. It’s based on the latest science of habit building plus you can easily enter data as well as monitor your streak. This is the first time any app has helped me get past January with my new year Habit resolutions. ### 5/5 — Great app to keep you going *2019-01-30* Grow is a great app to motivate you to maintain a new habit, particularly during the most difficult and crucial time: the beginning. At this stage it’s about consistency and Grow has been a little voice to prod me in the right direction. It’s reminders, graphs, ease of use and visual appearance all combine well make you want to build your habit. **Developer response:** Thank you for the great review! Happy to hear that it worked out for you 📈👌🏻😁 ### 5/5 — Super App ! *2018-11-16, version 1.0.3* Einfach nur vorbildlich ! So sollte eine App sein , die frisst keine Zeit sondern bringt einen voran und hilft einen seine persönliche Ziele zu erreichen ! Sehr einfach und verständlicher Aufbau . Kann ich nur empfehlen 👍🏽 ### 5/5 — . *2018-11-16, version 1.0.2* Never thought about habits in a scientific way ... thought either you have the willpower or discipline or not ... but learned some new stuff here ... ## Frequently asked questions about Grow ### How does Grow's psychometric habit building work?
