Experts recommend maintaining a daily journal to anyone seeking to boost their productivity or even manage their mental health. These free apps will help you write a daily journal on your phone or computer.


Each app takes a different approach to digital journaling, so pick the one that suits your style. Some focus on privacy, others target beginners and time-constrained users. And there’s even an app that turns the concept of a diary on its head by making your journal entries public.

1. Cactus (Web): Guided Journaling for Beginners

Cactus is a mood tracker and journaling app that guides beginners

If you’re new to journaling, Cactus is a good app to start with. It will guide you through the basics of digital journaling while helping you strengthen and improve the core experiences of your daily life.

Once you register for an account, Cactus asks you to check in once a day. There, it will ask you a question based on one of four essential elements: meaning, experience, energy, emotions, relationships. You won’t know the element till you answer the question, in the form of a journal entry.

Questions vary like “who is a person who makes you smile” or “what experiences are you looking forward to this week?” After answering, you’ll get an idea of why the question matters for your mental health. Each entry is a private note to check back later.


At times, Cactus also encourages you to share your notes with people. It’s a nice exercise for gratitude journaling, and it’s easy to share a single note without unloading all your thoughts on that person.

Don’t worry, it’s not like your entire journal is open for anyone. You get to choose which entries to make public and which ones to keep private for your eyes only. The interface is a bit kiddish, using a handwritten script-like font that you’ll have to live with. There’s also a decent text editor for formatting, and you can add images too.

On The Open Diaries public feed, you can browse and read entries from anyone. In our cursory browsing, it seemed like an active social network with people from different parts of the world.

Openly writing a diary might not be everyone’s cup of tea, and we’d advise not sharing personal details with which someone can identify you in real life. As long as you’re careful, it can be therapeutic in a whole new way.
