Introducing: End-to-end Encryption

Grid Diary is more than just a journaling app, but an everyday personal development system.

When it comes to personal growth, we want it all:

• Practicing mindfulness & self-love
• Building morning & evening routines
• Improving personal health & wellbeing
• Cultivating self-care habits
• Relieving stress and anxiety by changing your thought patterns (Cognitive Behavioral Therapy)
• Acquiring new skills
• Increasing productivity
• Maintaining good relationships
• Boosting creativity

and the list goes on.

We believe that personal development is not singular-focused, but rather, a holistic process.

In Grid Diary, you can fit all the desired areas of development in just one system, and reflect on them on a daily, weekly, monthly, and yearly basis.

# Feature Highlights

• Prompted Journaling: Guided Self-Reflections
Instead of starting on a blank page, prompt yourself with either the questions from our library or customized questions. This inspires deep self-reflection and saves you writers’ block.

• Unique Grid Format: Simple yet Holistic
Fit all the things that matter to you on one single page, in a grid format. This is a simple technique that helps you build a holistic personal development system. You can customize the grid layout to your own liking.

• Mandala Layout: Journal like a Mind Map
This 9-grid layout with one fixed center is inspired by the art of Mandala, a geometric pattern that represents the organizational structure of life and its relation to the cosmos. It makes journaling more intuitive and compatible with how our mind works- like a mind map.

• Day/week/month/year Dimension: Build Your Own Ritual
Rituals help us set anchors in time, a force that seems so uncontrollable yet makes up our whole life experiences. Build your own ritual and choose your own rhythm to plan, act, and review on a daily, weekly, monthly, or yearly basis.

• Compatible with Different Journal Methods
Do you follow the method of morning diary, success diary, manifestation journal, or bullet journal? With extensive flexibility, Grid Diary makes it easy for you to practice whatever method works for you.

Importance of Reflection

Since becoming a teacher I have reflected a lot as an educator in order to improve my own teaching style and model for my students what it means to put effort towards improving. Now having kids of my own reflecting on how fast they actually grow and develop becoming the humans beings they will be. Grid Classic 2 allows me to reflect on how fast they are growing up, they seem like new people every week. GC2 allows me to change topics as different things become more pertinent in raising them and their own interests change, and when ready I can share with them all of my joys, mistakes, worries, fears, pride, and resilience in parenting and enjoying who they are and are becoming. You’ve made a great app that is user friendly and incorporates so much. Thank you for your efforts. I cant wait to look back years down the road, shake my head and laugh at tragic comedy that is day to day parenting.

I Want To Love It

Don't get me wrong, I LOVE everything about this app, and even pay the premium membership. The only addition that would be super cool to see would be some place you could have a checklist of things that repeat to each day on a daily grid or something. That would be the ultimate app for me, and I would be a forever customer, as long as you can fix one thing:

I do a lot of memory journaling for my kids to have one day, so I use this a lot to quickly write down my thoughts and happenings throughout the day until I can spend the time to make it "pretty" in my physical journal.

But you guuuuyyys. The syncing has to get better. Sometimes I will input things on my phone, sometimes my MacBook. And a lot of the time they don't crossover and once and a while disappear completely. These are my memories! My kids milestones! This can't be happening. I will be a forever yearly premium customer if I feel confident my memories aren't going to be lost... and right now I'm not confident. It's so frustrating!

Unique, Customizable, Game-Changing App!!!

I’m only able to edit the review I have already made, but in doing so, I am “upping” my rating to 5 stars. There is truly no comparable application anywhere that even approaches the ease of use, abundant (and not bloated) features, with the number of customization tools available as Grid Diary 2! Anyone who uses this app can surely tell that there is a lot of love and care in its design, maintenance, and extension...I talk this app up to everyone I know who would be interested. There is literally simply nothing like it out there, and it truly is a game changer. 2 minor features I’d still love to see:
- In the “Timeline” context, using the filter function, the weather stickers and emoji stickers are not multi-select, while the flags are. I would think that if a user wanted to select all entries where they were either upset OR sad OR mad, they would be able to do so.
- A desktop version of the application and cross platform synch would be awesome as well. :)
All in all, this is a great app...well worth the meager price of subscription, and I certainly appreciate your efforts in delivering this kind of quality mobile application. It is truly a credit to your creativity, care, and tenacity to be able to produce something this amazing!
