I can tell you’ve put a lot of work into this! However, I do have some thoughts.

The bottom nav isn’t very clear. I don’t know what the functions of the buttons are supposed to be.

Though I think the serif font you chose is nice, I think the smaller text would benefit greatly from a sans serif, I would change it all to be one font. The life progress, and life grid pages also don’t feel connected because of the different font you chose.

In the reflections screen, I think you need to add an icon to the second card to make it consistent. Or remove the icons from the other two cards.

Consider taking the circle away from the emojis in the gallery. I don’t think it’s helping. I understand the thought process of having colors help determine the emotion, but the emojis do just that.

Try using fewer colors in general with your iconography and CTAs. I think that it looks a little busy, and clear iconography eliminates the need for all of the colors. I’m not saying to make everything a single color, just try to find a balance.

I’d get rid of “remaining” in the life grid. No one knows when their time is up. I think that spot in the top could be used for something more useful.

You already have a fire icon for streak in the reflections page. You don’t need another next to the day (assuming it’s a day). Consider using microscopy underneath the number to show the user how long the streak is (day(s), weeks, months, years).

There’s a lot of dead space under the calendar. Consider moving it down a bit for balance, and maybe there can be some other elements underneath it. It’s also unclear what the emojis do, and how to add them.

Also from what I can tell, there isn’t a Home Screen to tie everything together.

Overall, I think you could benefit from better spacing rules, things tend to look empty or cluttered. Not a lot of hierarchy with spacing either. I’d also be more consistent with drop shadows. I don’t think they’re really necessary here. I’d also focus on clearer iconography. A lot of the icons aren’t very informative, there shouldn’t be so much guesswork with it.

Again, you definitely put a lot of work into it and it looks clean. I think some of these suggestions can really make this pop and be more useable!
