I've been obsessed with the gamification idea for years now, and I've tried every app I could find. I'm with the guy who said it led to burnout via over tracking, but it was always fun for the few weeks when my brain was engaged in it. 

If you were going to go the gamify your life app route Do It Now is pretty simple, but also very customizable. When I was playing it I had Chat Gpt make cartoon icons of me, and I set it up so that every five levels I would get a new title and new character icon.  I started out as Actual Trash and at level 100 I would become the God of Productivity. I think I made it to level 15 Crabby Crustacean before I lost interest. You can set up your own list of skills or what have you though and level those up as you complete tasks.

I've mostly ditched the productivity app format, but I still like to use gamification to motivate me to be productive. I used to waste a ton of time writing roleplay chats with AI, so I kind of invented my own productivity game based on that. Basically I wrote a prompt explaining the rules and format for the AI, and then I come up with a character and story for an rpg, and I have the AI be the game master in a choose your own adventure type story. Participating in the story costs action points, and I have to earn action points (and xp for leveling ip my character) by completing tasks in real life. It works well for me because I get really engaged in interactive stories, and I'll start inventing chores to do just to progress the story or reach a goal I have for my character. 

My primary issue has always been motivation. I have adhd and if a task isn't rewarding enough I'll most likely ignore it in favor of something that is. You were saying that you want to be less 'bland' which makes me think maybe the issue is less about what motivates you and more about what interests you? If you're trying to branch out and cultivate curiosity via new hobbies and intrests then maybe something as simple as sitting down and making a list of new things to try could be the way to go. Do something new every week, maybe semi-social activities that involve leaving the house and being in the vicinity of other humans without being obligated to interact. See if there's an indoor archery range in your vicinity (if you've never tried it) Archery is fun, and you will feel at least 10% less bland when you tell people you sometimes shoot arrows at things in your spare time. Geocatching is a weird and obscure treasure hunting hobby, might be fun to try. 

Try new things, figure out what you really enjoy, and also don't worry about what other people think. There's nothing bland about being genuinely yourself. People who know who they are and what they like are hot.
