Just applied for the Apple small business program

Do you automatically get accepted as long as you meet the requirements?

FIRST TRIAL STARTED OMG

One day after I released the paywall

This is a user that's been using the app for over a year

This is such a good feeling

My retention is currently the best it's ever been

This is the result of the last 2 months of iteration

If this remains like this I will be so happy

Damn I vibe coded too hard and shipped a bug to prod

Minor one but still hurts: forgot to add an analytics event for the paywall

This means waiting for app review again

Maybe this is a good reason to add OTA updates

Since I've added monster fighting to Habit Slayer I've noticed a bump in retention

These are the recent values of my D1 retention, averaging 35%+

Most of these stick all the way through D7, so the app definitely clicks for them

Analytics is such an important tool

I honestly think I found the best gamification system for productivity and self-care

You fight monsters by doing your habits

When you do a habit, you hit the monster, and it hits you back

Truly the definition of turning your life into an adventure

One of the best signs you've got a good app is app store reviews

The people reviewing are usually very strict

So if you have a good rating, it means you're onto something

Habit Slayer is currently sitting at 4.7

My biggest problem right now is distribution

I have an app deployed to the app stores with good retention and reviews

The app concept is proven, I just need more people to see it

Which unfortunately, is the hardest part for me

Day 8 of building an app to $10k MRR

Next steps, send to app stores!

If you're posting on TikTok with captions, pls don't use an Android

The result will look like this (it looked fine while posting)

It's insane how bad these apps are for Android

Really strong signals that my core app feature is resonating

63%+ of users are starting a combat and 50% are defeating a monster

These numbers have been slowly averaging upwards

Views slowly going up on very low effort videos

Didn't know marketing your app can be this easy

The video is literally a 6 second screenshot with a caption and a sound

I can make infinite of these

This is the diamond store. You can buy diamonds to then buy cosmetic items for your character

Could be the prices, could be the items, could be the copy, or could be something else idk

Will investigate and report back

So far, conversions on my app's in-app purchases are 0%

Only 21% even opened the diamond store, and of those only 2 have tapped to initiate a purchase

Both didn't convert sadly

Need to work on this, but this is not the priority rn. Subscriptions are
