01 Jun — Hyvä kesä ☀️ We are now at around $40k/month.
July: $0 → August: $709 → September: $1,372 → October: $1,689 → November: $1,806 → December: $3,003 → January: $5,754 → February: $7,166 ( 24%) → March: $12,812 ( 78%) → April: $21,041 ( 64%) → May: $40,239 ( 91%)
But this time, I want to focus on another side of the business: expenses and tax.
Again, this month we continued scaling Google Ads. Now Google app spend is around $22k/month, which is around $750/day.
Then we have Apple App Store and Google Play Store fees, which are 15% for renewals, so that is around $6k.
Then we have VAT for each country, which is around 0–25%, depending on the country. For us, it is around $2k because most of our revenue comes from the USA, where VAT is zero.
Then there are other costs like RevenueCat, around $400, software purchases, mainly lifetime deals from AppSumo, around $1k, and some other things around $2k.
We also need to pay income tax in Finland, which I am not sure about yet, but it might be around 20%.
Then there is YEL, including pension, around 24.40%. And if you plan to hire someone, it will often cost around $2k–$4k/month in Finland.
So be prepared for all these costs.
Right now, Google Ads is our main way to scale, and ROAS is around 100%. I think this is okay because it helps with app ranking in the store.
Now, most users are on yearly subscriptions, so hopefully we are still in business next year. Normally, around 25–50% of users still renew, so it can compound next year.
I still go to the swimming pool around 3 times a week plan to do more running, gym next month.
On the building side, I mostly focused on small Android bugs this month. These bugs are annoying because normally I cannot reproduce them myself, and they only happen on a user’s phone. So it is time-consuming to fix them.
Also this month, I asked one of my friends to test TikTok with me.
What’s next:
I will spend some time learning TikTok with my friend.
I think Google Ads is okay now. I will still slowly increase it depending on the ROAS.
I also plan to try Apple Ads. Apple Ads recently added a second slot for ads in the App Store, so the price may be cheaper than before. Let’s give it a try again.
I made $50,210 in May 2026.
