Give your simulator superpowers

RocketSim: An Essential Developer Tool
as recommended by Apple

Issue 139
Nov 01, 2022

Why you shouldn't always believe what others have to say.

It's the early days of RocketSim; I just developed version 2.0.0 and introduced the first In-App Purchase. Many great responses got shadowed by a single adverse reaction: "People will never pay for such an app."

The same happened during the first launch of Stock Analyzer. It's hard to ignore negative thoughts, even though you might have plenty of positive messages to read.

Yesterday I reached my year Monthly Recurring Revenue (MRR) goal of €1000 two months early. I never stopped believing in my ideas and my apps. Instead, I raised the bar and became more motivated to prove my expectations.

There will always be reasons for you to derail from your goal, but it's always up to you to give up on an idea. I'm setting new targets for 2023: reaching €3000 MRR, and I'm going to prove to everyone this is doable 💪🏼

Enjoy this week's SwiftLee Weekly!
