Small, focused apps from a one-person company
SleepyBytes is Aivars Meijers, building iPhone, Apple Watch, and Mac apps since 2014. No growth team, no dark patterns: each app does one job well, keeps your data on your device, and gets better a little every week. The whole journey is documented in public on YouTube.

About
Why SleepyBytes exists
SleepyBytes started as a side project in 2014 and became the home for every app Aivars ships. The recipe has not changed: find a specific problem (holding your breath longer, remembering what a ride felt like, calming a racing mind), build the smallest honest tool that solves it, and charge fairly for the parts that cost money to run.
The company is deliberately one person. That means slower feature lists but direct answers: every support email lands with the developer, and every review gets read.
The build-in-public side, revenue numbers, experiments, and lessons, lives on aivarsmeijers.com and the YouTube channel.
