Small apps that do one thing properly.
We build focused tools for people who care about how things work. No ads, no accounts, no tracking — just software that does what it says, and tells you the truth about it.
aCelery
Build your own apps · Android & iOS
A pocket workshop for small, personal apps. Write a few JavaScript files on your phone and tap Run — or just describe the app you want in plain words and let an AI assistant build it for you. Real database, forms, tables and charts built in. Works offline.

Software that respects you
Every app we ship follows the same few rules.
No ads, no accounts
Install it and use it. Nothing to sign up for, nothing selling your attention.
Your data stays yours
No analytics and no data collection. What you make and play stays on your device.
Honest by design
Our apps tell you exactly what they're doing — and what they won't do — in plain language.
Works without the cloud
Built to run on your own device and your own network, so they keep working when the internet doesn't.
Questions, ideas or feedback?
We read every message. Whether it's a bug, a DAC that behaves strangely, or an app you built with aCelery, we'd love to hear from you.
