GitThe rest run inside client companies and are not public. Whatever is open is linked.
Turns Instagram comments and direct messages into set flows: a keyword starts the reply, and one inbox keeps every thread in a single place. For creators and small teams who would rather not type each reply themselves.
The inside of a creator agency: record creators, sort them with tags, reach out and take them through onboarding. Plus the routines the team runs internally.
Run Minecraft bots from the browser: keep accounts online, manage servers, bill subscriptions.
A point of sale for everyday shop work: take orders, keep the records straight, and every change lands on all devices at once.
Scan barcodes and QR codes in the warehouse. Stocktaking, sign in and stock moves happen at the shelf instead of later at a desk.
An Android app for a business client, with Microsoft sign in and access to the company APIs.
Jobs and workflows on the phone: hand out tasks and keep customer data with you.
Store checks on the phone: work through the list, attach photos, send the report.
Log blood pressure, pulse and weight. The readings stay on the device and export as PDF or CSV.
