Personal life
Home apps are the ones you trust with the most personal things: what you spend, your deadlines, your health. Reactive runs them entirely in your browser — no accounts, no profiling, no data leaving the device — and when you want to share them with the people you live with, one invite is enough, encrypted end to end.
The solutions for your home
Piggybank (family budget) and Hearth (household & deadlines) share their data space: an expense entered in Hearth lands in Piggybank’s budget by itself. Vigor tracks health and workouts — those stay yours alone.
How it works at home
Open and use, no sign-up
Suites open in one click and save everything in the browser: the month’s budget, car and boiler deadlines, workouts. No account to create, nothing to install.
Share with the family
A link or a QR and the budget belongs to everyone: each person enters expenses from their own phone and the numbers add up by themselves, in real time, end-to-end encrypted.
Make them yours
Your household’s expense categories, the vet reminder, the chart you want to see: describe it to the AI assistant and the app adapts — and it remains a simple file, yours.
Private by design, whatever the context
Apps run and store data only in the browser; the AI works on the device too; collaboration, if you turn it on, is encrypted end to end. And every app remains a simple text file: readable, exportable, yours.
