02 — How we build
From sketch to app store.
Every Ecodaa app follows the same path: analyzing the problem, designing, building and putting it to work in the lives of the people who use it.
- 1
Analyze
We start from the real problem of the people who will use it: what gets in their way today and what an app needs to solve.
- 2
Design
Simple screens and flows, designed for phone and desktop, before any code is written.
- 3
Build
Short, tested iterations, with care for speed and data privacy.
- 4
Ship
Package, store listings, copy and privacy policy. After launch, the apps keep improving.
03 — Why Ecodaa
Built to last and to respect you.
Support straight from the developer
No middlemen and no call center: you email the person who builds the app.
Your data, on your device
Whenever possible, the app keeps your information on the device itself: more privacy, it works offline and it does not need a server to open.
Real apps, not prototypes
We maintain apps with licensing, privacy policies and support. We know what each store and each user expects.
Always improving
The apps get improvements from real-world use, with new versions and fixes.
04 — FAQ
What people usually ask us.
What does Ecodaa do?
We build and maintain desktop and mobile apps: Harpia Journal (trading journal, Windows), Kakeibow (Kakebo-method budgeting, Android), ECOStock (stock counting, Android), StepRisk (Chrome extension) and ECOCaixa (point of sale). Dia Católico (Catholic prayer, Android, in Portuguese) is coming soon. See them all in products.
Which apps can I use today?
StepRisk (Chrome extension), Harpia Journal (Windows, in Portuguese), Kakeibow, ECOStock and ECOCompras (Android, on Google Play) are available now. For the ones not out yet, on each product page you can ask to be notified by email when it launches.
Do the apps work offline?
Most of them, yes. Kakeibow, ECOStock and ECOCaixa keep their data on the phone, and Harpia Journal keeps it on the computer. Only the features that really need the internet depend on it, such as payments, licensing or market quotes.
Where is my data stored?
Whenever possible, on your own device, with no account and no Ecodaa server. Each app has its own privacy policy: Harpia, Kakeibow, ECOStock, ECOCompras and StepRisk.
Is there an iPhone version?
Not today. Our apps are for Android, Windows and Chrome.
How do I reach support for one of the apps?
By email at suporte@ecodaa.com. Tell us which app you use and what happened. We reply in English or Portuguese.
