Under the hood
We didn’t outsource the hard part. Finabase is our in-house real-time finance platform — live quotes, FX rates, and deep historical series streamed over a low-latency backend. It’s what makes Stock Master tick and Currency stream. And it’s an investing workbench in its own right: interactive charts, live heatmaps, screeners, alerts, and AI-driven market insights, right in your browser.

How we build
Finance and family data are the most personal data there is. Every Apponance app is built on three promises that don’t change from app to app.
Financial records, location histories, family logs, and private documents deserve restraint. Our apps start local, encrypt network traffic, and never turn your personal data into advertising inventory.
When an app spans devices, the experience follows you: capture or log on your phone, continue on the web, and keep the same private data available wherever the product supports it.
No bloated mega-apps. Each Apponance app does one job exceptionally well — sending an invoice, classifying a drive, saving a scan, or starting a feed timer with as little friction as possible.
What our users say
Real reviews from real users, pulled straight from our public store listings.
“Let’s be realistic!”
There are plenty of stock market apps one could choose. Yet Stock Master, hands down, offers the widest range of data and potential stock analysis at a baseline level any non-broker needs. Company financials, charts, news… If you want to quickly consider a full set of data in real time, on the fly, with ease — look no further.

“Excellent graphs”
Not just the graphical quality, it is also the content of the graphs — stock performance vs indicators. I use a professional charting app at home, but this on my iPhone when remote allows me to see stocks clearly and simply, despite the small screen.

“Great for VPN users”
I’ve downloaded several apps to do exactly this, and this app does it perfectly where most (all?) others fall short. Great to quickly check connectivity in general, and VPN connection and geolocation specifically. Many other features as well.

“Great app. Highly recommended.”
I found it very easy to use and very helpful. Highly recommend this app if you are doing small business. It provides powerful template customization. The PDF report is very useful too. Just have a try and I think you are going to like it.
