Small apps that respect your privacy and get out of your way.
Tropic Dev Worx builds clean, reliable Android tools — from a floating clipboard for people who answer the same message all day to an offline checkbook register. Just tools that work.
Our apps
Three tools, one philosophy
Each one solves a specific, ordinary problem — and keeps your data on your device while it does.
QuickPad
Your best replies, one tap away — floating over any app.
QuickPad puts a floating clipboard on top of whatever you are working in. Open it from a side tab, grab the reply you need, and paste it without switching apps.

Dollar Logger
A clean, offline checkbook register.
Track debits, credits, transfers and balances in a register that behaves the way a paper checkbook should — fast, quiet and entirely on your device.

PinPointed
Wherever you go, remember it.
Mark interesting places in one tap while you are on the move — then find your way back to them later. Driving for work, exploring a new town, or saving somewhere for next time.

Privacy is the default, not a setting
We are a small studio, which means we do not need your data to make the numbers work.
Your data stays yours
No accounts to create, no profile to build, no quiet syncing in the background. What you put in the app stays on your phone.
Offline by default
These apps work on a plane, in a basement, and at a campsite with one bar. Connectivity is a bonus, never a requirement.
Small on purpose
Every app does one job properly instead of ten jobs badly. Fewer settings, fewer surprises, less to learn.
Guides
Common ways people use QuickPad
If you answer the same questions every day, one of these is probably your situation.
Quick replies for Android, in one tap
Save time with canned replies and a floating overlay that works over any app — built for Airbnb hosts, Turo, Marketplace, support and sales.

The QuickPad overlay sits above any app so you can copy templates without switching screens — fast access while you chat, list items, or support customers.

Ready-to-paste templates for Airbnb and VRBO, Turo vehicle rentals, and Facebook Marketplace — kept one tap away by the QuickPad floating overlay.

We read everything that comes through. Feature requests from people who actually use the apps are how most of this gets built.
