Watchlists
Up to 25 lists, 120 pairs each
Up to 25 named lists, 120 pairs each. Four tile sizes — two per row, or full width — each carrying its own sparkline. Drag to reorder, tag a tile with a colour, and export the lot as a JSON file a new phone reads straight back.
Sub-cent prices shrink their zero run: 0.0471501 is 0.000071501.
Charts
Candlestick charts with eleven indicators
Candles, hollow candles, OHLC bars or area, across nine timeframes from one minute to one month. Log or auto scale, fullscreen, and share any chart as a PNG. A fresh chart opens showing volume only — the rest is yours to add.
- MA
- EMA
- BOLL
- SAR
- VOL
- MACD
- RSI
- KDJ
- CCI
- DMI
- OBV
A new chart shows volume only; the rest is opt-in.
Home-screen widgets
Widgets that refresh without a notification
One pair per widget. It drops as a 2×1 and resizes up to 4×2 and beyond, always drawing the same layout. Pick a refresh cadence from live down to every fifteen minutes, choose from eleven background colours and a transparency slider, and tap it to open that pair's chart.
About 1.5 % of the battery a day
Measured over one hour on a Galaxy S23 Ultra with three widgets at the five-minute default. The test harness ships in the repository, so anyone can run it again.
What leaves your device
Your phone talks to the exchanges directly
There is no TabGreater server to send anything to. Your phone asks the exchanges directly, which means they see your IP address and the pairs you watch, under their own terms. Every host it will ever contact is below.
| Host | Why |
|---|---|
| data-api.binance.vision | Prices and candles |
| api.gateio.ws | Prices and candles |
| api.kraken.com | Prices and candles |
| api.kucoin.com | Prices and candles, plus a socket endpoint it hands back at connect time |
| api.mexc.com | Prices and candles — MEXC has no public ticker socket, so it is polled |
| wss://data-stream.binance.vision | Live stream while the app is open |
| wss://ws.kraken.com | Live stream while the app is open |
| api.coingecko.com | The popular-pairs list, at most once a day |
| github.com · ko-fi.com | Only when you tap those two links |
No API keys
The app never asks for them and cannot place an order.
No notification permission
It is never requested, so nothing can ever ping you.
Your data stays on the device
Lists and settings live on the device, and export to a file you control.
Spot markets from five exchanges
