Frequently asked questions

Why is Coinbase not supported?

Coinbase's market-data terms do not allow third-party apps to show their data to end users, so it is left out on purpose.

Are there price alerts?

No — and there are no notifications of any kind. The app never requests notification permission. If you want something that pings you when a price moves, TabGreater is the wrong tool, deliberately.

Why does the widget need a foreground service and exact alarms?

Android only lets an app refresh a widget on a reliable schedule from a foreground service, and only exact alarms survive Doze at the cadence you pick. The service shows no notification, and the app never asks for notification permission.

So why does Android list TabGreater as running?

That is the widget refresh service. In the system's active-apps list it appears as "TabGreater live widgets — keeping home-screen prices up to date". It exists only to keep your widgets current, and it never posts a notification.

Where does the "popular pairs" list come from?

From CoinGecko's public market-cap ranking, fetched at most once a day and cached on the device. Stablecoins, fiat-pegged units and wrapped, staked or bridged tokens are filtered out of the top thirty, and the five biggest of what remains become the quick-add chips.

How often do prices actually update?

While the app is open it holds a WebSocket stream to Binance, Gate.io, Kraken and KuCoin; MEXC has no public ticker socket, so it is polled over REST. Separately, a display setting controls how often tiles redraw — that is a redraw rate, not a connection rate. The connections stay live either way.

Can I trade from it?

No. TabGreater never asks for exchange API keys, holds none, and cannot place an order. It shows prices and charts — that is the whole of it. There are no links to exchanges and no referral codes anywhere in the app or on this site.

Is there a light theme?

No. TabGreater is dark only.

Can I move my lists to a new phone?

Yes. Every watchlist exports to a plain JSON file you can read and edit by hand, and import back on another device — either replacing what is there or merging into it.

My widgets stopped updating on Samsung.

One UI's battery management is the usual cause. In the app, Settings → WIDGETS has a checklist; the short version:

1. 1 Settings → Apps → TabGreater → Battery → Unrestricted
2. 2 Battery → Background usage limits → Never sleeping apps → add TabGreater
3. 3 Battery → Background usage limits → Put unused apps to sleep → off
