Pearl Hub is your all-in-one companion for the Pearl ($PRL) network — a self-custody wallet, a read-only mining-pool monitor and a profit calculator in one app.

Pearl Hub does not mine. No mining or hashing ever runs on your phone — the app only reads public statistics published by mining pools, for hardware you run elsewhere.

SELF-CUSTODY WALLET
• Your keys never leave your device — the recovery phrase is encrypted with a key held in the Android Keystore and never uploaded.
• Send & receive $PRL in seconds, with QR codes and an address book.
• Your fingerprint, face or screen lock unlocks the wallet and guards your recovery phrase.

POOL MONITOR (READ-ONLY)
• Follow the hardware you already run elsewhere, by public address, across pools (Kryptex, AlphaPool, Lucky Pool, HeroMiners, Pearl Fortune) — live & 24h hashrate, per-worker status, pending/paid rewards, and real on-chain income.
• Compare every Pearl pool: fee, blocks, yield per PH and hashrate share — no address needed.

PROFIT CALCULATOR
• Compare GPUs by hashrate, efficiency and break-even rent; estimate daily / 30 / 90-day net profit from electricity price, pool fee and difficulty. It is arithmetic on the numbers you enter.

PEARL HUB PRO (optional one-time purchase)
• Price alerts: a push notification when PRL reaches your target price or moves sharply, even while the app is closed.
• Offline alerts: a push once a worker of yours has been offline for the time you choose (10 minutes to 2 hours), an optional reminder if it is still offline later, and another push when it is back online. Our server reads the pool's public statistics; nothing runs on your device.
• Live PRL price on the lock screen, and home-screen widgets for price, pools and your wallet.

EVERYTHING SYNCED
• Pro comes back with your Google Play account when you reinstall or switch phones.
• Optional email account (Pro): sync your setup, contacts and alerts with your other devices and the Pearl Hub web version. Recovery phrases and private keys never leave your device.
