Example day: 6-day streak, ₦1,400 of today's ₦2,000 goal. Try a scenario on the right.

Press = act · Hold = talk

Left: Talk (hold) · Lock | Right: Wheel ▲▼ · Back
Main button: press to act · hold 1 s to pay

Earning feels like a game

Streaks, a daily goal ring and a payout moment worth waiting for.

Money at your fingertips

Balance at a glance, payout alerts, and earnings you can spend straight away.

AI that actually helps

Hold the button and ask. It talks back in your language.

Voice:

Local-language lines are sample phrasing for the concept and should be checked by native speakers.

Pro edition: its own 4G

A built-in eSIM keeps it online without the phone, and it can share that 4G as a hotspot.

Pro comes with a wireless charging pad (Qi). Hotspot suits one or two devices (Cat-1 4G, up to about 10 Mbps) and uses the most battery. Prices are examples.

Lives on your desk all day

Clock, weather and reminders, so it never ends up in a drawer.

Wear it or clip it

A metal loop on top takes a neck strap, keyring or bag clip, and the name tag is engraved with the owner's name.
