Spark · The physical key for your focus.

Spark is a small Bluetooth device that makes a focus zone. Choose your apps in the free app, pair your phone once, and put Spark where focus should happen — the study desk, the office desk, the bedside table, or your bag. Bring your phone near it and your distracting apps lock by themselves, within moments: no tap, no button, nothing to remember to start. Move out of range and they come back. Its range covers about a room, and more in open spaces; walls, floors and furniture reduce it. Switching Bluetooth off doesn’t unlock anything. Calls always get through.

• Deep work — The big ones plus the sneaky ones. Two hours, no exceptions.
• Study — Everything that isn't notes, reference, or a calculator.
• Family time — Just the three that keep pulling you out of the room.
• Sleep — From an hour before bed until the alarm goes off.

Same device, same free app, same focus zone. The only difference is how many phones one Spark pairs with. A phone that isn't paired with a Spark is never affected, whichever edition it is.

• Spark Home · up to 5 phones. For you and your family. Study desk, bedside, dinner table, your bag.
• Spark Business · unlimited phones. For offices, classrooms and shared spaces. Meeting room, office floor, coaching class, library, reading room.

If you need more than 5 phones on one Spark, choose Spark Business.

Spark works with an iPhone on iOS 17 or later, or an Android phone on Android 12 or later. Nothing more is needed.

The Spark app is free, with no subscription, and it isn't in the App Store or Google Play yet — the links will appear on the download page when the listings go live. Pairing a Spark needs a free account and an internet connection, once; after that, locking and unlocking work offline. What each platform lets Spark enforce differs, and the download page sets out both.

• Dispatch. Within 7 days of your payment clearing. A colour on preorder ships by the date shown beside it instead. Once it leaves, the courier and tracking number appear on your order page.
• Delivery. Free, anywhere in India our courier partners deliver to — typically a further 3–7 working days after dispatch, depending on your PIN code.
• Cancelling. Any order, preorders included, until it is handed to the courier, for a full refund to the account you paid from. There are no change-of-mind returns after dispatch.
• Damaged or not working. Tell us within 7 days of delivery, with a photo, and we replace it free, shipping included.
• Warranty. A 1-year warranty against manufacturing defects. Not covered: batteries, physical damage, water damage and loss.

The binding terms are the shipping policy and the refund and cancellation policy.

All of them are things worth knowing before you spend anything — including the ones that tell you when a rival, or your phone's own free tools, will do.

• How it works — the four steps, and what setup actually involves.
• Pricing — the commercial model: free app, one-time device, no subscription, and the two editions side by side.
• Why a physical device — why the place should decide, not your willpower, and the honest limits of it.
• Spark vs Brick — how the two devices differ, and when Brick is the better buy.
• How it compares — Opal, Freedom, Screen Time and the rest, including when to buy theirs instead.
• How to block apps on iPhone and on Android — every method, the free ones included.
• The free app— no subscription, and it needs a paired Spark to lock. It isn't in the App Store or Google Play yet.
