About

LOCKnGO

Features
Read full description

LOCKnGO turns your phone into the key for a network of smart bike racks. FIND — Open the map and instantly see nearby racks with live availability, so you never walk to a full rack. Save your favourite locations and jump back to places you park often. LOCK — Roll up, slide your bike in, and secure it from the app in seconds. Your phone talks directly to the smart lock over Bluetooth — no fumbling with keys or combinations. GO — Your session runs while you're away. The map remembers where your bike is parked, highlights it, and gives you one-tap walking directions back to it. UNLOCK — Slide to unlock and ride off. LOCKnGO works even when the network doesn't: your phone and the lock talk directly over Bluetooth, so a dead zone never strands your bike. BUILT TO DETER THEFT Unlike a cable looped around a wheel, LOCKnGO racks lock a motorized deadbolt through your bike's frame and anchor it to a fixed rack. Tamper detection is built into every lock, and your session keeps watch until you — and only you — unlock from your phone. No key to lose, no combination to guess, no cable to cut. FEATURES • Live map with real-time rack availability • Favourites and recent parking locations • One-tap return to your active parking session • Locate your parked bike on the map, with walking directions • Works offline — Bluetooth-direct locking and unlocking • Session history and secure account LOCKnGO is operated by Green Spirit Technologies Inc.

Verdict

The call

The clearest difference is in-app purchases: LOCKnGO at none against Currency's 3. LOCKnGO also leads on ads (none vs shown). Currency's advantage is chart position (#100 vs unranked) and device support (4 vs 2). On price, update cadence and iOS requirement there is nothing between them.
