When you locate your facility from a drop-down menu in the app – this could be your gym, pool, or workplace smart locker – you will be presented with the smart locker reservation options available to you. Select the location and size of your locker and use your device to open it. Depending on the location parameters these may be free, have time restrictions or have a hire charge which can all be seen and paid through the app.

Verdict
The clearest difference is update cadence: Unlock Devonport at fortnightly against Metra Plus's every 5 weeks. Metra Plus's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 18.2). On price, ads and in-app purchases there is nothing between them.
