Pocket CycleTech helps you track the usage of physical parts and also allows you to record when you did service tasks. When you record a service action on your bike, whether you did it or a cycle tech did, you can record replacement parts. The system can then match dates of these events to rides and give you an accurate record of the mileage and time served by components. The app also allows you to record recurring tasks so you can track the maintenance of the bike, so you can record how often you lubricate the bike, or recharge the battery, or check the wear on brakes or chain. A maintenance event always consists of an action (which is a list of tasks) but using parts is optional.
For example, a service consists of checking brakes, gears, cleaning and lubricating the bike, amongst other tasks. You can select the action "Service", and it will note those actions have been done. Having checked the brakes, you may decide to change the pads, you simply remove the old pads and add the new pads with a couple of touches. You don't need a new action of "Change pads" as it is implicit, and the system has all the information it needs to track the pad wear and tear.
This allows you to list all thework that has been done on your bike
Note: to keep the system easy to use, the system allows you to add or remove parts at any time in the past. This does mean that there are a couple of scenarios which are difficult to handle. Say you had a derailleur on your bike which you had scavanged from another bike. You added it to the current bike but then realised it was not showing its true wear and tear as it had been on another bike which you had records for. So if you then add the derailleur to the old bike in the past, PocketCycleTech will then have a part on two bikes. It will allow you to do this, but it will warn you that it is nonsense. You can then fix the issue by adding another maintenance event to take the part off the original bike before it is used on the current bike.
A second difficult scenario is that you realise that you made a mistake and wanted to show a part was added at a different time, but you already have a record of removing it from the bike. The app will allow you to cancel the addition of the part, and will prompt you to delete the part removal at the future event.
If you get the parts in a mess, not to worry, simply correct the events to how things actually happened and the app will be fine. Use the item usage screen to check for any errors.
