Swim PB is used to keep a historical record of a swimmer's (or a group of swimmers') times.

When a time for an event (e.g. 50 freestyle, Short Course Metres) is entered for a swimmer, the app compares the time to the one previously stored for this event and informs the user if the time is faster, slower or no time exists for the event.

In addition to the list of all a swimmer's times, a list of the swimmer's current Personal Best times for all events can be shown (these times can also be sent out via email from the app).

Plots of a swimmer's results over time can also be displayed.

Targets can also be added (via the 'Swimmers' menu - 'Show Targets'). An example target might be 'IAG div 2 male age 12-13' which would contain the target times for all events for Irish Age Group, division 2, male ages 12-13. The required target for a swimmer would then be selected from a list in the 'Personal Best Times' view. For each event in the list, the relevant time would be shown from the target, along with the difference between the PB time and the required time for that event.

List items (from the 'Swimmers', 'Targets' and associated times) can be re-ordered and deleted using the 'edit' button - to delete a swimmer or time, click the red icon to the left of the item, to drag a swimmer or time to another location in the list use the 'drag' bar to the right of the item.

Individual times can be modified by selecting the required time from the list (without needing to select the 'Edit' button).
