## What is Interval Swim Timer?

Interval Swim is a timer built for swim training. Big buttons that are easy to press with wet hands, large numbers you can read from across the pool and a color for every phase make it ready to use on deck.

■ INTERVAL — set intervals
· Set the swim and rest time, reps and rest after each set (up to 10 sets)
· Set types: Standard, Broken (split each swim into pieces with short rests) and USRPT (many short swims at race pace; tap [Miss] when you miss the time)
· Descend (a faster target on every rep) and Negative split (second half faster)
· A ring chart shows the set's structure in proportion to time
· Save favorite settings as presets and load them in one tap

■ PYRAMID — pyramid training
· Swim more or fewer laps in each step, e.g. 1→5 laps up or 5→1 laps down
· Target times for every lap are calculated from your 1-lap pace and load level (Elite, Masters, Fitness)
· During the workout, a bar fills up toward each lap's target in the current step

■ PACE SWIM — hold your pace
· Alternate 25, 50 or 100 (meters or yards) with double that distance at the same pace
· Set 50 at 0:40 and the 1:20 target for 100 is calculated for you

■ TRAIN — build a workout
· Pick the time (30–90 min), effort, goal (Endurance, Speed, Technique, Mixed) and pool length, and get a full workout from warm-up through the main sets to cool-down
· Ask for another suggestion until you like it, then load it into INTERVAL to adjust it or start right away
· My pace (CSS): estimates your critical swim speed from your best 50 and 100 times and sets the Recovery, Endurance, Threshold and Speed zone paces the workouts use

■ Also included
· The workout screen shows the current and next part of the workout; turn the phone sideways and the numbers fill the screen
· Staggered start: signals for several swimmers leaving a few seconds apart
· Auto-lock on the workout screen, sound and screen flash at every phase change
· Settings for phase colors, font and time format
· 8 languages (switch right in Settings), meters or yards
※ Works on iPhone and iPad

Interval Swim needs no sign-up and collects no personal data. Workouts are built on your device, and all settings stay there.
