Rep Counter App for Athletic Training on Android

Decide what a rep means before you count it

The most common reason training logs become useless is inconsistency in the unit, not missing data. If one coach logs a "rep" as a single jump and another logs it as a set of five, the totals cannot be compared. Agree on the definitions first and write them into the tag description.

Some workable conventions:

• Plyometrics: one ground contact equals one rep. Box jumps, bounds and hops are counted per contact.
• Sprints and starts: one effort at full intent equals one rep. Walk-backs and build-ups are not counted.
• Strength lifts: count completed sets with a step equal to the planned reps, or count single reps if the athlete is working to failure.
• Mobility and prehab: count rounds of the circuit rather than individual movements.

Once each exercise has a definition, it becomes a tag inside the athlete's counter. A tag has its own colored label, value, step and target, and you can add a short note describing the standard. Coaches who share an athlete benefit most from this, because the definition travels with the number.

How should you set up counters for a training block?

There are two common structures, and the right one depends on how you coach.

One counter per athlete. This suits individual sports and small groups. Name the counter after the athlete and the block, such as "Maya – hurdles block 2", and add a tag per exercise. Everything about that athlete's week sits in one place.

One counter per session. This suits a team coach who runs the same session for a whole squad. Name it after the date and focus, and add a tag per exercise or per group. Comparisons between sessions are easier, comparisons between athletes are harder.

Whichever you choose, use categories. They nest up to three levels, so a layout like "Senior squad > Sprints > Block 2" works without inventing a naming code. Categories can have their own colors and can be pinned, which brings this block's athletes to the top of the counter list. When a block ends, the counters stay where they are; you simply unpin the old category and pin the new one.

Counters can also carry a short code or initials, a color and a description. The code badge is handy when several athletes have similar names, because it is visible on the list card.

Step and target settings

The step is the amount added or removed per tap. It can be any value from 1 to 100, both per counter and per tag. A practical pattern:

• Single-contact plyometrics: step 1.
• Strength sets of five: step 5, so one tap logs the whole set.
• Rounds of a ten-movement circuit: step 1, counting rounds.

Targets let a tag count up or down to a goal. If the plan says forty ground contacts, set the target to forty and turn on a sound or vibration alert. If you prefer counting down, start from the planned volume and watch the number drop to zero. Two further options are worth knowing: auto-reset returns the tag to its start value when the target is reached, which suits repeated identical sets, and auto-lock freezes it so an accidental tap cannot add a rep that never happened.

Counting without breaking concentration

The counting screen offers three views of the tags: Single, List and Grid.

• Single shows one tag as a large circular counter with its target progress. It is the best choice when one athlete is doing one exercise and you want to see the number from a distance.
• List puts every exercise in a row with its own minus and plus buttons, value and target progress. It works for a circuit, where you jump between stations.
• Grid gives each tag a colored tile, useful when you are running several athletes in parallel and want large touch targets.

Tag display can be expanded, collapsed, or collapsed except the most recent. The last option is underrated: only the tag you touched last stays open, so the screen stays calm while you move through the session.

When nobody should touch the counter, lock it. A locked counter ignores taps, which matters when the phone is left on a bench and athletes pick it up to check their numbers.

Hands-free counting with the volume keys

Coaches spot, hold pads, feed balls and run stopwatches. Tapping a screen in the middle of that is awkward. During drills the volume buttons can do the counting, even in the background or on the lock screen, thanks to a foreground service. The keys can be remapped, and each key can have its own sound and vibration, so you know by feel whether you added or removed a rep.

This feature is off by default; switch it on in settings. Some devices may still show the system volume bar while you count, which is harmless. A lock-screen notification with minus, plus and Stop buttons gives another way to count without unlocking the phone.

Timed work and rest

Each tag can run its own timer or stopwatch. Timer presets are 30 seconds and 1, 2, 3, 5 or 10 minutes, or you can enter your own duration. A typical use is rest control between heavy sets: start a two-minute timer as the bar goes down, and the countdown beeps tell you when the next set is due. There are seven alarm sounds and eight vibration patterns, so choose one that you can hear over music in the weight room.

The stopwatch suits work intervals with no fixed length, such as "hold the plank as long as form is clean". Timers and stopwatches can be reset one at a time or all together from the List view.

How do taps become a weekly volume record?

Every tap is written to the history with its exact time, the step, the value before and after, and the tag label. That means the record of the week builds itself as you coach. Nothing needs to be copied out at the end of the day.

Notes can be attached to events. A quick note after a set, such as "dropped to 70 kg, back tight" or "stopped early, hamstring tension", keeps context beside the number. Notes are also collected on the All Notes screen, which can be sorted, so a week of observations can be read in one pass.

If an athlete records a video or you want a picture of a bar position, each tag can hold up to six photos. The photo editor lets you draw on an image, add text and rotate it, which is enough to mark a knee angle or a foot position.

Reading the dashboard

The dashboard gives an overview of a counter: the total and target, increments compared with decrements, an activity bar chart for the last seven days, and a pie chart by tag. For training volume, the bar chart is the most useful view. A week where one day towers over the rest is easy to spot, and that is often the day before a complaint of soreness.

The pie chart answers a different question: how the volume is split between exercises. If the plan said "mostly acceleration work" and the pie is dominated by bounding, the plan and the training have drifted apart.

How do you export reps to a coaching log?

When the week ends, export the counter. Counter App writes CSV, Excel (XLSX) and an HTML report with embedded photos. The export options let you include or exclude Summary, Events, Notes and Locations. For a volume log, Summary and Events are usually enough; add Notes when you want the comments in the same file.

In the spreadsheet, the event rows can be grouped by date to give daily totals, then by week. The app does not compute acute and chronic workload ratios, and it does not need to. Once the numbers are in a spreadsheet, you can apply whichever load model your program uses.
