Mobile vision training you can do on your phone

Short answer: A phone can train the loop of see → decide → move. Keep sessions short, use the same device, and track averages rather than one lucky best score.

Vision training sounds like it needs special equipment, but a smartphone is enough for a useful daily routine. Browser games are especially practical because they show a visual cue, force a decision and record your response in one compact task.

What you can practice on a phone

• Rapid recognition — reading information that appears only briefly.
• Peripheral awareness — noticing changes away from the center of the screen.
• Visual search — finding the target among many similar items.
• Eye-hand coordination — tapping without wasted motion once you see the target.

How to keep the numbers fair

Use the same phone, brightness, posture and time of day when you compare results. Sleep, glare and touch latency can move scores more than people expect. Your average over several attempts is more useful than a single best run.

Recommended MIKIRI menu

• FLASH — instant number reading for rapid recognition and visual memory.
• MATCH — find the target number for visual search and decision speed.
• FOLLOW — track one dot through a shuffle.
• GATEFALL — read falling shapes and react in real time.

A 3-minute daily routine

1. Play FLASH twice and notice the speed where reading starts to break down.
2. Play MATCH once and focus on calm scanning instead of panic tapping.
3. Play FOLLOW or GATEFALL once for moving-target judgment.
4. Write down how it felt and compare your average, not only your best score.

Safety note

Phone-based vision training does not promise medical improvement in eyesight. If your eyes hurt, feel strained or vision changes, stop and consider professional advice. Short and repeatable beats long and exhausting.

MIKIRI play data

This part is not general knowledge. These are values actually recorded on MIKIRI's server (as of 2026-10-04; each completed run counts once, so repeat plays are included; flagged runs excluded). The samples are small — tens to a few hundred runs per mode — so read them as where real runs tend to land, not as settled statistics.

Full distributions for every mode are on the statistics page. These are in-game results, not medical or academic measurements.

What quietly changes your results on a phone

A phone is convenient but an unstable measuring instrument. If you keep a log, hold these constant:

• How you hold it. One-handed thumb play and index finger on a phone lying flat differ in travel distance and steadiness.
• Viewing distance. For brief-flash tasks, the apparent size of the digits changes the difficulty itself.
• Low-power mode. Some phones drop the refresh rate to save battery, which changes when things appear on screen.
• Notifications. If one arrives mid-run, discard that attempt.
• Brightness and room light. A bright screen in a dark room changes afterimages and glare.

MIKIRI keeps your personal bests on the device (in local storage), but it cannot record these conditions. When one of them changes, treat your history as starting again.

Phone vs. computer: why the results don't line up

The same person playing the same mode will get different results on a phone and a computer. That is not ability — the controls are built differently:

• Input distance. On a phone your finger travels across the glass; on a computer you move a mouse and then click. Modes with movement (NEXT, the aim test) feel this directly.
• Screen size and distance. In FLASH, how much of your field of view the digits cover changes how hard the level is.
• Stability. A hand-held phone moves slightly, which matters for tracking modes.
• Touch precision. Taps land less precisely than clicks; on crowded boards that means more mis-taps.

Which one is easier depends on the mode, so the safe rule is simply: don't compare across devices.

A log with only three fields

You don't need an app to keep a useful record. Three things per session are enough:

1. Date and time of day (morning, afternoon or evening).
2. Mode and result — the median of five runs, not the average and not the best.
3. The one thing you focused on ("kept my eyes on the centre", "read the gap first").

The third field is the one that pays off later. A column of scores tells you that something changed; the note tells you what you were doing when it did.

FAQ

Can phone games really help?

They can train task-specific habits such as where to look, how to decide and how to move. They do not guarantee medical eyesight improvement.

How long should I train each day?

Start with 3 to 5 minutes. Short sessions under similar conditions make progress easier to compare.

Which game should I try first?

Start with FLASH and MATCH, then add FOLLOW or GATEFALL for moving targets.
