About 15Minutes
What Is 15 Minutes
15 Minutes is a time-awareness app from the developer Devpool, sold on the App Store as 15 Minutes - Timer Tracker. Instead of running a stopwatch in the background, this time tracking app splits your day into 15-minute slots and asks you to write a few words about what you just finished. Over a day you end up with a plain record of your time, built one short note at a time.
The idea behind the app is that most people misjudge how they spend their hours. A tracker that measures everything automatically can feel heavy, and a to-do list only shows what you planned. 15 Minutes aims at the middle. The interval is short enough to catch when you switch tasks, and long enough that it doesn't nag. The developer calls this balance the core reason for the quarter-hour design.
You should know what it isn't before you download it. It won't log anything by itself, so if you ignore the reminders you get no data. It's also an iOS-only release that runs on iPhone, iPad and Apple Vision Pro, with no Android or web version. And it's a paid app rather than a free one with upsells. Both limits are worth weighing against how much you actually want to track.

Key features
Quarter-Hour Slot Logging
The whole app is built around one behavior: noting what you did every 15 minutes. A notification arrives at each interval and you reply with a few words, either inside the app or straight from the notification. The app calls this method a way to become aware of how you actually spend your time, and the short log is what every other feature reads from. You can adjust the slot length if a fixed 15 minutes doesn't fit your schedule.
Focus Mode
Focus Mode turns the app into a light sprint timer. You start a session, a countdown ring shows the time left in the current slot, and the screen stays awake so the timer stays visible. When the 15 minutes run out, the app asks what you did and starts the next session on its own. The loop is simple by design: focus, log it, go again. It's a gentler take on the Pomodoro idea, aimed at logging rather than strict break scheduling.
Daily Goals
Each morning you set three goals for the day. They stay pinned at the bottom of the screen so they remain in view while you work, and you can look back at yesterday before you commit to today's. The goals sit next to your logged slots, which makes the link between intention and what you actually did easy to spot. Three is the fixed number, so the feature nudges you to pick the few things that matter.
Stats and Insights
The stats view turns your notes into pictures. You get a day summary with a time breakdown chart, plus a completion rate, your unique tasks and total time tracked. It also tracks current and longest streaks, activity by hour and by weekday, and your most frequent tasks across the week, month or all time. Together these views work as a simple productivity tracker, and the streak counter is the piece that keeps the daily habit going.
Quick Add and Day Off
Two features handle the days that don't fit the loop. Quick Add lets you fill in a whole day of slots in seconds, which is useful when you track after the fact instead of in the moment. Day Off pauses the reminders for a rest day so a quiet Sunday doesn't sit in your history as a failure. Both keep the log honest without forcing you to fake entries just to protect a streak.
Export and Sync
Your data syncs through iCloud, so the same log follows you across iPhone, iPad and Apple Vision Pro. From Settings you can export your history as a CSV for a spreadsheet, a JSON file for a full backup, or a PDF report covering the current week, the current month or everything. The exports make the app usable for records you might want to keep outside the phone, and the developer notes support for English, French and Spanish only.
Pros and cons
Pros
- The quarter-hour reminder is short enough to fit a normal day yet frequent enough to catch task switches
- Replying to the notification means you log an activity without opening the app, which lowers the friction that kills most trackers
- Focus Mode, daily goals and stats live in one app, so you don't need a separate timer and a separate journal
- A one-time $3.99 price means no subscription, and iCloud sync keeps your history across your devices
- Quick Add and Day Off cover the days you forget or rest, so the log stays realistic
Cons
- It never tracks on its own, so every entry depends on you noticing the reminder and replying
- There's no Android or web version, which rules it out for anyone who doesn't own an Apple device
- A paid upfront app with no free tier means you can't try the workflow before you buy
- The interface and reminders ship in English, French and Spanish only, so other languages get partial coverage
