Multi-task Pomodoro & Flowtime

Switch between your activities. Stay in flow longer.

Most focus timers force the same loop: work, then sit through a break. Sunny is different. You alternate between the activities you chose. Pair deep work with email. Writing with reading. A hard task with an easy one. Switching is the break.

Sunny's focus screen: a Focus ↔ Break session counting down 24:46 on the sunrise dial, with the mascot above it and a hold-to-switch button.

The method

Not work → break. Activity ↔ activity.

Multi-activity interval switching treats the switch itself as the reset. Discipline-heavy work feels lighter, almost like a game, and you stay engaged far longer.

Pick your activities

Two is the sweet spot: pair a hard task with an easy one. Deep work with email, a report with reading, or two goal activities on a strong day.

Give each side its own rule

Timed with a gentle chime (25/5, 10/3, 7 minutes, whatever fits) or “until done” with no countdown at all. Asymmetric on purpose.

Switch, don’t stop

When the chime comes, Sunny asks and you decide. Switching is the break, so you keep momentum instead of losing it to an idle break.

Read the full method

Flexible where it matters

A timer that adapts to you, not the other way around

Clean and minimal by default, with the power options one tap deeper, never in your face.

Timed or until-done

Countdown intervals with a gentle chime, or open-ended Flowtime-style segments you end when the task is actually finished.

Different rules per side

Twenty-five minutes of deep work against seven of email. A timed side and an until-done side. Your intervals, not a template's.

The timer asks. You decide.

When the chime rings, switch, or add 1 or 5 minutes. With three or more activities, you pick what comes next. Prefer hands-off? Turn on Auto-switch in Settings.

Done early? Hold to switch

Finished before the chime? Hold the button and switch whenever you like. No quiz before your first timer: open, tap, focus.

Starter sets

Just focus · Pomodoro 25/5 · Short cycles 10/3 · Work ↔ Fun. Your first session is running in under a minute, with no setup.

Also just a great timer

Skip the method entirely: one activity, simple rounds, a clean dial. Sunny stays out of your way while you work.

Built to be trusted

Lock the phone. Pocket it. The timer holds.

The number one complaint about focus timers is that they quietly die in the background. Sunny treats background reliability as the headline feature, not a footnote.

Exact alarms, even asleep: Interval ends are scheduled with the OS ahead of time, so the chime rings on the second: with the screen off, the app suspended, even after a reboot.
Survives force-quit: Every change is saved at once. If the system closes the app mid-session, reopen Sunny and tap Resume: you pick up where you left off, with the time that passed counted.
Timestamps, not tick counters: Elapsed time is derived from wall-clock timestamps, never accumulated. Backgrounding, throttling or clock quirks can’t drift the timer.
On your Lock Screen: On iPhone, a Live Activity on the Lock Screen and in the Dynamic Island lets you pause, resume and switch. On Android, a live notification does the same. Widgets on the Home Screen and Lock Screen start your set in one tap.

Questions

The short version

What is Sunny?

Sunny (Sunny: Focus & Study Timer) is a focus timer for iPhone and Android. Instead of alternating work and rest like a Pomodoro timer, you alternate two or more activities you chose, each with its own rule: a countdown such as 25 or 10 minutes, or until done. Switching is the break. It works offline, needs no account, shows no ads, and the full timer is free forever.

What is multi-activity interval switching?

Multi-activity interval switching is a focus method where you cycle between chosen activities at intervals. For example: deep work for 25 minutes, then email for 10, then back. The switch itself acts as a mental reset, so the “break” can be a second productive activity. Read the full write-up on the method page.

How is Sunny different from a Pomodoro app?

Pomodoro apps model work followed by an idle break, with one fixed rhythm. In Sunny, both sides of the loop are real activities you chose, and each side can have its own rule: 25 minutes here, until done there, 7 minutes somewhere else. When the chime rings you switch, or add 1 or 5 minutes. If you want plain Pomodoro, Sunny does that too: the Pomodoro starter set is one tap, and Short cycles 10/3 is a shorter, ADHD-friendly rhythm.

Does Sunny support Flowtime?

Yes. Sunny's 'until done' rule is Flowtime applied to alternation: no countdown, no counting. Work until you finish what you intended, then tap Switch. You can mix rules freely, for example a timed activity on one side and an until-done activity on the other.

Does the timer keep working when I lock my phone or quit the app?

Yes. This is Sunny's core engineering promise. Time is anchored to wall-clock timestamps, never a running counter, so backgrounding or locking the phone cannot drift the clock. Interval ends ring through exact scheduled alarms even when the app is suspended or killed. On iPhone, a Live Activity on the Lock Screen and in the Dynamic Island shows the countdown and lets you pause, resume and switch; on Android, a live notification does the same. If the system closes the app mid-session, reopen Sunny and tap Resume: the session picks up where it left off, with the time that passed counted.
