Seam and Transom both protect your focus, but Seam times it and Transom gates it. Seam runs pomodoro-style focus timers, plus on-device dictation and a stack of notch tools, for $29. Transom decides who's allowed to interrupt a focus block, letting your chosen people, login codes, and real emergencies through while holding everything else, for the same $29. Buy Seam for timers; buy Transom for a filter.
- Seam schedules when you work; Transom decides who breaks the work.
- Both cost $29 once. Seam's free trial runs 48 hours and Transom's runs 7 days, no card for either.
- Only Transom reads your Messages, catches login codes, and shows a digest of what was held during focus.
- Pick Seam if you need timers; pick Transom if you can't trust the silence.
You start a Seam focus timer. Twenty-five minutes. The notch shows the countdown, clean and steady, and you get to work. This is the promise: structure your attention, run in blocks, build a rhythm you can trust.
Eleven minutes in, your kid's school texts "please call the office." The timer doesn't know. It keeps counting, calm as ever, while the one message that could end the session sits unseen behind it.
A timer told you when to focus. It didn't decide who was allowed to break it.
Seam is $29 and it's built well. Transom costs the same and takes the other half of the problem: not when you focus, but who gets through while you do.
Disclosure first, since it matters here. I make Transom. Seam is a real competitor and I've tried to describe it fairly, but you should know the author has a side.
Seam vs Transom: At a Glance
you protect your day with scheduled focus: pomodoro-style timers, on-device dictation, a light and dependable notch, a rhythm of timed work blocks you want to build a habit around.
you want to go quiet without going dark: choose the few people and alerts allowed to reach you, silence the rest, and get a digest of what was held.
Are Seam and Transom Even the Same Category?
They share a goal and split on method. Both want to protect your focus. One does it with a clock. One does it with a gate.
Seam manages the schedule of your attention. It structures when you work and counts down the block. Transom manages the gate to your attention. It decides who's allowed through the block while it's running. A timer is about time. A filter is about people. You can want both, but they're not the same purchase.
Who Seam Is Built For
The person who runs on timed focus and wants it dependable.
Seam is built around pomodoro-style sessions, and that emphasis is real. If the way you protect your day is to start a block, work until the timer ends, and take the break, Seam is a considered, reliable companion for exactly that habit. It also packs a lot around the timer: music, calendar, weather, on-device dictation and translation, even a live view of Claude Code's progress. For a timer-driven worker who wants a solid anchor at the top of the screen, it fits.
Who Transom Is Built For
The person whose problem isn't when, it's who.
You can already make yourself sit down for twenty-five minutes. What you can't do is trust the silence. The moment you go quiet, you start wondering what you're missing, so you check, and the focus is gone. Transom removes the wondering. During a focus block, your chosen people, your login codes, and a genuine emergency from anyone still reach you. Everything else is held and counted. When the block ends, one card tells you what waited.

The Real Pricing Math
Both are $29, once, so nobody's stuck on a subscription. The price is a tie. What it buys isn't.
Seam's $29 buys a timer and the extras around it: dictation, translation, weather, drop zones, at least a year of updates, on two Apple Silicon Macs. Transom's $29 buys the gate: who gets to break your focus, not when it starts, with free updates for good, on up to three Macs. Same money, different half of the problem.
Both let you try first: 48 hours for Seam, seven days for Transom, no card either way, and both refund within 14 days. An earlier version of this post said Seam had no free trial. It has one now.
Use Seam If
- Pomodoro-style focus timers are how you actually protect your day.
- You want a stable, dependable notch companion built around timed blocks.
- You want dictation and translation in the same app.
- You don't need your messages triaged by sender.
Use Transom If
- You can already sit down to focus, but you can't trust the silence.
- You want a chosen few and real emergencies through, everything else held, with a digest after.
- You want login codes to copy themselves in one tap.
- You want a full week on your own messages before you decide.
My Honest Take
Seam vs Transom is the difference between scheduling your attention and guarding it.
If you thrive on timed blocks and you want a dependable clock in your notch, Seam is a good buy, and I mean that plainly. But a clock can't tell your kid's school from a promo. Eleven minutes into that session, the office texted and the timer kept counting. Seam would have run the block beautifully. Transom is the one that would have let that one text through and held the other thirty. Decide which half of focus you're actually missing, and buy that one.

Seam vs Transom: FAQ
Is Transom a good Seam alternative?
If your goal is filtering interruptions rather than timing your focus, yes. Seam is the better pick for pomodoro-style sessions. Transom is the better pick if you want to choose exactly who can reach you and let everything else wait.
Does Seam have a free trial?
Yes. Seam offers a free 48-hour trial with no credit card, plus a 14-day money-back guarantee. Transom's free trial runs 7 days, also with no credit card, and it has the same 14-day guarantee.
How much do Seam and Transom cost?
Both are $29 one-time, and neither is a subscription. A Seam license covers two Apple Silicon Macs; a Transom license covers up to three, Intel included. Transom adds message triage a focus timer doesn't include.
What can Transom do during focus that Seam can't?
Transom lets a chosen few and a real emergency pierce the silence while holding everything else, then shows a digest of what was held. A pomodoro timer silences on a schedule but doesn't decide who's allowed through.
Does Seam read my texts to filter by sender?
No. Seam is built around focus timers and notch utilities. Transom is the one that reads your Messages on your Mac to pin cards from the people you choose.
Can I use a timer and Transom together?
Yes. Transom doesn't run pomodoro timers, so pairing a timer habit with Transom's triage is a reasonable setup.
