Sunsama plans your day. EMRALD tells you what it cost you. They're different instruments, and you can use both. Sunsama is a daily planner that offers timeboxing, guided rituals, and a shutdown routine that stops overcommitment before it starts. EMRALD is a measurement layer that tracks effort cost, calibrated to you personally, on top of whatever planner you already run.
If you came here typing "Sunsama vs EMRALD," you're probably already using Sunsama and sensing a gap. This comparison offers an explanation of what, and why, that gap exists.
Sunsama calls itself a daily planner that pulls tasks from your other tools into one focused workspace. That's accurate, and it's good at it. It syncs calendars, timeboxes your day, auto-schedules where it can, and runs guided morning and evening rituals that plan the day, close the day, and showcase the highlights. It has a focus mode with pomodoro timers, meeting scheduling links, and integrations with more than ten task apps.
The independent reviews back this up. The NYT's Wirecutter named Sunsama the best scheduling tool in its roundup of AI scheduling apps. A therapist writing for SaskADHD reviewed it specifically for ADHD executive dysfunction stating the guided rituals, the time-estimation feedback loop, and the workload guardrails address real gaps that generic to-do apps miss. If you struggle to know what to do next, or you habitually overload your calendar, Sunsama earns its subscription.
Pricing: At the time of this comparison, Sunsama's Pro plan runs $17/mo billed yearly or $22/mo billed monthly, with unlimited integrations and a 14-day trial and no free tier. Team plans run $20-25/mo per person. One plan, one price point, no feature gating: you get everything or you don't sign up.
Sunsama also has a feature called Analytics, which is worth clarifying up front. It shows daily and weekly summaries of time spent by task, planned hours against actual hours. That's a real feature, but it isn't an effort metric. It tells you how long something took. That's not the same as telling you what that something took out of you.
EMRALD isn't a planner and doesn't attempt to compete for that job. It's a measurement layer: create a project with its expected effort level, start a session when you begin the work, complete a 5 question feedback receipt after the session ends, and EMRALD builds a personally calibrated cost model from that input over time. The model offers twenty metrics across four categories: Effort, Calibration, Productivity, and Energy. A Burnout Monitor watches sustained-effort patterns and surfaces risk signals before they become a bad month, and that monitor is never paywalled. It ships free.
It started as an Obsidian plugin and lives there today, alongside a standalone web app at app.effortmastery.com. It works from session data only and can't see any note or work content. The Obsidian plugin is MIT-licensed and open source, so you can read the code that runs in your vault. Free tier covers core tracking, eight of the twenty metrics, and burnout warnings. Pro is $5/mo or $42/yr and unlocks the full metric set, AI insights, custom effort scale levels, and expanded digests.
The design premise is stated plainly on getemrald.com: it's the only tool treating self-reported effort as the input to a continuous, calibrated cost model rather than a timer with a label on it. A model that learns what your effort actually looks like, personally, and flags when it's drifting somewhere bad.
This question list highlights topics knowledge workers are thinking about more and more, especially with the increasing integration of AI into workspaces. See what tool provides answers below:
| Question | Sunsama | EMRALD |
|---|---|---|
| What should I do today? | Daily planning ritual | — |
| How long did it take? | Planned vs. actual timer | — |
| What did it cost me in effort? | — | Calibrated effort rating |
| Am I heading toward burnout? | Workload guardrails only | Burnout Monitor |
| How is my recovery trending? | — | Recovery metrics |
| What's my flow quality? | Focus mode (surface-level) | Flow frequency & quality score |
| What does it sit inside? | Cross-platform app (web, desktop, mobile) | Obsidian plugin + web app (roadmap: more integrations) |
Read the table straight down and the pattern is obvious: Sunsama owns the top of the day regarding what to do and how long it takes. EMRALD owns the aftermath, analyzing what the day took out of you, and whether that cost is sustainable. Neither row is a knockout. They're just not the same question.
If your problem is upstream of effort: you don't know what to work on, your calendar is a mess of double-bookings, or you routinely commit to more than a day can hold. Sunsama's rituals and guardrails are built for exactly that. If task chaos is your bottleneck, a cost model won't fix it because you need the planning layer first.
If planning isn't your problem. Your calendar might already be tight, your days might already be timeboxed, and you still end most weeks depleted in a way you can't explain from the schedule alone. That's a measurement gap, not a planning gap. EMRALD exists for the moment you finish a "perfect" day, one where all boxes were checked and every timeblock honored, and still feel wrecked with no record of why.
If you already run a planner (Sunsama or otherwise) and want to know what running it is costing you. This is the honest middle case, and for most people who've gotten this far into a comparison page, it's the right one. Plan in Sunsama. Measure in EMRALD. Compare the two records at the end of the week and you'll see something neither tool shows alone: the days that looked identical on the calendar but weren't identical in the body.
Sunsama helps you plan. EMRALD helps you pace.
That's the actual shape of the problem, not a hedge to avoid picking a side. A planner and a cost meter aren't competing for the same job, any more than a calendar competes with a fuel gauge. You need the calendar to know where you're going. You need the gauge to know if you're going to make it there on what's in the tank.
Sunsama's own comparison page makes the same argument about its other competitors. It tells you why it isn't here to replace Akiflow, Motion, Reclaim, ClickUp, or Todoist, and pitches using them together. We're borrowing that same honesty here, because it happens to be true in this case too: Sunsama plans, EMRALD measures, and there's no reason to make either tool pretend to do the other's job.
It's worth naming plainly, since it's the quiet part of this whole comparison: Sunsama is a subscription product and its business depends on you opening it every day. It can build workload guardrails with soft warnings that you've overplanned, but it can't ship "today costs too much, do less" as a headline feature, because that's the opposite of an engagement metric. EMRALD doesn't have that problem. A day where EMRALD's honest answer is "rest" isn't a failure of the product. It's the product working.

Tell usIf you're running both, here's the loop that makes it worth the extra ten seconds a day:
The value of both shows up at step 4 and 5, not before. One week of data is a curiosity. Four weeks is a pattern. The day type that always costs more than the calendar suggests, the task you keep underestimating, the week you should have taken lighter all rise from the data to show themselves with a lot more clarity.
No. Sunsama tracks planned time against actual time. EMRALD is built specifically to answer what tasks cost you in effort, using a calibrated model rather than duration alone.
Sunsama's analytics feature shows daily and weekly summaries of time spent by task, which is how your planned hours compare to your actual hours. It doesn't measure effort intensity, cognitive load, or burnout velocity. It's a time report, not a cost report.
Sunsama plans your day through tasks, timeblocks, and rituals. EMRALD tracks what each session actually cost you in effort. Two layers, complementary. Use Sunsama to decide what to do; use EMRALD to know what it took. Using both? Let us know if you'd want a direct Sunsama connector. It helps us prioritize what to build next.
Sunsama has workload guardrails that appear through planned-hours warnings, and a shutdown ritual meant to prevent overwork. It doesn't have a burnout risk monitor. EMRALD's Burnout Monitor watches sustained-effort patterns: accumulation, recovery quality, and velocity toward exhaustion, and it's free on every plan.
No. They measure different things. Sunsama is a planning layer that helps you decide what to do and when. EMRALD is a measurement layer that tells you what doing those things cost you. Most people who need one eventually find they'd benefit from both.
Time tracking, which is what Sunsama's timer does, measures the duration of your work. Effort tracking, which is what EMRALD does, measures the cost (in terms of exertion), or how hard that duration was compared to your mental or physical limits, calibrated to you personally over time. Two tasks can take the exact same forty-five minutes and leave you in completely different states. Only one of those tasks shows up differently in a time log.
Honestly, if you struggle with overcommitment, want structured morning and evening rituals, or need one workspace pulling tasks from several tools, then yes, for that job it's a strong product with real reviews behind it. But it only measures time. If the question you actually need answered is what your work is costing you, Sunsama alone can't answer it. That's a different instrument.
