Bounded Self logs a single energy cost per activity and rolls it into a weekly envelope budget for your whole life. EMRALD sets an effort level before the work, rates the real effort after it, and calibrates the two against each other inside the system where your projects live. Both found the same gap. They bet on different fixes.
If you're comparing these two, you've probably already tried logging how work feels and want to know which model actually holds up over time.
Bounded Self asks you to rate the energy cost of each activity on a 1-10 scale, tag it with a category, and let the app build a rolling picture of your day. Entries take about ten seconds. The scale is personal: the product's own FAQ says everyone's number is their own, with no anchor to calibrate it against. Logging happens after the fact, seven to ten entries a time, two to three times a day, by hand. There's no prospective estimate and no duration attached to any entry, so it can't answer what an hour of something costs. It only knows what the whole activity cost, once it's over.
Its flagship feature is well designed: cost-shift detection. When something that usually costs a 3 suddenly costs an 8, Bounded Self flags the deviation against your own rolling baseline, no machine learning involved, just a threshold on your own history. Premium adds envelope-style budgeting on top: a weekly pool, per-category allocations, carryover between weeks, transfers, and a "set from averages" option that reads your past eight weeks. It also adds an experiments feature: hypothesis, measured direction, a baseline window, a minimum data point count, and a verdict based on statistical significance. That's a genuinely thoughtful design for someone who wants to test a change in their life and see if the numbers back it up.
The scope is life-wide by design. Categories include family and social time, and people tags cover things like "Mom" or "Romantic Relationship." The product's own copy says it isn't a wellness app, it's an energy management tool for knowledge workers, though the data model (mood-adjacent tags, people, locations) reads close to wellness tracking regardless of the label. There are no integrations: every data point is typed in by hand into a standalone web app. Data exports as documented JSON at any time, and the builder states plainly that nothing gets sold, everything is encrypted, and you can delete your data within 30 days of asking. Analytics cookies are on by default and can be turned off.
Pricing is free for unlimited entries, ten default categories, mood and people and location tags, and a dashboard with 7-day charts. Premium is stated as $6/mo on the pricing page and $10/mo in the docs, and it unlocks envelope budgeting, custom categories, a journal, longer history windows (30-day, 6-month, 1-year), and the experiments feature. Worth noting for anyone comparison-shopping: the product's sitemap shows its last content update was April 30, 2026, more than five months without a new page or documentation change as of this writing.
EMRALD sets an effort level before the work, rates the real effort after it, and lets the two calibrate against each other, inside the system where your projects live. That's the whole mechanic. You pick one of four built-in effort levels (E1 through E4) when you start a session, work, and stop it. Stopping triggers a five-question effort receipt covering six effort sources (complexity, emotional drain, motivation cost, novelty, physical demand, uncertainty) plus flow and any complications, roughly ten to fifteen seconds. Because the session is timed, EMRALD knows duration, so it can calculate cost per hour and, with the Toggl integration, per billable hour, a question an untimed entry can't answer.
The receipts feed a personally calibrated cost model. A drift check (D19) flags when your ratings stop lining up with your own patterns, so a "7" this month doesn't quietly mean something different from a "7" last month without anyone noticing. Twenty metrics sit across four categories: Effort, Calibration, Productivity, and Energy. The free tier includes the first eight, plus burnout warnings, and never locks reads or history behind a paywall. The Burnout Monitor itself runs free on every plan, computed from checkable math, watching sustained-effort patterns rather than waiting for symptoms to show up downstream. Pro, at $5 a month or $42 a year, opens the remaining twelve metrics, custom effort levels, and the full insight engine, with daily and monthly digests added to the free tier's weekly one.
EMRALD is project-scoped, not life-wide. It lives inside the tools where your projects already sit: an MIT-licensed, open source Obsidian plugin, and a Toggl browser extension that launched September 2026, in addition to a separate web app. It only ever sees session data, never the content of your notes or work. There's no built-in experiment framework the way Bounded Self's Premium has one. What it has instead is the closed loop: a plan before the work, a rating after it, and calibration that tracks whether the two are drifting apart. The research behind that model is documented at getemrald.com/learn.
A question list, because Bounded Self and EMRALD answer different questions about the same underlying concern: what your day or your work is costing you.
| Question | Bounded Self | EMRALD |
|---|---|---|
| How do you log the cost? | Rate 1-10 per activity, by hand, after it happens | Set an effort level before the work, rate it after |
| Is there a prospective estimate? | — | Yes, E1-E4 set before the session starts |
| Does it compare a project's expected cost to what it actually cost? | Week level only: an energy budget against logged spend, no per-project plan | Yes. Projects carry an expected effort level from creation; receipts record the actual; calibration tracks the gap |
| Does it know duration or cost per hour? | — | Yes, session-timed, per hour; per billable hour with the Toggl integration |
| Does it calibrate your ratings over time? | No, the scale is personal and unanchored per its own FAQ | Yes, drift detection flags an off-baseline answer |
| Does it catch sudden cost shifts? | Yes, flagship feature: rolling baseline vs. current cost | Trends and Discovery insights surface shifts, no dedicated drift card |
| Does it budget by week? | Yes, envelope budgets with carryover (Premium) | Daily percent per project, no weekly ledger |
| Does it run experiments on your own data? | Yes, hypothesis and verdict framework (Premium) | — |
| Does it detect burnout risk? | Cost-shift alerts framed around burnout in its marketing | Burnout Monitor, free on every plan, checkable math |
| Does it connect to the tools you work in? | — | Obsidian plugin (MIT) and a Toggl browser extension |
| What's the scope? | Life-wide: work, family, social, errands | Project-scoped: any project you run as sessions, work or personal |
Bounded Self covers more of your life in one number. EMRALD covers less ground but ties the number to a plan, a duration, and a calibration check. Neither row is a knockout. They're built around different bets.
If you want one number that covers your whole life, not just work: family time, social plans, errands, alongside your job. The envelope-budget metaphor makes energy feel spendable across all of it, and the cost-shift alerts are a genuinely useful early warning inside that life-wide frame. You don't need a prospective estimate or an hourly cost figure to get value from it.
If your energy questions are about project work specifically, and you want the estimate-then-rate loop tied to actual project sessions inside the tools you already use. You get a per-hour cost figure, drift detection on your own ratings, and a free Burnout Monitor with no paywall, at the cost of not covering the parts of your life that aren't projects.
If you want the full picture: personal energy patterns across your whole life from Bounded Self, and calibrated, session-level effort cost for the projects you run from EMRALD. They share the receipt idea but don't share data or scope, so cross-referencing them weekly is a manual habit, not an automatic sync. Still worth doing if a rising cost in one shows up as drift in the other.
Bounded Self and EMRALD found the same gap independently: time management alone doesn't account for what work costs you. They reached for the same metaphor, a receipt, a budget. Then they made different bets.
Bounded Self bet on simplicity and range. One number, logged by hand, covering everything from a client call to a family dinner, rolled into an envelope budget you allocate before the week starts. That bet pays off in breadth: it's the tool for someone who wants a single energy figure for their whole life. The cost it pays is precision. A 1-10 slider with no duration and no anchor drifts with your mood, and there's no way to plan an estimate before the activity starts, only to log it after.
EMRALD bet on the closed loop instead: set an effort level before the work, rate the real effort after it, and let the two calibrate against each other, inside the system where your projects live. That bet pays off in precision for the part of life it covers. The cost it pays is range. It has nothing to say about a family dinner or a social plan, because it was built to sit inside the tools where your projects already are, not to replace your whole day.
Both products deserve credit where they've earned it. Bounded Self's cost-shift detection and envelope budgeting are well built, and the builder keeps the pitch honest about being an energy tool rather than a wellness app. It's also fair to note, factually, that the product's own sitemap shows no content update since April 30, 2026. Readers comparison-shopping should know that.

Tell usThe two products don't sync. Running both means keeping the comparison manual, but the comparison itself is where the value shows up:
One week won't show much. A month of both records side by side starts to show whether a rough week at work is showing up in your life-wide budget too, or whether the two are tracking separate things entirely.
Bounded Self logs a single 1-10 energy cost per activity, by hand, and rolls it up into weekly envelope budgets across your whole life. EMRALD sets an effort level before work, rates it across six effort sources after each session, and calibrates planned against actual over time, inside the project system you already use. One covers more ground; the other ties the number to a plan, a duration, and a calibration check.
No native desktop app; it's a web app that installs as a PWA (pin it to a taskbar or add it to a home screen). EMRALD's web app installs the same way, and adds an Obsidian plugin and a Toggl browser extension. Neither product is listed in the iOS App Store or Google Play; on a phone, both install from the browser.
Yes, with a caveat. They cover different scope: Bounded Self is life-wide, EMRALD is project-scoped, covering any project you run as sessions, professional or personal. They share the receipt idea but don't share data or sync automatically, so combining them means comparing two separate records by hand, typically at the end of the week.
Both approach burnout upstream, before it becomes a crisis, rather than by tracking symptoms after the fact. Bounded Self's mechanism is cost-shift detection: when something that used to cost a 3 starts costing a 7 or 8, it flags the deviation against your own rolling history. EMRALD's mechanism is the Burnout Monitor, computed from twenty derived metrics with checkable math and free on every plan. They come at the same problem from different data depths, one number per activity versus a calibrated multi-factor model.
Bounded Self is free for unlimited entries with charts capped at a 7-day window. Premium is stated as $6/mo on the pricing page and $10/mo in the docs, and unlocks envelope budgeting and longer history windows. EMRALD is free for 8 of 20 metrics and never locks reads or history behind a paywall at any tier; Pro is $5/mo or $42/yr. The free-tier cap on chart history is specific to Bounded Self; EMRALD's free tier doesn't carry that limit.
