SumvoroWe log changes that affect calculations, assumptions, usability, accessibility, sourcing, or the way people make decisions with Sumvoro.
Expanded fifteen calculator explanations with specific examples and limitations, restored search eligibility for ten complete tools, removed a repeated advice panel, clarified Sumvoro’s maintainer identity, and separated vehicle value loss from cash spending. Search eligibility does not guarantee Google indexing or ranking.
Added a monthly income worksheet for salary, hourly pay, commissions, self-employment, gig work, seasonal earnings, multiple sources, USPS statements and Army/military LES entitlements. Manual YTD pay-stub entry separates base and variable earnings, with short-history warnings and explicit coverage dates. Eight companion planners cover irregular income, gig earnings, income goals, marginal commission tiers, tips, freelance capacity and income interruption. No paid API, upload or customer account is required.
The shared result card now has consistent alignment, readable statement outcomes and a compact action footer. Calculator depth uses a sliding selection indicator and a smooth in-place reveal, without introducing a sidebar or resizing the workspace. Car-affordability results show the loan-payment budget and ownership allowance; cash reserve sections have relevant labels. Existing inputs, saved scenarios, reporting and reduced-motion support are preserved.
Ten fictional worked models now load directly into their calculators. Four existing, sourced calculators join the curated search publication set. Car-buying and land-financing resource packages, a reproducible loan-term graphic, private growth experiments and consented referral categories are added. External outreach remains draft-only; no paid advertising, customer accounts or traffic purchases are enabled.
Added universal calculator undo and redo with a bounded 40-step local history, familiar keyboard shortcuts, and a persistent adjustable results-panel width. Upgraded Math Lab function graphing with zoom, pan, reset, live coordinate inspection, and clearer assistive-technology guidance. Accounts and monetization remain inactive.
Rebuilt every calculator category as an intent-based authority hub with guided decision paths, responsible-use principles, stronger internal linking, and a clearly separated complete library. Added a 25-calculator priority certification set to the admin quality center and automated checks that prevent missing calculators, broken topic paths, or incomplete hub coverage from shipping.
Unified the sixteen-platform roadmap around a denser calculator cockpit. Every calculator now includes persistent compact and comfortable density settings, a distraction-free focus view, and keyboard switching between Results, Insights, and Save & report. Existing decision intelligence, guided workflows, reporting, Math Lab, search, trust, accessibility, growth, operational, and dormant monetization systems remain connected rather than duplicated.
Introduced a public status registry for all 172 calculators, calculator-level verification panels, visible scope classifications, a stricter automated release gate, an admin source-review queue, portable local workspace backups, offline resilience for visited tools, and a dramatically smaller homepage ribbon asset. Accounts and monetization remain optional and inactive.
Added a Search Console opportunity queue, privacy-safe search-to-calculator completion measurement, contextual next-step tracking, five new high-intent guides, improved calculator metadata, compact share summaries, and a weekly quality-and-release workflow. Monetization remains disabled.
Introduced consistent Simple, Advanced, and Professional calculator depths plus a universal Decision Explorer. Users can now test important assumptions by 10% and watch results update immediately, then save, compare, share, export, or print the scenario without an account.
Added guided linear and quadratic equation solvers, a live polynomial function graph, exact polynomial derivative and definite-integral tools, and a two-equation system solver. Each tool teaches the method and states its mathematical scope.
Added Fixed vs. ARM Mortgage, Salary vs. Hourly Pay, and Freelance Rate calculators, plus a faster searchable and sortable calculator directory designed for a growing professional library.
Introduced a dedicated site-wide search experience with keyboard navigation, contained scrolling, clearer result types, and direct access to the complete calculator directory.
Added visible methodology sources, reviewed dates, editorial standards, a corrections policy, an About page, and structured author and reviewer information.
Expanded calculators with advanced assumptions, expandable optional sections, custom terms, printable reports, saved scenarios, and side-by-side decision support.
