Score your product against five named UX laws.
A free 40-question UX audit tool — every question tied to a specific named principle. Hick's, Fitts', Doherty, Jakob's, and Nielsen's heuristics. Get a score, a prioritized fix list, and a shareable report URL. No signup, no email, no upsell wall.
Built by Masfa Zulfiqar — a UI/UX designer running a small named-pattern audit practice in Karachi. The rubric is the same methodology used on every paid audit engagement, condensed into something you can self-run in 15 minutes.
Four steps, fifteen minutes.
- 01
Pick your product type
SaaS, e-commerce, fintech, crypto, AI product, or something else. The rubric weights questions differently for each — mobile tap targets matter more on e-commerce than B2B SaaS, error prevention weighs heaviest on fintech.
- 02
Answer 40 questions across 5 sections
Eight questions per named law. Each on a 1–4 severity scale (1 = no issue, 4 = severe violation). Each comes with a "why this matters" note and a real-product example so you can answer honestly. Takes 10–15 minutes if you have the product open.
- 03
Get your score + prioritized fix list
Overall 0–100 score, A+ to F grade, per-law breakdown, top-5 fixes ranked by impact. Each fix names the law, explains why it matters for your product type, and links to a case study showing how I solved the same pattern in production.
- 04
Share the result URL or download the report
The result page is a permanent, shareable URL — paste it in Slack, post it on LinkedIn, send it to your team. If you want professional eyes on the same gaps, the paid audit service is one click away.
Five sections, eight questions each.
Each section anchors on a different named pattern that diagnoses a specific failure mode. Together they cover the gaps that account for roughly 80% of the friction I see in audit engagements.

Hick's Law
Decision time grows with the number of options.
Every screen asks the user to make decisions. The more decisions visible at once, the slower the commit and the higher the chance of abandonment. Hick's Law isn't an argument for fewer choices in absolute terms — it's an argument against unstructured simultaneity.

Fitts' Law
Tap target size + distance = mis-tap rate.
The time to hit a target scales inversely with its size and proportionally with its distance from where the user's pointer (or thumb) starts. Small distant targets cost time and accuracy. Large nearby targets convert faster. The most expensive Fitts' violations sit on destructive actions placed where users tap most.

Doherty Threshold
Productivity collapses past 400ms of latency.
When the system responds slower than ~400ms, the user's attention drifts and productivity drops sharply. Originally framed for compute latency, the threshold generalises to any case where decision-critical information sits one interaction away from where the user expects it.

Jakob's Law
Users spend most of their time on other products.
The user comes to your product with a mental model trained by the dozens of other products they use. Reinventing patterns for the sake of brand identity makes them work harder; matching established conventions lets their existing muscle memory carry them through. Innovate where it matters; conform where it doesn't.

Nielsen's Heuristics
Ten heuristics from 1994 that still hold.
Jakob Nielsen's 10 usability heuristics, condensed to eight working questions. These are the deepest, most general principles in the rubric — every product can be evaluated against them, and the ones that score best across all eight are the ones users return to.

Same conversation, better artifact.

|---|---|---|
| Each finding tied to a named UX law | No | Yes — every question |
| Weighted by product type | No | Yes — SaaS / fintech / ecommerce / crypto / AI |
| Prioritized fix list (top 5 by impact) | Maybe | Yes — ranked by severity × weight |
| Shareable artifact / report URL | No | Yes — persistent, encoded, no signup |
| Resume mid-session | No (chat resets) | Yes — localStorage |
| Case-study references for each gap | No | Yes — Take Therapy, Painted Juttay, Enrichplay |
| Cost | $20/mo | Free |
Audit yourself, then fix the rest.
The self-audit gets you 80% of the way. The remaining 20% — the gaps that need an expert eye, the trade-offs that need a defensible argument — is where the paid audit picks up.
Frequently asked.
Genuinely free. No signup, no email required, no upsell wall between you and the score. The tool runs entirely in your browser — answers never touch a server. You get the full 40-question audit, the prioritized fix list, the case-study callouts, and a shareable result URL. The only paid option is a 90-minute pro audit ($450) if you want me to do this for you with my own eyes on your product.
ChatGPT gives you generic UX advice. This rubric ties every question to a specific named UX law (Hick's, Fitts', Doherty, Jakob's, Nielsen's heuristics) and weights each gap by its impact on your product type (SaaS scores Hick's violations heavier than e-commerce, ecommerce scores Fitts' tap-target gaps heavier than SaaS). The prioritized fix list is the artifact you actually share with your team — score, breakdown, fixes ranked by impact. ChatGPT doesn't produce that.
1 = pattern is correctly applied, no issue. 2 = minor gap, small tweak would help. 3 = meaningful friction, costs the user real time or trust. 4 = severe violation, actively losing users or causing errors. Honest 3s and 4s are more useful than aspirational 1s — the report only surfaces real fixes when the data reflects real gaps.
Yes — your answers persist in your browser's localStorage as you go, so you can close the tab and come back. The result URL is also stateless: once generated, you can bookmark it, share it, or come back to it any time.
Depth beats breadth. Each of these five laws diagnoses a different failure mode (decision density, tap-target accuracy, latency, convention-breaking, error prevention). Together they cover roughly 80% of the UX gaps I've found in 4 years of audit work. The other 20% needs an expert eye, not a checklist — that's where my paid audit service picks up.
Yes. Pick "SaaS / Dashboard" as your product type and the rubric weights internal-tool patterns appropriately (Hick's violations are weighted heavier; Fitts' mobile-specific questions are weighted lighter). The result is calibrated for the surface you're auditing.
Once your report is generated, the result URL is permanent and shareable. You can paste it in Slack, post it on Twitter/LinkedIn, or link it from a "we audited our own UX" blog post. The iframe embed format is on the roadmap.
