Div/Sum

About this app

Div/Sum is an AI-powered bill splitting app designed to eliminate the awkwardness and hassle of dividing group expenses. Using advanced OCR and AI technology, it scans and reads physical receipts, automatically identifies line items, and calculates fair splits based on what each person actually ordered. The app helps users track who owes what and facilitates getting paid back quickly. It targets friend groups, roommates, travelers, and coworkers who frequently share meals and expenses. By automating the traditionally tedious process of manually splitting bills, Div/Sum aims to complete the entire process in under a minute, reducing social friction and mental math errors.

Scout Review

Written by AI from measured evidence, scored out of 100.

Div/Sum is an AI bill-splitting app that scans receipts, identifies line items, and calculates fair splits based on what each person actually ordered. The concept is strong: it targets a real, universal annoyance — the post-dinner math scramble — and aims to compress it into under a minute. The problem is that the live product could not be evaluated. The homepage returned only an error state, so design, onboarding, pricing and documentation are all unverified. What could be measured is mixed: desktop performance is good at 84/100, but mobile LCP of 12.8 seconds is a serious red flag for a mobile-first use case. Security headers are mostly in place (9/12) with HTTPS and HSTS enforced, though CSP and DMARC are missing. Accessibility is a solid 93/100 with two minor failures. Growth potential is real but faces entrenched competition from Splitwise, Venmo and Settle Up.

Measure by measure

Usability

Onboarding, signup and docs could not be evaluated because the only fetched page was an error screen. No pricing, demo or help content was reachable to confirm the under-a-minute claim.

Design

No live UI or screenshot could be captured, so design is judged from the product's positioning alone. The receipt-scanning concept is clear, but visual execution is unverified.

Speed

Lighthouse mobile 63/100 with a brutal 12.8s LCP and 4.4s FCP; desktop is a healthier 84/100. Mobile users wait an eternity for first paint, which undercuts the 'under a minute' pitch.

Security

HTTPS enforced with HSTS, frame protection and most hardening headers present (9/12). Missing CSP and DMARC, and no SOC 2, ISO or pen-test claims were found.

Accessibility

Lighthouse accessibility 93/100 with two real failures: insufficient color contrast and a missing main landmark. No a11y statement or keyboard-navigation documentation was found.

Growth

Real problem (awkward bill splitting), specific wedge (OCR itemized splits for travelers and roommates), but Splitwise, Venmo and Settle Up already own the category with far more reach.

Improvement areas

Homepage currently returns only a 'Can't load Div/Sum' error, making the product unevaluable.
Mobile Lighthouse performance 63/100 with a 12.8s LCP, contradicting the under-a-minute promise.
Missing Content-Security-Policy and DMARC headers; no SOC 2, ISO or pen-test claims published.
Lighthouse accessibility failures: insufficient color contrast and missing main landmark.

Design & Usability

Design and usability both suffer from the same problem: nothing could be inspected. The homepage returned only an error state, so there is no signup flow, no pricing page, no demo, and no screenshot to judge. The product's pitch — scan a receipt, split by line item, settle in under a minute — is genuinely appealing and clearly articulated in the description, but the live experience is unverifiable. For a tool whose entire value proposition is speed and friction reduction, an unreachable homepage is the worst possible first impression. Until the site loads reliably, neither design polish nor onboarding quality can be assessed, and both scores sit in the category-typical band on the strength of the concept alone, not the execution.

Speed & Security

Speed is a tale of two platforms. Desktop Lighthouse lands at a respectable 84/100, but mobile collapses to 63/100 with a 12.8-second Largest Contentful Paint and 4.4-second First Contentful Paint. For an app that promises to finish a bill split in under a minute, making mobile users wait nearly thirteen seconds before anything meaningful renders is a direct contradiction of the pitch. Security is stronger: HTTPS is enforced with HSTS, and frame protection, X-Content-Type-Options, Referrer-Policy and Permissions-Policy are all present, giving a 9/12 header checklist score. The gaps are a missing Content-Security-Policy and no DMARC record. No SOC 2, ISO 27001 or penetration-test claims were found, which is normal for an early-stage product but leaves compliance verification entirely on the user's trust.

Accessibility & Growth

Accessibility scores 93/100 on Lighthouse, which is genuinely strong, but two real failures remain: insufficient color contrast and a missing main landmark. Neither is fatal, but both are easy fixes that signal the audit was run and partially ignored. No accessibility statement, keyboard-navigation notes or multi-language support were found, so the broader WCAG picture is incomplete. Growth is a judgment on the idea: splitting group expenses is a real, recurring pain, and OCR-based itemized splitting is a sharper wedge than the manual entry Splitwise and Settle Up rely on. But the category is crowded — Splitwise owns the habit, Venmo owns the payment rail, and Settle Up owns the lightweight tracker niche. Div/Sum's differentiator is real but narrow, and the domain is only about 0.4 years old with a single Instagram profile as its social footprint. The idea can grow; the execution has to catch up first.

Conclusion

Div/Sum has the right instinct: receipt scanning plus itemized splitting is a smarter wedge than yet another manual expense tracker, and the under-a-minute promise is exactly the kind of concrete claim users can evaluate. But a product that cannot load its own homepage cannot deliver on any of it. The immediate priorities are unglamorous: get the site reliably online, fix the 12.8-second mobile LCP, add a CSP and DMARC record, and resolve the two accessibility failures. After that, the harder work begins — proving that OCR accuracy is good enough to trust with real receipts, and that the itemized-split workflow is meaningfully faster than Splitwise's manual entry. The idea deserves a fair shot. Right now it is not getting one.

Suggestions for improvement

Fix the homepage loading failure — a retry error screen as the only live content makes the product unevaluable.
Cut mobile LCP from 12.8s toward the 2.5s 'good' threshold; mobile is the primary use case for receipt scanning.
Add a Content-Security-Policy header and a DMARC record to close the two remaining security gaps.
Resolve the Lighthouse contrast and main-landmark failures, and publish a short accessibility statement.
