Target User
Roommates/couples with separate Apple IDs sharing subscriptions

iOS 26.4 separated Family Sharing payment methods, creating a new friction point: how do roommates and partners split recurring subscription costs fairly? 85M+ US adults already use bill-splitting apps, but no app weighs fairness by actual usage. Subscription fatigue hit hard — users dropped from 9.1 to 7.3 active subscriptions — and one-time purchases are growing 6%. Splitwise dominates general bill splitting but frustrates users with daily limits and paywall tactics. The gap: usage-weighted subscription splitting with on-device privacy.

The gap: Usage-Weighted Fair Subscription Splitting

No existing app uses Screen Time data to weight subscription splits by actual usage. Splitwise only does equal splits. Spliiit is EU-only. iOS 26.4 just created a fresh cohort of users with separate Apple IDs who need to split shared subscriptions fairly. The gap: intelligent, privacy-first, usage-weighted splitting.

🟡 Overall: 7.8 / 10 — PAUSE

ShareTally has genuine, uncontested innovation (Screen Time usage weighting) and strong market tailwinds (iOS 26.4 payment separation, subscription fatigue). The $612M bill-splitting market is proven, and Splitwise's $400K/mo revenue validates willingness to pay. However, validation needed on: (1) Screen Time API accuracy for fair weighting, (2) whether 'usage-weighted' resonates with casual consumers, (3) competitive response timeline from Splitwise.

Biggest RiskBiggest Opportunity
Screen Time API access may be restricted in future iOS; Splitwise could add usage weighting in 1-2 releases; marketing 'usage-weighted fairness' may be too technical for casual users. iOS 26.4 timing creates fresh demand; Shaggle proved privacy + one-time model resonates; every user invites roommates (viral loop); subscription fatigue is the #1 consumer trend of 2026.
