On-device AI app that splits shared subscriptions fairly using Screen Time usage data — so your roommate who watches 80% of Netflix pays 80%, not 50%.

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.
Monetization model, marketing strategy, and the #1 complaint from users for each.
$400K/mo
Free (3 transactions/day with 10-sec delay), Splitwise Pro ~$3.99-4.99/mo for OCR, cloud receipts, currency conversion.
10+ years of App Store placement, word-of-mouth, strong brand recognition. #76 free finance, #23 revenue ranking.
Daily transaction limits (3/day) deliberately designed to frustrate free users into upgrading; no built-in payment settlement; messy payout lists; equal splits only — no usage weighting.
Unverified
Free basic co-subscription management, Premium for messaging, payment transfers, analytics. 950K users primarily EU.
Europe-focused; influencer marketing, TikTok presence. Strong EU traction but limited US presence.
Regional limitations (mostly EU); subscription-only focus doesn't handle mixed expenses (utilities, groceries); limited U.S. availability.
Unverified (early stage)
Free basic, Shaggle Pro lifetime $7.99 or yearly $3.99. Privacy-first (no data collection, stays on device).
App Store optimization, word-of-mouth. Newest entrant validating one-time purchase + privacy-first model.
Too new to have meaningful user reviews; limited feature set; no clear differentiation vs Splitwise beyond privacy.
Unverified
Free photo-based bill splitting with itemization. Premium for cloud sync, group management.
Instagram, TikTok. Photo-first UX as differentiator for dining/travel splits.
Camera quality dependency; OCR errors on handwritten items; travel/dining focused — doesn't handle recurring subscriptions.
Unverified (low profile)
Free full bill splitting, one-time $4.99 for unlimited groups + Excel export. Works offline.
Word-of-mouth only; simplicity positioning. Minimal marketing investment.
Offline-first design limits real-time collaboration; near-zero brand awareness; unknown to most users.
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.

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 Risk | Biggest 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. |
Bundle ID and IAP product IDs must be created in App Store Connect first. Mismatches are the #1 cause of upload failures.
