4. ⚖️ FairSplit
Document. Communicate. Co-parent with clarity.
A co-parenting documentation platform for separated parents 30-55 — a modern, dad-friendly alternative to OurFamilyWizard. Two co-parents pair into a shared CASE: every message, custody event, expense and document is stored with a server-side immutable timestamp and a sha256 content hash (tamper-evident, write-once). An AI tone checker rewrites a heated draft into a neutral, child-focused version before it sends. A shared custody calendar takes mutual-approval changes and one-tap proof-of-presence check-ins (time, GPS, photo) that build a printable Dad-Activity Log. The expense tracker scans receipts (kept as evidence) and shows a transparent contribution fairness ratio. A tamper-evident document vault holds court orders and records. An anonymous, AI-moderated community supports divorced parents. 7-day full trial, then $12.99/mo or $99/yr per parent — two-way features need both parents active; the read-only calendar always stays visible. Sold through family-law attorneys, not app-store ads. Legal Blueprint look: navy + gold, graph-paper grid, Lora serif, sharp document-grade cards.
- Immutable, hash-verified message & event ledger
- AI tone check rewrites heated drafts before sending
- Proof-of-presence check-ins (time + GPS + photo)
- Receipt scanning + transparent expense fairness score
5. 🛠️ HomeCraft
Build. Maintain. Track your gains.
A home maintenance & project OS for men 30-55 — the Strava for your house. Existing home apps (HomeZada, Centriq) feel like chore lists; HomeCraft is hobby-coded. Each project is a rich BUILD THREAD — photos, notes, materials, hours, costs — the productized forum thread men already love. A gamified seasonal maintenance checklist (change the HVAC filter, clean gutters, flush the water heater) keeps an on-time STREAK; Plus regenerates an AI calendar tailored to your home type, climate and system ages. A home-value dashboard tracks equity and frames total project spend as ROI. Snap a receipt and AI logs the expense; describe a project and AI estimates cost, time and a materials list; long threads get an AI summary for sharing in the community workshop. Free: 1 active project, 3 reminders, basic expenses, read-only community. HomeCraft Plus $12.99/mo or $99/yr: unlimited projects, full AI calendar, budget dashboard, posting, export. Workshop Blueprint look: navy grid paper, safety orange, pegboard hang-tag cards.
- Projects as photo build threads (the core)
- Gamified seasonal maintenance streaks
- AI cost estimates + receipt scanning
- Home value & ROI dashboard
