Keep the apps free, forever.
Spark & Anvil makes 448 educational apps for Apple platforms (iPhone, iPad, Mac, and Apple Vision Pro) for kids and teens ages 3–18 — all free, no ads, no in-app purchases, no tracking. We can keep it that way because we're restructuring as a mission-driven non-profit.
Donations aren’t open yet. We’re finalizing fiscal sponsorship (Hack Foundation expected); once it’s in place, giving opens and is tax-deductible through the sponsor’s EIN. Email us to be notified →
Recurring monthly
💡 Our platform currently runs at approximately $500/month minimum — across research & content production (AI-assisted, human-directed, reviewer-gated), infrastructure & hosting, and compliance & domains. ~20 Sustainer-tier donors at $25/mo — or ~50 Supporters at $10 — or ~100 Friends at $5 — covers it. Every recurring donor contributes directly to keeping 448 apps free for every kid, forever. See the full cost breakdown →

Teacher Network Sustainers
Sustain the platform that lets teachers keep 100% of their class fees. Our teacher network charges teachers nothing — no commission, no platform fee. Run at scale (the network launches Q1 2027), it is projected to cost ~$50K-$140K/yr to operate — covered by donors like you + foundation grants, never a cut of teacher fees. Your monthly gift directly funds background-check coverage, ForgeClassroom infrastructure, COPPA compliance, and parent-side discovery for live small-group classes ages 3–18.
Tax-deductible through our fiscal sponsor once sponsorship is in place, while IRS Form 1023 determination clears. Optional public recognition on this page (we'll never publish your name without consent).

Donation flow coming soon. We're finalizing fiscal sponsorship (Hack Foundation expected) to make donations immediately tax-deductible while our IRS Form 1023 determination clears (~12-18 months from filing). In the meantime, email hello@sparkanvil.org to be the first to know.
Email us about donating →Tax deductibility & transparency
- 501(c)(3) status: pending. We've filed (or are filing) IRS Form 1023. Typical determination period is ~191 days median, 12-18 months real-world.
- Fiscal sponsorship bridge: we're finalizing sponsorship (Hack Foundation / HCB or similar). Once it's in place, donations route through the sponsor's EIN and become tax-deductible while the 1023 determination clears.
- Annual report: we'll publish a public annual report covering revenue, expenses, kids reached, partners, board, and 2026 audit findings.
- No ads, no tracking, no sale of data: these don't change under non-profit status; they're load-bearing to the mission.
