How much does LINE make per month?

Based on our ML-calibrated revenue forecast, LINE earns approximately $700K/mo. This is a US-storefront-equivalent estimate; global revenue can be several times larger for internationally-distributed apps. See the methodology page for the full formula and confidence bands.

With estimated build cost $245K and monthly revenue $700K, LINE looks highly profitable — pays back its build investment in under a month at the current run-rate. Profitability also depends on paid-acquisition spend and refund rate which the public model doesn't see.

How many users does LINE have?

Estimated audience: ~914.0M lifetime downloads, ~56.0M monthly active users, and ~33.5M daily active users. Derived from ratings count × category installs-per-rating × age decay. US-storefront-equivalent — global audience can be 5-10× larger for internationally-distributed apps.

✍️ Bumetric analysis

“

LINE targets the broad communication app market, directly competing with giants like WhatsApp and Messenger by offering free voice, video, and text alongside unique sticker features. Its substantial user base, evidenced by over thirteen million ratings, indicates significant traction and a mature product, despite a mid-three-star rating which suggests some user friction or unmet expectations. This app is well past its growth phase and firmly established. For free communication apps in this category, monetization often leans heavily into in-app purchases for digital goods like stickers and themes, or premium subscriptions for enhanced features, rather than direct ad revenue which can degrade user experience. Observing the success of sticker packs here suggests a strong potential for expanding digital collectible offerings.

BU Score 71 · Strong — healthy traction. The full Investment Matrix below scores 8 dimensions including monetisation, growth, and operational risk.
