From month 12 you can buy it, applying 50% of the fees paid as credit.

Website payments: 50% upfront to start and 50% against the published site. A 60-day bug-fix warranty on build errors.

Custom apps

Your own app on the App Store and Google Play

Or rented: your app with no big upfront investment

The same brand-new app, paid monthly with everything included: maintenance, hosting and publication. The app lives under Eternity's accounts while the service lasts, and from month 12 you can buy it, applying 50% of the rent paid as credit.

  • Basic, rented — US$299/month (setup US$399, 12-month minimum)
  • Business, rented — US$549/month (setup US$799, 12-month minimum)

Maintenance for purchased apps: Essential US$149/month · Professional US$299/month · Premium US$499/month — store compatibility, bug fixes and adjustment hours depending on the plan.

Prefer no contract? That works too

App rental and website-as-a-service are also available month to month, with no lock-in: cancel whenever you want, with no penalty, and the service stays active until the end of the period already paid. Without a contract, setup and monthly fees are a bit higher, and the purchase-with-credit option belongs only to the contract version.

  • Basic App, no contract — US$399/month (setup US$799)
  • Business App, no contract — US$649/month (setup US$1,299)
  • Website as a service, no contract — from US$129/month (setup US$199)

Clear terms, in writing

  • Milestone payments: 50% at signing, 25% with the working demo and 25% against approved publication in the stores.
  • If a store rejects the app over something fixable within the scope, we fix it and resubmit at no cost until it's approved.
  • A 60-day warranty covering build-error fixes after publication.
  • Out-of-scope changes: US$75/hour, quoted and approved in writing before they're done.
  • A 5-step process: consultation and quote in 48 hours → contract and deposit → design approved by you → build with weekly demos on your phone → publication and handover.
  • Not included: the client's store accounts (Apple US$99/year · Google US$25 one-time), content (texts, photos and logo are provided by the client) or third-party fees.
