The short version

  • Only AGI STK has a free tier, so it costs nothing to try first.
  • Each has a real cost: AGI STK sTK is sold as a ladder of separate licences, STK Pro, STK Premium Air, STK Premium Space and STK Enterprise, so mission areas are gated behind different products; Flighty it is iOS-only, so a mixed-platform household or an Android user cannot use it at all.
  • They diverge on capability: AGI STK covers Orbit analysis, Flighty covers Delay prediction.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

AGI STK

  • STK is sold as a ladder of separate licences, STK Pro, STK Premium Air, STK Premium Space and STK Enterprise, so mission areas are gated behind different products
  • Further capability is sold as separate add-on toolkits including TETK, the RF Channel Modeler and the STK Missile Toolkit
  • Distributing an application built on STK Engine to end users requires each of them to hold an Ansys STK Engine Runtime License
  • Free access is limited to students at accredited institutions and to time-limited trials
  • No price, minimum or cost driver is published for any STK tier

Flighty

  • It is iOS-only, so a mixed-platform household or an Android user cannot use it at all.
  • The free tier tracks very few flights, so anyone who flies more than occasionally is pushed toward the subscription almost immediately.
  • Delay predictions are a probability model, not a guarantee, and can be wrong in either direction.
  • It depends on the same underlying ADS-B and airline feeds as free trackers, so the raw position data is not exclusive to Flighty.
  • A lifetime purchase is expensive relative to a year or two of the annual plan, so it only pays off for someone certain they will use it for years.
