NPS may be seen as the closest comparison to Life Cycle Funds, since it also adjusts asset allocation over time. However, the differences are structural. NPS is a retirement product with lock-ins and restrictions on withdrawal.
A Lifecycle Fund is an open-ended mutual fund which is built not just for retirement and can be used for other goals as well having varied target maturity years. There is no lock-in, the investor can exit at any time subject to applicable exit loads. In addition, the allocation in a Lifecycle Fund is tied to a target maturity year chosen by the investor, not to the investor's age.
