No. LifeShack automatically answers and submits supported applications using the information in your profile, preferences, and reusable answers. There is no per-application approval or review step before submission.
You can manage the automated workflow by pausing Auto Apply before the next run and maintaining a Company Blocklist for employers you want to exclude. Read those guides for limits: neither control withdraws applications already submitted or guarantees recall of one already in progress.
If you need to inspect and approve each application yourself, applying manually on employer career sites is a separate option.
