Do It First is an iPhone app blocker that locks Instagram, TikTok or any app you choose at a set time until you finish a real task you planned — read 10 pages, study 30 minutes, go for a run — and confirm it with a photo. Every mission earns XP, keeps your streak, unlocks medals and evolves a pixel-art companion through five worlds. Built on Apple Screen Time, no account, your data stays on your iPhone. Free to start; Pro adds up to 10 protected missions.
