Stop losing hours to the scroll. DoomShield locks the apps that hijack your attention—Instagram, TikTok, X, and more—until you earn them back with real push-ups. HOW IT WORKS 1. Pick the apps that drain you. 2. Open one and DoomShield's shield blocks it. 3. Do your push-ups—the AI camera counts every rep. 4. Earn a timed unlock. When it's up, the shield comes back. It's a simple trade: move your body, get your time. No willpower required—just a rule you can't swipe away. REAL, UN-BYPASSABLE BLOCKING DoomShield uses Apple's Screen Time technology to block apps at the system level. This isn't a timer you can dismiss—it's a real shield. EARN IT WITH EFFORT Turn doomscrolling into reps. Every unlock costs a few push-ups, so the more you reach for your phone, the stronger you get. SQUAD: STREAKS WITH FRIENDS Add friends, build daily streaks, and keep each other honest. Nudge your squad when they slack—accountability is the cheat code. TRACK YOUR PROGRESS See your push-ups, unlocks, and streaks over time. Watch wasted hours turn into reps. DOOMSHIELD PRO Upgrade for unlimited blocked apps, unlimited daily unlocks, custom rep and session targets, and full stats. Beat the doomscroll. Build the habit. Get your time back—one rep at a time.

Verdict
The clearest difference is rating: DoomShield at 5.0 against Kaivoo's 4.1. DoomShield also leads on update cadence (every 4 days vs fortnightly). Kaivoo's advantage is ads (none vs shown) and ratings volume (15 vs 2). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Kaivoo sells 3 in-app purchases, starting at $9.99 per month and DoomShield sells 3 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.
DoomShield holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: Kaivoo has 15 ratings behind it against 2, so its average is the more settled of the two.
Kaivoo ships an update fortnightly, DoomShield every 4 days. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
