Take control of your screen time with Otama, an app blocker, focus timer, social media limiter, and digital wellbeing companion designed to help you use your phone with intention. Instead of instantly opening distracting apps, Otama adds a thoughtful pause before they launch. Brain Games act as your shield between you and your distraction, giving you a real opportunity to decide whether using them is worth your time. Rather than relying on simple app blocks that are easy to disable, Otama makes access a deliberate choice. Choose the apps you want to control, select an unlock challenge, adjust the difficulty, and decide how long you can use an app after completing it. Daily screen time allowances let you set a shared limit across locked apps or create individual limits for each one. Unlock durations have limited daily uses, so every session becomes a more intentional decision. When you finish using an app early, Otama can return your unused time to Saved Allowance. Use that saved time later when it matters most, rewarding intentional use instead of encouraging longer sessions. After each unlocked session, an optional cooldown temporarily locks the app again, helping prevent repeated open-close-reopen habits that often lead to unnecessary screen time. #Features • Block distracting apps with customizable unlock challenges • Set daily screen time limits for individual apps or groups of apps • Choose how long each unlock lasts with limited daily unlocks • Recover unused time with Saved Allowance • Add cooldown periods between sessions to discourage repeated checking • Create Routines for work, study, mornings, evenings, or bedtime • Start Focus Sessions with customizable timers and distraction-free app blocking • Use Urge Support for short guided exercises when you're tempted to open an app • Track attempts, resisted urges, intentional unlocks, time saved, and weekly trends • Switch between Casual Mode for flexibility or Committed Mode for stronger accountability • Adaptive app screen limits, let otama study your usage and help you reduce your screen time Otama is built for students who want to study without constant interruptions, professionals protecting deep work, creators trying to stay present, parents building healthier phone habits, and anyone tired of opening social media without thinking. It isn't about abandoning useful apps or chasing the lowest screen time possible. It's about creating enough friction to pause, make a conscious choice, and spend your attention where it matters most.

Verdict
The clearest difference is in-app purchases: Task Block at none against Screen Time Blocker's 2. Task Block also leads on iOS requirement (15.0 vs 18.5). Screen Time Blocker's advantage is update cadence (fortnightly vs every 4 months). On price, ads and device support there is nothing between them.
