Stop counting seconds. Start seeing time. Aestu is a visual focus timer that turns time into a calm, fluid shape. Instead of watching numbers tick down, you can understand your session at a glance and stay focused without the pressure of a conventional countdown. DESIGNED FOR THE WAY YOUR MIND WORKS - Visual time: See time gently empty and refill instead of doing mental math. - Positive Overtime: When a session ends, Aestu keeps counting up without a jarring failure state. - Made for people who struggle to feel time: A clear, low-pressure visual cue, the kind many people with ADHD look for. - Pomodoro and deep work: Choose a preset or create a session that fits your own rhythm. - Energy check-ins: Log how you feel and learn which times of day work best for you. - First small step: Write how to start and Aestu quietly keeps it in view during the session. - Realistic durations: After a few sessions, Aestu suggests the typical length of a task and never changes your timer on its own. - Pressure-free sessions: No red final minute, extra time in a neutral color and gentler notifications. FOCUS EVERYWHERE Start on iPhone, check a Live Activity or widget, and pause, resume or add time from Apple Watch — iPhone and Watch share the session in progress. iCloud keeps your session history in sync across your Apple devices, including Mac. CALM BY DESIGN Fluid animation, semantic colors and gentle haptics provide awareness without a ticking clock or harsh alarm. Your history helps you notice patterns without turning productivity into a scorecard. FREE, WITH OPTIONAL PRO The timer is free to use. Aestu Pro is a one-time purchase, no subscription: it unlocks your full history, Insights and Calendar export. PRIVATE BY DEFAULT No account and no behavioral advertising. Your focus data remains on your devices and in your personal iCloud.

Download Aestu and turn time into something you can feel.

Verdict
The clearest difference is in-app purchases: Diadu at none against Aestu's 1. Diadu also leads on update cadence (every 3 weeks vs every 6 weeks). Aestu's advantage is device support (4 vs 2) and iOS requirement (18.6 vs 26.5). On price and ads there is nothing between them.
