Chrono
Read full descriptionHide full description
**Your brain is full. Chrono takes the load off.** You don't need another to-do list. You need a system β one place where your notes, daily routines, and long-term goals work together instead of living in separate apps you forget to open. Chrono is a productivity app built by someone who kept forgetting things, losing notes, and ignoring reminders. It's designed around one idea: if the tool isn't fast and frictionless, you won't use it. **NOTES THAT ACTUALLY WORK** Capture thoughts instantly. Tag them with one tap. Find them later without scrolling through chaos. No folders, no nested hierarchies β just fast, clean note-taking that stays out of your way. **ROUTINES THAT STICK** Morning exercises. Supplements. Language practice. Set it once, and Chrono reminds you β not just once, but repeatedly until you actually do it. Missed the 9 AM reminder? Get another at 9:30. And 10:00. Your routine doesn't care about your excuses, and neither does Chrono. **GOALS WITH SESSIONS** Reading. Studying. Deep work. These aren't tasks you check off β they're activities you build over time. Set a session length, get a notification when it ends, and decide: one more round, or done for today? No more forgotten timers running for 14 hours. **AI ASSISTANT β YOUR NOTES AS CONTEXT** Connect your own API key and let AI work with your actual notes. Summarize, translate, rewrite, or brainstorm β with your own data as context. Your notes become a knowledge base, not just a pile of text. **100% OFFLINE. 100% PRIVATE.** Everything is stored on your device. No cloud sync, no account required, no data harvesting. Your thoughts stay yours. **WHY CHRONO?** - Not a planner. Not a to-do app. A productivity system. - Built for speed: open β write β done. - Smart recurring reminders that won't let you slip. - Session-based goal tracking for long-term activities. - AI that actually knows your context. - Offline-first. No sign-up. No cloud. Stop planning to be productive. Start being productive. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is in-app purchases: OpenShell at none against Chrono's 4. OpenShell also leads on update cadence (every 3 days vs every 5 weeks). Chrono's advantage is iOS requirement (14.0 vs 26.0). On price, ads and device support there is nothing between them.
