On Turning 35

December 15, 2025 • 847 words

Thirty-five feels different than I expected. Not in a bad way — just... quieter. The urgency I felt in my twenties has softened into something more sustainable. I've learned that consistency beats intensity, and that showing up matters more than grand gestures.

This year I ran 200+ days. I meditated more days than not. I wrote in my journal every week. Small things, but they add up. The compound interest of tiny habits is real.

Here's to another year of showing up.

Privacy by design.

Your data is encrypted before it leaves your device. We never see your plaintext. Even if someone hacked us — or seized our servers — your habits, goals, and reflections would remain a mystery.

  • Zero-knowledge — we can't read your data

  • Quantum-resistant — hybrid post-quantum key encapsulation

  • Three encryption layers — client, application, infrastructure

  • Free on every plan — privacy isn't a premium feature

Every plan

Your data. Your way out.

Export everything you've built — habits, goals, reflections, journal entries, calendar events — in the format you need. Decrypted client-side, downloaded to your device. No lock-in, ever.

  • JSON export — structured backup of all your data with relationships preserved

  • CSV export — spreadsheet-friendly zipped archive, one file per domain

  • .ics calendar — import & export events to Google Calendar, Apple Calendar, Outlook, and Fantastical

  • Printable planner — print your calendar month grid, day timeline, or two-column notebook layout

  • Zero-knowledge preserved — decryption happens in your browser, we never see plaintext

Evidence-based

Built on behavioral science.

Every feature is informed by peer-reviewed research on habit formation, goal pursuit, and self-determination. This isn't guesswork — it's how behavior change actually works.

Habit Stacking

"After I..." contextual cues anchor new habits to existing routines — the strongest behavior change technique known (d=0.65).

66-Day Automaticity

A habit strength indicator shows where you are on the formation curve — research shows habits become automatic around 66 days.

Context-Aware Prompts

Reflection prompts adapt to your state — streak breaks, mood dips, milestones — because tailored interventions outperform generic ones by 30–50%.

WOOP Goal Method

Confidence rating + obstacle identification on goals — Mental Contrasting with Implementation Intentions outperforms positive thinking by 2–3x.

One-Tap Check-In

Check in directly from push notifications on supported devices — every second of friction between cue and action reduces follow-through.

Variable Reward

Streak milestones, micro-celebrations, and achievements deliver unexpected positive feedback — the most engaging reinforcement schedule.

Based on research by Lally et al., Gollwitzer, Oettingen, Fogg, Deci & Ryan, and others. See our about page for references.
