An overthinking tracker that shows your mind's pattern, not just its noise

Overthinking has a shape. Mendly lets you tap once to log an overthinking episode on iPhone — no journaling, no exercises required. Hourly pattern charts show when your mind runs hardest: mornings, late nights, specific days of the week. Milestones track the awareness habit. No reframing prompts, no daily check-ins. Just data about a mind that thinks a lot.

The research

The Zeigarnik effect explains why unfinished thoughts intrude more persistently than resolved ones — Mendly's tap-to-log doesn't resolve the thought; it gives an overthinking mind a place to set it down without finishing it.

— Bluma Zeigarnik, 1927

Quiz

What's your overthinking pattern?

Question 1 of 4

What usually kicks off a spiral?

“Overthinking isn't a thinking problem. It's an unfinished-business problem — and the fix isn't fewer thoughts, it's a place to set the unfinished ones down.”

Features

Hourly patterns

See when your inner critic is loudest. Morning spirals? Late-night overthinking? Your data, your story.

One-tap logging

One tap marks the thought — no typing, no prompts. The friction is so low it actually works mid-meeting, mid-walk, mid-spiral.

Voice notes

15 seconds to say what was actually going through your head. Optional, private, and yours.

Not quite your pattern? A tracker for the running commentary about your body you never signed up for might fit better

CBT apps like MindLift ask you to identify and reframe the thought as you log it — for an overthinker, that's one more thing the mind has to chew on. Mendly just takes the timestamp, no structured response required.

Common questions

What's the difference between logging an overthinking episode and just thinking about thinking?
The act of logging creates a small shift in position — you're the observer marking the episode, not the episode itself. You don't analyze it; you timestamp it. Over time, those timestamps become data, and the data tells you things introspection doesn't.
Is this a CBT app?
Mendly is informed by awareness-based approaches but doesn't guide you through cognitive restructuring. There are no thinking-trap labels, no thought records, no reframing exercises. If you're looking for structured CBT tools, a different app may suit you better.
Do I need to log every episode to get useful data?
No. Even catching some of them builds a meaningful picture over time. There's no streak penalty for missing days, and no feature requires perfect logging to work. Partial data is still data.
What does the free trial include?
The full app, no restrictions, for 7 days. After 7 days you choose monthly ($7.99) or annual ($59.99, about $5/month). Cancel anytime via your Apple subscriptions — no emails required.
