A self-doubt tracker for the voice that shows up whenever something matters

When the stakes are high, the voice gets louder. Mendly tracks self-doubt on iPhone — one tap per episode, no reflection required. Hourly patterns show when doubt spikes relative to work events and high-pressure moments. Milestones reward the act of noticing. It's a performance-awareness tool built for people who don't think they need a wellness app.

The research

Psychologists distinguish 'trait' self-esteem (stable, general) from 'state' self-esteem — the version that spikes and crashes around specific events. Most self-doubt is a state phenomenon, not a trait one, which is exactly what Mendly's hourly pattern data is built to reveal.

— Heatherton and Polivy, 1991

Quiz

Not quite your pattern? A tracker for the feeling that no result ever quite closes might fit better

Apps like MindLift are built around restructuring self-critical thoughts when they appear. For high-stakes self-doubt, that restructuring adds a step to an already-loaded moment. Mendly logs the thought without asking you to respond to it.

Common questions

What if I only feel self-doubt in specific situations — is the app still useful?
That specificity is exactly what makes it useful. Situational self-doubt is easier to track than diffuse anxiety — you'll see patterns around specific contexts (presentations, feedback conversations, high-visibility work) within a few weeks. The data reveals whether the trigger is consistent or shifting.
Is this a therapy app?
No. Mendly isn't a therapeutic intervention and doesn't guide you through structured exercises. It's a logging tool. If you're looking for CBT or coaching support, a therapist or coach would be more appropriate alongside the tracking.
Does it work on Android?
Not yet — Mendly is iPhone only. An Android version is on the roadmap but doesn't have a release date.
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.
