A self-criticism app your therapist can actually reference in your next session

When your client describes their week, ask yourself: what were they actually thinking at 2pm Tuesday? Mendly is a self-criticism tracker for iPhone that produces a log therapists can reference — weekly pattern reports, hourly distribution charts, and optional voice notes. Clients tap once to mark a self-critical thought in the moment. The data arrives at the next session.

The research

Daniel Kahneman's peak-end research found that people's retrospective account of an experience is shaped disproportionately by its most intense moment and its ending — not the full timeline. A client's 'the week was hard' summary in session is subject to the same bias. Mendly's weekly report is the un-summarized version: every logged moment, not just the peak.

— Daniel Kahneman, peak-end rule research, 1999

Quiz

What's your self-criticism's pattern?

Question 1 of 4

When summarizing a hard week, what sticks out most?

“The session narrative was never the full data set. It was always a compressed, peak-weighted highlight reel — and most therapists have never seen what the uncompressed version looks like until now.”

Features

Hourly patterns

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

Weekly reports

A gentle summary of your week. Not a grade — just a window into your patterns.

Shareable cards

Daily summary cards designed for Stories. Share a win without oversharing.

Not quite your pattern? A self-esteem tracker that shows when the dips happen, not just that they do might fit better

Apps like MindLift ask clients to complete CBT thought records in the moment — a higher-friction interaction that requires more engagement than a self-critical episode may allow. Mendly's single-tap log is more likely to be used in the moments that matter, which produces more complete data for the session.

Common questions

How does my client share Mendly data with me in session?
Clients can export their log as a CSV from the settings menu — dates, times, and any voice note transcripts. The weekly report is accessible in the app and can be screenshotted or discussed directly. There's no direct therapist-facing portal currently.
Will my client actually use it between sessions?
The friction is designed to be as low as possible: one tap, optional voice note, no prompts to answer. The milestone system rewards the act of logging, not the quality of each entry. Clients who find journaling too demanding often find Mendly sustainable — the minimum viable entry is a tap.
Is Mendly a clinical tool?
No. Mendly is not a medical device and is not validated as a clinical assessment tool. It's a consumer logging app that produces self-reported pattern data. It's most useful as a between-session awareness aid, not a diagnostic or treatment instrument.
What does the free trial include?
The full app, no restrictions, for 7 days. After 7 days clients choose monthly ($7.99) or annual ($59.99, about $5/month). Cancel anytime via Apple subscriptions — no emails required.
