Mental
A private mood tracker and journal for iPhone
About Mental
Mental is a mood tracker and journal for iPhone built around quick, private check-ins. Each check-in is a feeling picked on a seven-by-seven grid of energy and pleasantness (49 feelings), an optional note you type or speak, and optional tags. The journal stays on your phone and in your private iCloud. Mental uses a language model in four linked places - tags, Memory, the evening wrap-up and Ask Mental - and the developer publishes how each one works under a stated rule: the model suggests, the code decides.
Because the four parts feed each other, Mental adds hard checks, such as requiring every memory to be tied to a quote that actually appears in your note. Content sent to these features is processed transiently by third-party AI providers, which the site discloses; the models are not named. Pricing is freemium: a free tier that does not expire covers check-ins, notes, voice input, the journal, trends, tags and the first week of wrap-ups, and Pro costs $7.99 a month or $49.99 a year, each with a 7-day free trial. These figures come from the vendor's Terms of use, as there is no pricing page.
You check in by choosing a feeling on the grid, then optionally add a note, typed or spoken, and tags. The site describes this as a ten-second check-in.
On Pro, the model proposes up to five tags for the note. A match with one of your existing tags lands on the entry; anything new waits until you approve it. Memory runs as two separate model calls. The first reads only the note and proposes claims, each with a quoted span of evidence; the second compares them with your nearest existing memories without seeing the note. Code checks that each quote really appears in the note before saving.
In the evening you can read a wrap-up, a short account of the day written from evidence that code assembles: today's check-ins in full and the previous seven days only as figures. When you need to think something through, Ask Mental lets you talk one situation through by voice or text, drawing on memories and check-ins that code selects.
- •Fast check-ins - A 49-feeling grid arranged by energy and pleasantness, with typed or spoken notes and tags, plus a journal, trends, calendar views, a mood clock, streaks and reminders.
- •Automatic tags (Pro) - The model proposes up to five tags per note for what influenced the mood, such as activities, topics, kinds of people or places. The prompt rules out clinical conditions and diagnoses.
- •Memory (Pro) - People, situations and patterns drawn from your notes, each tied to a quote. You can open the source check-in, edit a memory in place or ask Mental to forget it, and a forgotten claim is blocked from coming back.
- •Daily wrap-ups - A short AI-written account of each day, free for the first week and part of Pro after that. Up to three memories can be added as dated background, labelled so an unconfirmed pattern is not presented as fact.
- •Ask Mental (Pro) - A voice or text conversation about one situation, decision or disagreement. Code chooses the sources it sees, holds back any sentence containing a link or phone number you did not write, and keeps Mental's own replies from being stored as things you said.
- •The Wager and Apple Health (Pro) - Forecast your next-day mood and get an accuracy score, and optionally allow coarse Health context such as sleep, steps, daylight and workouts in the wrap-up.
Mental is for iPhone users who want a private mood journal for general wellness and self-reflection. The free tier suits people who want to log how they feel and look back at trends without paying. Pro is for people who write notes and want the app to track the people and themes in them, summarise each day and help them think through a decision.
It will also appeal to people wary of AI journaling, because the developer documents what the model may do and what leaves the phone, and you can correct or delete anything Memory records.
Limits worth knowing: Mental is iPhone only, the AI features send content to third-party AI providers for transient processing, and it is a wellness journal rather than medical advice.
