IFS journaling apps compared

GoodParts

A voice journal that journals back. You talk, freely, with nothing to pick first. GoodParts transcribes what you said and reads the transcript for the parts that are speaking. It recognizes a part when it comes back in a later entry, suggests merging two parts that look like the same one (you can accept, or undo), and lets you ask your journal a question and answers it only from your own entries. There are no streaks; here's why.

Typing is for unsent letters and for importing writing you already have. If you want a journal you mostly type into day to day, this isn't it.

Your first five entries are free, with no clock on them. After that it is $4.99 a month or $34.99 a year, the lowest price in this set. If you stop paying, your entries stay and export is never gated.

Your recording is transcribed in the cloud by AssemblyAI, through its EU endpoint; AssemblyAI is set to delete leftover data one day after each request. The analysis that names your parts runs on Amazon Bedrock in the US and works from the transcript text, never the audio. Data is encrypted in transit and at rest, and your journal is not used to train AI models.

You can lock the app, export your data (the export leaves out audio files), or delete your account and everything in it. Your data has the detail.

iPhone (iOS 18 or later) and Android. English only.

All My Parts: IFS Journal

The closest app to ours. All My Parts detects parts in real time as you write, and gives each one a card with its role (manager, firefighter or exile), its traits and its history. You can type or, on Pro, talk and have it transcribed. Pro also adds a weekly synthesis on Saturdays and “Ask All My Parts”, a search across your own entries.

The free tier offers limited daily journaling, basic entry analysis and parts detection. Pro is $12.99 a month or $99.99 a year in the App Store, with a 7-day trial; the website shows the monthly price with a “Save 36%” annual toggle.

Its site says entries are encrypted in transit and at rest, never sold and never used to train AI, and you can export any time. The App Store label lists purchase history, email, audio data, other user content and a user ID as linked to you.

iPhone and Android; no iPad. It is new too: version 1.0.5, with 3 App Store ratings at 2.7★.

Parts: An IFS Companion

A quieter, more structured app. You pick a feeling, go through a guided conversation of about five minutes, and finish with a letter written “from that part”. Its listing describes a map that takes shape as you go, but you choose the part; the app doesn't find it for you. Text only, with streaks and badges.

Its strongest point is privacy. The policy says entries stay on your phone and there are no servers; only the part label and the prompt text go to Anthropic's API. We noticed the App Store label declares Health, Name and User Content as collected (though not linked to you), which doesn't quite match the policy.

There's a 7-day free trial, then $9.99 a month or $49.99 a year. We couldn't confirm whether anything stays free after the trial. iPhone only; we found no Android listing. 14 ratings, 4.5★.

IFS Guide

The established option, with by far the most ratings. IFS Guide is built around an AI guide called Sunny, which you can text or talk to; the listing says the conversation works in any language, though the app itself is in English. After a session Sunny creates a parts map for you, and you can also keep part profiles by hand. It includes audio meditations, and runs on iPhone, Android and the web.

The download is free. Paid plans come in several overlapping tiers: Premium at $14.99 a month or $95.99 a year, and Platinum at $19.99 to $29.99 a month or $99.99 to $159.99 a year. We couldn't confirm what the free tier includes today.

Its two store listings disagree. The App Store label says identifiers are used to track you, and lists email and device ID as linked to you, and for personalization also name. The Google Play listing says no data is collected and that data isn't encrypted.

819 App Store ratings at 4.8★, and 562 Play reviews at 4.4★ with over 10,000 downloads. If track record matters most to you, nothing else here is close.

InnerOS: IFS Parts App

InnerOS isn't really a parts-detection journal in the IFS sense. Its “Inner Council” is ten fixed archetypes drawn from Jung (Warrior, Lover, Sage and others) that respond to what you write. It is text first, says it speaks and listens in eight languages, and adds mood tracking, a weekly summary, and a note when you seem to have been somewhere before.

It is the only app here, apart from Internal Family, that runs on iPad, and it also has Android. There's a 14-day free trial, then $19.99 a month or $79.99 a year; every feature needs the subscription.

The listing says your data is encrypted and never sold, with a Face ID lock and export or delete at any time. The App Store label lists email, name, user ID, device ID and crash data as linked to you. It has one App Store rating.

Internal Family: Parts Journal

The baseline: its listing doesn't mention AI. You create and map your parts by hand, with check-ins and a journal. If you want to do the noticing yourself, and want an app whose store label says it collects no data, this is the simplest answer here. Its App Store label reads “Data Not Collected”.

Free to download; a subscription unlocks unlimited parts mapping at $39.99 a year, or $6.99 a month. iPhone and iPad; we found no Android listing. 9 ratings, 4.1★.
