The personal strategy app

Believe it. Behave it. Become it.

B3 turns what you want into goals you check in on, and goals into everyday actions and habits. It keeps the people who back you, and the money behind it all, in one place.

How B3 works

Three words. One way to get there.

Scroll down and the picture draws itself, the way a plan comes together: the goal first, then the path, then what you grow into.

Step 1

Believe

Decide what you want and why it matters. A B3 goal has a target, a due date and a check-in rhythm, plus the reasons that keep you going.

  • Benefits, a reward and a consequence for every goal
  • Start from 274 templates, or let the AI Goal Builder draft one
Step 2

Behave

Turn the goal into steps you'll actually take: one-off actions with subtasks and reminders, and recurring actions for your habits.

  • Assign work to supporters and ask them to approve it
  • Reminders before things are due, and at the hour you choose
Step 3

Become

Check in on your rhythm and watch the picture change. B3 tells you what's on track and charts your progress.

  • On track or off track, worked out for you
  • Progress charts, and a budget that funds the plan

Everything in B3

Your goals, your habits, your people, your money.

Each part works alone and is better together. Every one of them is below.

Recurring actions Pro

Set a routine once and B3 creates the action every day, week, month or year, ready to tick off.

Approvals

Name an approver and "done" needs their sign-off. Rejections come with a note, and you can always resubmit.

Supporters

Invite the people who back you. Share goals, actions and budget categories one at a time, and choose who does what.

Budget and money

Accounts, categories, transactions and a monthly budget, so your plans and your money finally live in one place.

Questions

The short version

What is B3?

B3 (Believe Behave Become) is a personal strategy app for Android and iPhone. You set goals and check in on them at your own rhythm, and break them into one-off and recurring actions. You invite supporters to keep you accountable, and you track the money behind it all: accounts, transactions, a monthly budget and reports.

What does "Believe Behave Become" mean?

It's how change happens. Believe: decide what you want and why it matters. Behave: turn it into actions and habits you actually do. Become: check in, see your progress, and become the person who got it done.

Is B3 free?

Yes. The Free plan has no time limit and includes goals, actions, the Goals Library, supporters, approvals and a budget, within limits: 2 active goals, 2 active actions, 1 money account and 15 transactions a month. B3 Pro removes those limits and adds recurring actions, the AI Goal Builder, Budget Mode, repeating transactions and PDF reports.

Which devices does B3 work on?

Android phones and tablets running Android 7.0 or later (from Google Play), and iPhone (from the App Store). One account works on both. There is no web app: you use B3 in the mobile app.
