Habits as promisesto younger-you.
Add one photo of your younger self. Every small promise you keep brings her a little more into focus — until, by Saturday, you can see her whole again. Miss a day and you're forgiven, never shamed. Watch her come back.

The truth about who you are
80%
of who you are was shaped before you turned seven.

The kid you were is still quietly running a lot of the show — how you rest, how you talk to yourself, what you think you're allowed to want. You can't go back and give her a different childhood. But you can show up for her now, one small promise at a time. That's what a habit really is here: proof to her that you came back.
You can't change the start. You can change who shows up now.
The mosaic
Add one photo.
Keep one promise.
Watch her come back.
Your childhood photo starts behind a soft veil. Each habit you keep today lifts a little more of it. Nothing to decode, no numbers to chase — you just see her, clearer than yesterday.
Your photo never leaves your phone
Add a photo of younger-you
One picture from when you were small. It stays on your device — always.
Each habit lifts the veil
Two of four kept today? Two more pieces of her come into focus. No streak math.
By Saturday, she's whole
Keep your promises through the week and the full picture returns — yours to keep.
No childhood photo? A gentle silhouette — a chair, a window, a paper boat — reveals just the same. The point is showing up, not the picture.
Forgiveness, not streaks
Miss a day?
You're forgiven.
Every other tracker turns one missed day into a broken chain and a little jolt of guilt. We do the opposite. Miss a day and younger-you forgives you — gently, in her own words — and the picture waits right where you left it. You can't break this by living your life.
- She's still here
- Begin again
- No streaks to break
- Zero guilt
Most habit advice says don't miss twice. We built it so you can miss three times — and she's still here, still waiting.

Three voices
Who do you want
to hear from?
The nudges, the forgiveness, the Saturday letter — they all arrive in a voice you choose. Pick the one you need most right now. Change your mind whenever you like; there's no quiz to redo.

Younger-you
“I missed you yesterday.”
Warm, vulnerable, calls you by name.
Future-parent
“I knew you'd come back.”
Gentle, knowing — the parent you needed.
Best-friend
“Today's still yours.”
Warm, a little playful, always on your side.
No personality test to pass. The voice is yours to choose — and to change whenever you need a different kind of kind.
The Saturday reveal
Seven days.
The whole picture.
At the end of each week the veil lifts all the way. The full photo returns, your chosen voice writes you a short letter about the week you just had, and the app quietly saves a little reveal you can keep or share. It's the moment the whole thing is built around.
Not a report card. A letter — and it reads like someone who's proud of you. Because she is.

Letters across time
Write to her.
She writes back.
Some days you need more than a checkbox. Write a letter to your younger self, seal it, and choose the day it arrives. Write to the parent you're becoming. The replies land in an inbox that's only yours — sealed until the date you set.


“You wrote this a month ago. You said you'd be gentler with me this year. You were.”
Keep the ones that matter pinned to your home screen. Read them again on the hard days.
Promises to the world
When you're steady, love flows outward.
Once the daily habits stop feeling like a fight, a second arc opens: one-time promises to the people around you. Visit an older relative. Help a stranger. Show up somewhere that matters. No deadline, no streak — just a quiet record of the good you put back into the world.
The voices notice these too. Quietly, steadily proud.

Why it stays gentle
Built like a friend,
not a drill sergeant.
Forgiveness, not streaks
Miss a day and you begin again — no chain to break, no guilt, no jolt of shame.
Your photo stays private
Childhood photos live on your device. They're never uploaded, scanned, or used to train anything.
A voice that knows you
Younger-you, a future parent, or a best friend — the kindness arrives in the words you need.
Healed days, not streaks
It counts the days you showed up for her, framed as who you're becoming — never a score to protect.
FAQ
Gentle, honest answers.
- Is this therapy?
- No, and it doesn't pretend to be. Simple Habit Tracker is a gentle daily-habit app built on ideas from attachment and self-compassion research. It's a kind companion, not a clinician. If you're carrying something heavy, it'll quietly point you toward a real person who can help.
- What if I don't have a childhood photo?
- You don't need one. Pick a gentle silhouette instead — a small chair, a window, a paper boat — and it reveals the same way. The mechanic is showing up for younger-you, not the photo itself.
- Isn't the 'younger-you' idea a bit much?
- It can sound that way before you try it. In practice it's just a warmer frame around the same small habits — drink water, take a walk, go to bed on time. Turning a chore into a promise to someone you love is what makes it stick. And you can soften the framing any time in Settings.
- What actually happens when I miss a day?
- Nothing harsh. The picture waits, your chosen voice says something kind, and you pick up where you left off. There's no streak to break and no penalty — missing is part of being a person, and the app treats it that way.
- Is my photo or my writing ever uploaded?
- Your childhood photos stay on your device by default. Letters and notes are yours; an optional account syncs them across your own devices, encrypted. They're never read, scanned, or used for ads or AI training.
- Does it work offline?
- Yes. The daily habits, the mosaic reveal, and the forgiveness moments all run on your phone. An optional account just keeps things in sync across your own devices.
- Who builds Simple Habit Tracker?
- It's built and maintained by SimpleApps — the same one-person studio behind Simple Reminder, Simple Photographer 101, and Simple Gym. Indie, no investors, no dark patterns. simpleapps.ai.
