Mixed week
Reading recorded
20pages
12 on Monday + 8 on Thursday

Two entries. An imperfect week. The pages still count.

A day without an entry stays unknown. It is not automatically zero.

How it works

Your first week.

Real KYSTA screens with example data. Your goals, entries and results will be your own.

  1. 01

    Set your target

    Build a habit, do less or stop. Pick a goal idea or create your own goal and activities, then choose what to measure.

  2. 02

    Log what happened

    Eight pages read? Record eight pages. Add a note if you want the context. A day without an entry stays unknown.

  3. 03

    Review your week

    See what you actually did. In this example, two reading entries add up to 20 pages. An imperfect week still counts.

Evidence beats fragile streaks

Missed one? It still happened.

A streak can be useful, but one broken number is not your history. KYSTA keeps the work, keeps the miss and recognises the comeback. Failure remains visible; it does not erase earlier evidence.

Example week · one missed day1 missed day

The six days stay in the ledger. The seventh does not become a success. Your next honest entry becomes evidence of recovery.

Unknown is not zero.

No entry means no record. When you did none of a habit you want to reduce, explicitly log zero so your week tells the truth.

A miss does not erase the work.

Your previous entries stay in your history. Review what happened, adjust your target if needed, and keep going.

Your rules, stated plainly

Good shit. Bad shit. All of it.

Not every behaviour should go up. Not every goal is a streak. Choose higher, lower, or a useful range, and group one behaviour into every category it genuinely serves. Use a ready-made example or name and measure an entirely custom goal or activity.

Your record. Your call.

Your habits and notes are personal. Keep your record to yourself, or deliberately choose what you share. Export your data whenever you need it.

Reflective notes and short-text entries use field-level encryption at rest, not end-to-end encryption. KYSTA can decrypt them to show your entries and prepare your export.

Reward follows evidence

Evidence first. Rewards follow.

Reach a milestone, build consistency or make a comeback. Your rewards reflect what you recorded. These are examples of earned and locked artwork; your own collection follows your entries.

Earned rewards can be shared deliberately through your device's native share sheet. Notes and reflective text are never added to the share.
