Launching soon on Google Play — 10 languages, 7 conditions supported, fully offline

あなたのスマートフォンから決して出ていかない周期・神経多様性トラッカー

Cycle, pregnancy, postpartum, perimenopause, and TTC tracking — alongside real tools for autism, ADHD, dyslexia, dyspraxia, OCD, and Tourette's. Not a single generic checklist bolted onto a period app.

Get notified at launch See what it tracks

No account. No server. Nothing collected — by design, not by promise.

Built the way we'd want it built for someone we love

Not a checklist of features — three things we refused to compromise on, because we were building this for real women, not a user persona.

What you log is yours, full stop

No cloud sync by default, no account to breach, nothing quietly shaping an ad profile. Your data stays on your phone unless you decide otherwise — not a setting to dig for, the actual default.

Taken seriously, not simplified

Seven life stages that genuinely differ from each other, and neurodivergence support grounded in real clinical guidance — because you deserve a tool that respects how complicated a body and a mind actually are.

One subscription, nothing locked away

Every life stage, every condition, included from day one. No "premium tier" gatekeeping the features you actually need most — that's not a kindness, it's just how it should work.

すべてのライフステージ

どの段階でも、1つのアプリで

生理と周期

出血量、血の塊、症状、そして実際にあなたがいるフェーズ — 固定の28日周期の想定ではなく、あなた自身の記録履歴から計算されます。

  • Phase-aware calendar
  • Symptom & flow logging
  • PMDD pattern detection across tracked cycles

妊活とTTC

基礎体温、頸管粘液、排卵検査、そしてあなたの妊娠可能期間 — 妊活のためにも、周期をよりよく理解するためにも。

  • BBT & cervical mucus logging
  • Fertile-window calculation
  • Ovulation test tracking

妊娠

週ごとの進み具合、症状、診察予定 — すべての三半期を通じて。

  • Week-by-week milestones
  • Symptom & appointment log
  • Switches automatically from cycle mode

産後

検証済みの気分スクリーニング（EPDS） — 当て推量ではありません — さらにACOGに基づいた母乳育児の栄養ガイダンスも。

  • Edinburgh Postnatal Depression Scale screening
  • Breastfeeding nutrition guidance
  • Recovery tracking

周閉経期

周期の長さの変動を実際のシグナルとして — ほとんどの女性には不要なホルモン血液検査ではなく、NICEのガイドラインに沿っています。

  • Cycle-length variation flagging
  • Symptom tracking
  • No test required to get started
Cycle & life stages

Every stage you'll actually move through

Cycle tracking that adapts as your life does — pregnancy, postpartum, perimenopause, and trying-to-conceive mode, each with its own real tracking, not a generic wrapper around the same four fields.

Neurodivergence

Six conditions, not one checklist

Autism, ADHD, dyslexia, dyspraxia, OCD, and Tourette's — each one adds its own relevant fields (tic frequency, compulsion burden, reading fatigue, coordination) on top of four fields every ND user gets regardless of which conditions apply: sensory load, masking, burnout, and gut symptoms.

A little world that grows with you

Logging anything earns coins toward a genuinely large collectibles system — hundreds of plants and companions, built from scratch, not bought in. It's there because showing up consistently is hard, not to manufacture a guilt-trip streak.

Privacy & sharing

Private by default, shared on your terms

Everything stays on your device unless you decide otherwise. Create an encrypted backup wherever you want, or share a limited, chosen slice with a partner — never through our servers, because none exist. See exactly how: the encryption, partner sharing, or exporting your data.

Our research

We didn't guess which fields actually matter

From tic frequency to perimenopause cycle changes, every field the app treats as important is grounded in real clinical research, not an assumption made to fill a screen.

Little Greenhouseを選ぶ理由

本当に違いを生む点

一つだけでなく、すべての段階に

生理、妊娠、産後、周閉経期、妊活 — アプリはあなたが実際にいる段階に寄り添い、一つを標準とみなして残りを二の次に扱うことはありません。

後付けではない神経多様性の記録

自閉症、ADHD、ディスレクシア、発達性協調運動症、強迫性障害、トゥレット症候群の6つの専用特性 — それぞれが臨床的根拠に基づく独自の項目を持ち、すべてに引き伸ばされた単一の汎用チェックリストではありません。

「なんとなくプライベート」ではなく、本当にオフライン

アカウントなし、クラウド同期なし、広告ネットワークへの通信なし。オンにする設定ではありません — そもそもあなたのデータが行く場所がないのです。

すべての主張に、出典あり

12の研究ページ、それぞれが実在する日付入りの研究に脚注でリンクしています — 裏付けのない曖昧な「臨床的に裏付けされた」バッジではありません。

Why this exists

This started with a worry, not a business plan

My girlfriend used to track her cycle the way most people do — one of the big apps, the same ones almost everyone has. What bothered her wasn't the tracking itself. It was watching those apps keep asking for more, and then finding out some of that data had been sold.

So Little Greenhouse is built the only way that actually answers that worry: nothing leaves your phone unless you decide to send it somewhere yourself. Not stored on our side, not synced to an account, not sitting on a server somewhere waiting to become a dataset. There's nothing to sell, because there's nothing here to collect in the first place.

Concretely, that means:

Nothing you log is training an AI model you never agreed to.

Sharing with a partner is something you choose and control — not a standing door left open.

Your health data was never a product to be sold in the first place.

Why leave them

If you're already using Flo, Clue, or Period Calendar

Here's what actually changes, compared directly against each app's own listed features and pricing — not a generic "other apps" stand-in.

Pricing and features per each app's own official Google Play / App Store listing, checked October 2026 — regional pricing varies; USD shown as each app's own reference figure. "Dedicated ND tracking" means built-in, clinically-grounded fields for specific conditions (tic frequency, compulsion burden, and similar) — none of the three list this as a feature. Period Calendar Period Tracker (100M+ installs, 4.9★ on Google Play) is the only one of the three that runs on ad revenue rather than subscriptions, and its listing confirms it serves ads; it offers encrypted backup, but through a Google account rather than a self-held passphrase, which is why that row is framed around account-dependence rather than encryption itself.
