A field of grass that breathes with you. Breathe with it. Tap BREATHE and a pacer leads you through a slow breath — in, hold, out — and the whole field follows. The grass draws in toward you as you inhale and a gust rolls away from you as you exhale, so you pace your breath by watching a meadow instead of a shrinking circle. Three patterns: a long-exhale 4·6 for settling, box breathing, and 4·7·8 for sleep. Blow on the OUT to push the gust harder. The app keeps a quiet count of your sessions and breaths — no streaks, no reminders. Blow on it. Grass listens to the microphone — but only for breath. It knows the low rush of air on the mic from a voice or a song, so talking, music, and a noisy room leave the field still; a breath rolls a gust up through it. Blow hard and it flattens; stop and it settles back. Nothing is recorded — the app measures the moment and throws the sound away. Turn it. The wind comes from north. Real north — Grass reads your compass, so the field is oriented to the room you're standing in. Turn slowly and the blades swing to keep leaning away from magnetic north. Turn all the way round and the whole field lies down the other way. Comb it. Blades bend away from your finger and stay bent, and the field remembers every path you've traced through it. Use several fingers at once; each one combs its own way. Make it yours. Four scenes — a midsummer meadow, a dry straw field, a moonlit night, a first frost. A wind slider from dead calm to blustery. A breath sensitivity control. The pacer pattern. All behind a single quiet MENU. It moves in layers, not sheets. Long blades are a longer lever with more sail area, so they catch far more of a gust than short ones. The tall stuff lies over while the low stuff only stirs — the same reason a real field ripples instead of tilting all at once. Tens of thousands of blades, each one simulated individually, on the GPU. Between your breaths the natural wind is barely there — a field at rest, waiting for you. No score. No streak. Nothing to finish, nothing to miss. Grass makes no network connection of any kind, has no account, and collects nothing. Microphone and compass readings never leave your device.

Verdict

The call

The clearest difference is review sentiment: Grass at 100% against HISTORY Vault's 29%. Grass also leads on in-app purchases (none vs 4). HISTORY Vault's advantage is update cadence (monthly vs every 95 months) and rating (3.9 vs 3.7). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. HISTORY Vault sells 2 in-app purchases, starting at $5.99 per month. Grass asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

HISTORY Vault holds the better App Store score, 3.9 against 3.7. That said, the two scores are not equally well evidenced: HISTORY Vault has 1.1K ratings behind it against 202, so its average is the more settled of the two. Written reviews complicate that: 100% of Grass's written reviews are positive against 29% of HISTORY Vault's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Grass ships an update every 95 months, HISTORY Vault monthly. The most recent releases landed on October 22, 2026 and October 24, 2026 respectively.
