SpawnLog: Mushroom Grow Log

Cultivation Tracker & BE% Calc

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

For mushroom growers who want more than a spreadsheet. Batch logs, flush records, BE% auto-calculated. Harvest share cards. One-time purchase — no subscription. The mushroom grow tracker built to replace your spreadsheet. Every flush logged. Every harvest weighed. BE% calculated automatically. No locked logs, no subscription, no cloud required. 【What You Can Do】 ▷ Batch Tracking Log every batch from inoculation day: species, strain, substrate type, dry substrate weight, inoculation date, notes, and photos. The batch card shows total harvest, flush count, days running, and current BE% at a glance, and the timeline puts every flush and contamination in date order. Free up to 5 active batches. ▷ Flush Log & BE% — Always Free Record flush number, harvest date, wet weight, notes, and photos. SpawnLog calculates BE% (biological efficiency = wet weight ÷ dry substrate weight × 100) automatically — the metric every serious grower tracks. Every log is fully editable and deletable. No locked entries, ever. ▷ Contamination Log Record contamination type (green mold / wet rot / bacterial blotch / other), stage (agar, grain, or bulk), date, notes, and photos. Stay on top of what's failing and why. ▷ Harvest Share Cards — Free (with watermark) Tap share on any flush or batch. A card is generated instantly with your harvest photo and the stats you choose — yield, BE%, days since inoculation, strain, and more — in square, portrait, story, or landscape. Share it on social media or with your grow community. SpawnLog Pro removes the watermark. ▷ Substrate Calculator — Always Free Two calculators built in: (1) Water Content — enter dry substrate weight and target moisture %, get the exact water to add. (2) Spawn Rate — enter substrate weight and spawn rate %, get the spawn weight. No more spreadsheet formulas. ▷ Archive Reminders Get a notification when a batch has had no flush log for 60 days, so your active list stays clean. ▷ Stats Charts (Pro) Bar charts for total harvest by batch, BE% by batch, and harvest by flush number, plus contamination by stage. See which strains and methods consistently win. ▷ Recipe Library (Pro) Save your substrate mixes with ingredients, notes, and spawn rate. Never forget what you used in that record-breaking run. ▷ Export & Import — Always Free Export batch and flush data as CSV, or as a ZIP that includes photos, notes, contamination logs, and recipes — as a backup or when moving to a new iPhone. Import a CSV or ZIP anytime from Settings → Data to add records back. CSV files open in spreadsheet apps such as Excel. 【Who It's For】 · Home growers managing multiple batches who've outgrown paper and spreadsheets · Anyone who's ever asked "what was my BE% on that oyster run last month?" · Growers who post harvest results on social media or in online grow communities · Growers who want their logs on their phone, not in the cloud 【Your Data Stays on Your Device】 Everything is stored locally on your iPhone. Nothing is sent to external servers. No account required. No subscription. No risk of losing your grow history if a service shuts down. 【Pricing】 · Free: 5 active batches, flush logs, contamination logs, BE% calculation, substrate calculator, CSV/ZIP export & import, and share cards (with SpawnLog watermark). · SpawnLog Pro (one-time purchase): Unlimited active batches + stats charts + recipe library + watermark-free share cards. Pay once, yours forever. ---------------------- Developer: Kore Apps Contact: support@kore-apps.com ----------------------
