SpawnLog: Mushroom Grow Log

The mushroom grow tracker built to replace your spreadsheet — and fix everything wrong with the other apps. 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 and weight, inoculation date, notes, and photos. The batch card shows total harvest, flush count, days running, and current BE% at a glance. Free up to 5 active batches. ▷ Flush Log & BE% — Always Free Record flush number, harvest date, wet weight, and dry weight. 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 / cobweb mold), stage (grain or bulk), date, discard status, and photos. Stay on top of what's failing and why. ▷ Harvest Share Cards — Free (with watermark) Tap share on any flush. A stats card is generated instantly: strain name, flush number, wet weight, dry weight, BE%, days since inoculation, and your harvest photo. Share it to Reddit, Discord, or Instagram. This is the card that makes other growers ask "what app is that?" SpawnLog Pro removes the watermark. ▷ Substrate Calculator — Always Free Two calculators built in: (1) Water Calculator — enter dry substrate weight and target moisture %, get exact water to add. (2) Spawn Rate Calculator — enter substrate weight and spawn rate %, get spawn weight. No more running Shroomery spreadsheets. ▷ Stats Charts (Pro) Bar charts for total harvest by batch, BE% by batch, and flush-by-flush yield trends. Contamination rate breakdown. See which strains and methods consistently win. ▷ Recipe Library (Pro) Save your substrate mixes with ingredient list and spawn rate. Link recipes to batches. 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. Import a CSV or ZIP anytime from Settings → Data to add records back. Compatible with Sheets, Excel, and Obsidian. 【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 r/MushroomGrowers, r/unclebens, or Shroomery · Growers who want their logs on their phone, not in some startup's cloud 【Your Data Stays on Your Device】 Everything is stored locally on your iPhone using SQLite.
