Stop guessing what works for you. Run tiny real-life experiments: track a hypothesis, log what happened, and see what actually helped. Private and offline.
Field Trials is a private experiment journal for real life.
Use it when you are testing a recipe change, trying a gardening treatment, adjusting a routine, comparing a household setup, or running any small personal experiment you do not want to lose in scattered notes.
Start with a question, write a simple hypothesis, pick what you are changing, and choose one thing to measure. Each run can store the planned variable, what actually happened, metric values, notes, photos, voice notes, and a local check-in reminder.
When you have more than one run, Field Trials helps you compare what changed. It can summarize numeric metrics, show basic trends, and surface possible relationships without pretending messy personal data is proof.
Field Trials is built for casual experimentation, not professional lab work, medical tracking, or clinical advice.
What you can do:
- Create experiments for recipes, gardens, habits, household tests, learning projects, and more
- Capture hypotheses, protocols, variables, constants, and confounders
- Log repeated runs over days, weeks, or seasons
- Record numeric, scale, yes/no, category, and text metrics
- Save evidence photos and local voice-note backups
- Transcribe voice notes locally when supported by your device and language
- Delete audio while keeping the transcript
- Set local check-in reminders
- Compare runs, review metric changes, and write a conclusion
- Export your experiment as Markdown
