DwellLog

Walk the property. Record what you can see, then seal it before it drifts. DwellLog turns a home walkthrough into a dated, tamper-evident record. Pick an area. Name the component and a location you can return to. Write what is directly observable, rate the condition, and seal the entry. Each seal is a SHA-256 digest, so a later reader can tell whether a record or its photo changed after you saved it. Work the eight survey areas: site and drainage, exterior envelope, structure, water and plumbing, electrical, climate and mechanical, interior, and life safety. Add a measurement when you have one. Note the weather, the viewing position, and anything you could not reach. Revisit the same location next season. DwellLog keeps the original and files your update as a superseding record instead of overwriting it, then shows what is new, improved, or worse. Open a case when something needs action. State the risk in a sentence, set a next step, give it a target date, and link the evidence. Close it with a dated event, never a silent edit. Log the furnace and water heater. Photograph the serial plate. Record brands, models, warranty dates, and cost. Add recurring maintenance from the catalog, log each service with its provider and price, and read the annual cost report. Share a readable evidence packet and a machine-readable manifest of record and photo digests with a buyer, tenant, contractor, or your own files. Export runs only after every seal and supersession link passes. DwellLog is a recordkeeping tool, not an inspection. It does not diagnose defects, determine cause, or certify compliance. Keep every record yours: no account, no server sync, no third-party analytics.

Verdict
The clearest difference is price: Control at Free against DwellLog's $1.99. Control also leads on update cadence (every 5 days vs every 3 weeks). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
