Android File Sync Tool

Fast, local-first file transfer between computers and Android devices over USB or Wi-Fi without cloud dependency. Solves the friction of transferring files for Android developers and power users.

Android's persistent file transfer friction is real — MTP remains broken on Windows, and ADB-based workflows are clunky enough that developers regularly reach for workarounds. LocalSend exists as a free, open-source cross-platform transfer tool with significant traction, which is the most direct substitute and the most immediate problem: competing against a well-regarded free tool means the paid version needs a clear workflow advantage (speed, dev-specific integrations, automation) that average users won't pay for. The $500–2k/mo band is plausible only if the target stays tightly scoped to developers or IT admins managing device fleets, where willingness to pay for reliability exists, not general consumers. The most likely failure mode is the market being too small once the free alternatives are accounted for — power users who need this badly enough have already solved it with rsync over ADB or LocalSend, and the remainder aren't paying $5/mo for file transfer.
