CallCash

Most people get the call, get annoyed, and move on. The details are gone by the next morning. CallCash is built for the two minutes right after the phone rings, when you still remember what you heard. CallCash helps you keep a careful record of unwanted robocalls — and turn that record into a demand letter you can actually send. WHAT IT DOES - Log a call in seconds — number, time, what you heard, and your own notes - Answer plain questions about the call: artificial or prerecorded voice, signs of an autodialer, whether the line is a cell phone, whether your number is on the Do-Not-Call Registry, whether you ever gave or revoked consent - See which elements of the Telephone Consumer Protection Act your answers appear to satisfy, with the statute cited for each one - Flag the ones you want to assert — you decide, every time - Generate an editable demand letter naming the calls you flagged - Export a PDF evidence packet you can send, print, or hand to an attorney - Import a voicemail and attach a transcript to the call record BUILT AROUND YOUR OWN WORDS The analysis is not a black box and it is not a verdict. It is a set of plain-language questions, a rule for each statutory element, and a citation you can look up. Nothing is flagged unless you flag it. You are always the one asserting the facts, because you are the one who was there. YOUR RECORDS STAY ON YOUR PHONE No account. No sign-up. No password. No servers. No analytics, no tracking, no advertising. CallCash cannot read your call history — iOS does not permit that for any app — so every call in your log is one you entered yourself. It cannot record calls either. Voicemail transcription runs on your iPhone. If a recording is in a format the on-device transcriber cannot read, the app stops and asks before sending that one file to Apple's speech service. It never sends anything without your tap. FREE AND PREMIUM Free: log unlimited calls, flag violation elements, and generate one letter covering one call. CallCash Premium: unlimited demand letters, PDF evidence packet exports, and voicemail transcript attachments. $4.99 per month or $29.99 per year. Renews automatically unless cancelled at least 24 hours before the period ends; manage or cancel in Settings. IMPORTANT CallCash is a documentation tool. It is not a law firm. It does not provide legal advice, does not file anything on your behalf, does not represent you, and does not guarantee any outcome or payment. Statutory references are to public law (47 U.S.C. § 227). Consult a licensed attorney about your situation. Call-recording laws vary by state and some require the consent of every party. You are responsible for the legality of any audio you import.

Verdict
The clearest difference is in-app purchases: SFClock at none against CallCash's 2. SFClock also leads on device support (3 vs 1). CallCash's advantage is update cadence (every 2 weeks vs every 5 months). On price, ads and iOS requirement there is nothing between them.
