- Subscription Hunter
Subscription Hunter helps you see the real cost of your subscriptions, not the number you guess. Most people underestimate recurring spend. Research found consumers thought they paid about $86 a month, but averaged $219 when they listed every charge, roughly 2.5× higher. If that sounds familiar, this tool was built for you.
Open the free subscription cost calculator and tap the services you already pay for: Netflix, Spotify, ChatGPT, Disney+, YouTube Premium, cloud storage, design tools, and 50+ more. Missing something? Add a custom subscription with a name and monthly price. In about a minute you get monthly, yearly, and 5-year totals, plus a category breakdown so you can see where the money actually goes.
There is no signup and no bank login. Nothing is stored unless you later choose to join the Subscription Pilot waitlist. After the hunt, export a one-page PDF with your stack score, totals, and insights. Keep it for yourself or share it when you want a clear snapshot of your recurring expenses.
Subscription Hunter is for anyone who wants a fast, private way to check subscriptions, understand average monthly cost for their own life, and stop guessing. Dream outcome: know your real number. Time: about a minute. Effort: tap apps you recognize. Result: clarity on what you pay now and what that spend becomes over five years.
If you want every recurring charge from a bank statement, including services not on the list, join the Subscription Pilot waitlist and scan a CSV. Still no bank login required. Start with Subscription Hunter today and see your stack total before the next billing cycle surprises you.

- Nearer
Nearer replaces the wall of unfinished work with a single card. Add tasks, repeatable routines, or flashcards, then work through them one at a time. Routines can reset daily, weekly, monthly, yearly, manually, or upon completion. It is for people who feel overwhelmed by conventional long lists and want a quieter way to start and continue. It deliberately is not a project-management dashboard or a bird's-eye view of every obligation.
- Crawlready
CrawlReady is the AI interface layer between your website and AI crawlers. GPTBot, ClaudeBot, PerplexityBot, and Bytespider fetch pages over plain HTTP — no JavaScript — so React, Vue, and Angular sites hand them an empty <div id="root">. CrawlReady detects verified bot traffic, renders the page at the edge, injects LLM-optimized Schema.org, and serves the format each client reads best. Live today: AI crawler analytics, an AI Readiness Score for any URL, and one-line integration for Next.js, Express, and Cloudflare Workers. Human visitors see zero difference. Free to start, no signup required to scan.

- Veldo
Veldo is a native Mac app that does the join. It tracks organic App Store rank across 60+ storefronts, pulls your Apple Search Ads spend and installs, and optionally connects RevenueCat for attributed revenue.
Every keyword lands on one row with a plain verdict: double down, bid opportunity, cannibalizing, or money pit, with the numbers behind it.
It also covers the rest of the loop: reverse ASO to find what any app really ranks for, keyword gap against competitors, a metadata editor with live character counts and coverage, custom product page advice, review tracking, and notifications when a verdict flips.
Everything runs locally. Rankings, spend, revenue, and credentials stay in a database on your Mac, with API keys in the macOS Keychain. There is a CLI and a read-only MCP server, so your scripts and AI agents. can query the same data.
$8.99 a month or $99 a year. A flat tool fee, not a percentage of your ad spend, with unlimited apps and keywords and a 14-day money-back guarantee.
- Marksy
Save bookmarks, and let AI group them by topic automatically. Export back to Chrome as neatly organized folders in one click. No tags, no manual sorting, no clutter. Try your first month of Marksy Pro for just $1.
- Finngarden
Finn Garden is a public workshop for small products. They get shipped, run in the real world, and everything learned along the way gets published : the tactics that worked, the ones that flopped, and the numbers behind both.
It all comes from actual launches, not theory. Build articles: honest tool comparison, stack breakdowns, what holds up in production. Marketing playbooks: cold email, follow-up sequences, distribution and SEO/GEO experiments. Plus behind-the-scenes updates on the products themselves.
If you're a solo founder, indie hacker or maker who'd rather learn from someone else's wasted months than repeat them, the newsletter sums up what's working right now. No fluff, no recycled advice. Everything is free to read.
