LemSubs vs Stackerr
LTD-focused tracker with buying scores and failure rates — but limited to lifetime deals only
Stackerr (by Prime Club) is a niche tool built specifically for lifetime deal (LTD) buyers. It focuses on tracking your LTD purchases across marketplaces like AppSumo, PitchGround, DealMirror, and StackSocial. Its standout features are a 'Buying Score' that rates your purchase discipline, failure rate tracking across platforms, and a Chrome extension that lets you add LTDs with one click while browsing deal sites.
Stackerr also sends refund reminder emails before windows close — a genuinely useful feature for impulsive buyers. However, Stackerr is exclusively focused on lifetime deals. It doesn't track recurring subscriptions (monthly/annual SaaS), doesn't offer renewal calendars, has no overlap detection, no team features, and no category budgets.
If you only buy LTDs, Stackerr does that one thing well. But most people have a mix of LTDs and recurring subscriptions — and that's where LemSubs shines. LemSubs tracks everything: one-time purchases, monthly subscriptions, annual plans, credit-based tools, and free trials.
It adds health scoring, redundancy detection, smart insights, refund window tracking, and a full spend analytics dashboard. Think of it this way: Stackerr is a specialist tool for LTD collectors; LemSubs is a complete subscription command centre that also handles LTDs with equal or better intelligence.

Frequently asked questions
Is Stackerr better than LemSubs for lifetime deals?
Stackerr is purpose-built for LTDs and has a nice Chrome extension for quick adding. However, LemSubs matches or exceeds its LTD features (defunct tracking, buyer score, refund windows, platform breakdown) while also tracking all your recurring subscriptions, offering health scores, overlap detection, and 18 smart insight rules.
Does LemSubs track LTD failure rates like Stackerr?
Yes — LemSubs tracks defunct subscriptions per platform with detailed reasons (shutdown, acquired, pivoted, scam), refund recovery tracking, and even warns you when a platform has a high defunct rate among your purchases.
Does LemSubs have a Chrome extension?
Not currently — LemSubs focuses on its web app with PWA support (installable on any device). Stackerr's Chrome extension is useful for adding deals while browsing marketplace sites.
Can I use both Stackerr and LemSubs?
You could, but there's significant overlap. LemSubs covers everything Stackerr does (LTD tracking, buyer scores, refund reminders, defunct tracking) plus recurring subscriptions, analytics, and team features. Most users find LemSubs sufficient on its own.
How does the Buyer Score compare between the two?
Stackerr's Buying Score measures purchase discipline. LemSubs's Smart Buyer Score is more comprehensive with 4 weighted components: active-use ratio (35pts), cost efficiency (25pts), refund discipline (20pts), and defunct penalty (20pts). LemSubs also tracks buyer score trends over time.
Does Stackerr support recurring subscriptions?
No — Stackerr is exclusively for lifetime deals. If you have monthly or annual subscriptions (Netflix, Slack, Adobe, etc.), you'll need a separate tool. LemSubs handles both in one place.
