What each plan actually gets you
Astro — $9/month, billed annually
A Mac-only desktop app (macOS 14+) covering the iOS App Store only. For $108/year flat you get unlimited keyword tracking with popularity and difficulty scores, keyword suggestions, rankings, competitor analysis, and 60+ countries. Held back: nothing by tier — there's only one plan. The constraints are scope: no Android, no analytics or review tooling, and you need a Mac.
Appfigures — Connect $9.99/mo or Monitor $44.99/mo
The pricing page also lists a free Starter plan. Connect adds 25 tracked keywords on top of Appfigures' core strength: downloads, revenue, and subscription analytics across both stores for 5 apps (then $1.99/app). Monitor raises that to 100 keywords with daily rank updates and keyword popularity scores. Held back: competitor keyword tracking and real-time keyword analysis sit on Optimize at $149.99/mo — just over our line.
MobileAction — Lite $15/mo or Basic $69/mo
Lite is one of the cheapest cross-platform entries anywhere: 100 keywords, 5 apps, 3 competitors per app, 3 months of history. Basic steps up to 500 keywords, 8 apps, 10 competitors per app, and 6 months of history — the most apps under $100 on this list. Held back: 12-month history, 3 seats, and 1,500 keywords need Pro at $239/mo; ad intelligence products are custom-priced.
ASOMobile — ASO Indie, $59/mo ($47/mo annually)
A plan literally named for us: 500 keywords, 5 apps, 50 competitors, 500 review replies, and 1,000 API credits, with keyword research, competitor reports, and branded keyword tracking. Held back: the AI editor, description text editor, competitor tracking, and keyword complexity/effectiveness indices need Pro at $119/mo; visibility scoring and Apple Search Ads analysis sit higher still.
Asodesk — Pro, $59/mo
The biggest keyword cap under $60: 700 keywords, 200 competitor apps, and 2 teammates — but only 2 apps and 100 review replies/month. There's also a permanent free plan (200 keywords, 1 app). Held back: 3,000 keywords and 10 apps need Guru at $199/mo, and heavier review automation is priced as a separate Reply-to-Reviews product line.
App Radar — Essentials, €69/mo (€58/mo annually)
Note the currency — App Radar (by SplitMetrics) prices in euros: 2 apps, 500 keywords, 25 competitors, 1 seat. The 7-day trial requires a credit card and auto-converts unless you cancel. Held back: 10 apps, 1,500 keywords, and a second seat need Growth at €169/mo.
AppTweak — Essential, $79/mo
The premium name that still fits the budget: 500 keywords, 1 seat, 6 months of history, 12+ keyword research tools, live searches, competitor analysis, app page preview, and a reporting studio. Held back: the flashiest data — organic installs per keyword, keyword impact analysis, metadata simulator, trending keywords — needs Grow at $299/mo. That's a steep cliff, so make sure Essential's feature set is the one you actually want.
Pick by situation
One app, nights and weekends
If it's iOS and you own a Mac, Astro at $9/mo is almost impossible to argue with — unlimited keywords for less than two coffees. Cross-platform, Appfigures Connect at $9.99/mo pairs starter keyword tracking with genuinely good revenue analytics. And honestly? If you're pre-revenue, the free options may be all you need this year.
One app that's earning money
You want 500+ keywords and real competitor tooling. MobileAction Basic ($69) and AppTweak Essential ($79) are the strongest all-rounders; Asodesk Pro ($59) gives you the most keywords per dollar if two apps is enough.
A small portfolio (3–8 apps)
App caps matter more than keyword caps now. MobileAction Basic covers 8 apps for $69; ASOMobile ASO Indie covers 5 for $59 with review replies included. If revenue reporting across the portfolio matters as much as keywords, Appfigures Monitor ($44.99) covers 5 apps and scales at $1.99 per extra app.
Three watch-outs before you subscribe
- Advertised prices are often annual-billing prices. ASOMobile's $47 and App Radar's €58 require paying for the year; the monthly figures above are what you'd pay month-to-month.
- Mind the cliff to tier two. AppTweak jumps $79 → $299; Asodesk $59 → $199. Check whether the feature you'll want in six months is on this side of it.
- Trials that auto-convert (App Radar takes a card up front) deserve a calendar reminder on day one.
When under $100 stops being enough
Usually one of three things: you're localizing across many markets and blow through 500-keyword caps; you need install-per-keyword attribution to justify paid UA; or you've added teammates and every tool wants $100+ for a second seat. Until then, the plans above cover a full indie ASO loop: research, track, iterate, respond.
Where Kintsu fits
Kintsu is a mobile-app intelligence platform in private beta, built for indie developers and small studios — the same audience these plans serve. It brings unified analytics across App Store Connect, Google Play, and ad networks together with ASO keyword tools, AI-assisted review management, store screenshot generation, and competitor monitoring in one place. Founding-cohort seats (100 total) are open at thekintsu.com.
