Pricing questions
Is there a free version?
Yes. Both apps are free to download on iOS and Android. Strelok Pro’s free tier gives you the solver with up to 3 saved rifles, and Strelok Internal Ballistics is free to try with the full published-load catalog. Upgrade any time for unlimited rifles and every ballistic feature; Range AI comes with Pro+.
Does one purchase cover every platform?
Mobile and Desktop are billed separately because they’re distinct products, and the desktop app signs in with a Strelok email and password. Rifles, loads and zeros sync between your phones and tablets; they don’t carry over to desktop yet, so you add them there once.
What does the lifetime option include?
A one-time purchase that unlocks the app for good: every ballistic feature in Strelok Pro ($79.99), or chrono calibration and Load Lab in Internal Ballistics ($29.99). Range AI is not included — it carries an ongoing inference cost, so it comes with a Pro+ subscription ($9.99/mo or $59.99/yr) on iOS and Android.
How do I get Partner API access?
Access is by request: there is no self-serve signup and no published rate. Keys for the hosted solve, truing and Monte-Carlo endpoints start at 60 requests a minute and 5,000 a day, with higher limits available. Tell us about your integration and expected volume and we’ll agree terms with you directly.
