Hi Product Hunt — here's ShotSmith, a screenshot studio for indie app developers who want to keep their app screens on their own device. The full tool is one HTML file you download and open in your browser. Your screenshots are rendered locally, and you can use the downloaded tool offline. Add your screenshots, choose a background and an iPhone or Android frame, write captions, and arrange multiple slides. You can apply a style across the set and export individual PNGs or a ZIP of the slides. The portrait export presets include 1320 × 2868, 1290 × 2796, 1242 × 2688, and 2048 × 2732 pixels. The download costs $19 once. The free browser demo lets you try the editor before buying; demo exports include a watermark, which the paid version removes.
