Stackberry crafts lightweight, privacy-first apps that do one thing brilliantly — no bloat, no ads, no data harvesting.
Tools that respect your time, your money, and your privacy.
Track every bill, visualise your spending, and never miss a payment again. See what's due this week, next week, and beyond.
A contemplative prayer journal designed for stillness. Write, reflect, and track your prayer life with the warmth of an illuminated manuscript.
We don't collect data. Period. No analytics, no trackers, no accounts. Your information stays on your device.
Our apps are measured in kilobytes, not megabytes. No bloated frameworks, no unnecessary dependencies. Fast by design.
If an app lives on your device, you pay once and own it forever. If we run infrastructure for you, a simple monthly price keeps it running. No ads, no hidden costs.
A contemplative space for your prayer life — warm, quiet, and entirely yours.

Create groups to bundle related prayers together — for family, work, church, or any intention close to your heart.
Mark prayers as answered and record how God responded. Look back on your answered prayers for encouragement.
Build a gentle habit of prayer with a daily streak tracker. No pressure — just quiet encouragement to show up each day.
Start each session with a scripture verse to centre your heart before you begin writing.
