ENGAGEMENT
Pricing & engagement
We don't publish a rate card — complexity varies too much per project for a made-up number to be fair to either side. Send us your requirements and within 30 minutes you'll have a figure written into the contract.
1Describe the job
Message us the background and goals; attach source files or references for a sharper estimate.
2Quote in 30 min
A fixed total and schedule based on workload × complexity. If it's not a fit, no hard feelings.
3Fixed-price contract
The total goes into the contract; 50% to start. Bank transfer and official invoicing supported.
4Pay on approval
The balance only after you approve. Full source files, plus 7 days of free tweaks.
How do you price app development?
A fixed price by feature list and stack choice, quoted within 30 minutes with a schedule. No increases after signing; the cost difference between cross-platform and native is spelled out at assessment.
Native or cross-platform?
Choose native for performance and system depth (camera, push, motion); choose Flutter / uni-app for tighter budgets and simultaneous dual-platform launch. We give a clear recommendation — with reasons — at assessment.
What does store release require?
Usually software copyright registration, a privacy policy, filing information and store account materials. We provide the checklist and technical support through submission.
