LetsGo iOS App: Native Swift Development for an 11-Country African Microfinance Platform
AppMatic Tech joined the LetsGo iOS development mid-stream, delivering native Swift iOS engineering for Letshego Holdings Limited, a company listed on the Botswana Stock Exchange serving 6.6 million consumers across 11 African countries. AppMatic Tech completed the iOS engagement in four months as part of a 200+ person cross-team delivery programme, aligning rapidly with the enterprise project structure and meeting all iOS release milestones.
The Challenge: Rapid Adoption of a Live Enterprise Programme at Scale, for One of Africa's Largest Microfinance Institutions
Joining the LetsGo iOS project mid-stream was a challenge of enterprise-scale alignment, not just technical delivery. Letshego Holdings Limited is a listed company on the Botswana Stock Exchange, with 6.6 million consumers across 11 African countries and a product that handles real loan applications, repayment tracking, and financial data for users in Botswana, Eswatini, Ghana, Lesotho, Namibia, Nigeria, Tanzania, Uganda, Rwanda, Mozambique, and Kenya. The LetsGo project was a 200+ person programme spanning multiple teams. AppMatic Tech was brought in mid-stream to own the iOS native layer in Swift and deliver releases within the programme's established timeline. The challenge was speed of adoption: assessing a production iOS codebase serving a multi-country listed company's consumer app, aligning with the delivery conventions and technical standards of a 200+ person programme, and shipping iOS releases on schedule without disruption to the broader project. AppMatic Tech completed the iOS engagement within four months, meeting the programme's delivery cadence throughout.
African Digital Lending App Landscape, Competitive Analysis
AppMatic Tech reviewed the African digital lending market as part of the LetsGo iOS engagement, understanding the competitive context in which Letshego Holdings operates across its 11-country footprint.
| Company | Unique Value Proposition | Company Advantage | Company Disadvantage |
|---|---|---|---|
 | AI-Powered Instant Mobile Loans: AI-powered instant mobile loans for underbanked users in Kenya, Tanzania, Nigeria, and India. | Fast Smartphone Data Scoring: Fast loan decisions via smartphone data scoring, no collateral or documentation required, active in multiple African markets. | Smaller Loan Sizes and Narrower Footprint: Smaller loan sizes than Letshego. No flexible repayment plan structure or transparent cost breakdown at point of application. Narrower African footprint than Letshego's 11-country operation. |
 | Smartphone Data-Based Micro-Lending: Smartphone data-based micro-lending in Kenya, Tanzania, Philippines, India, and Mexico. | Pioneer in East African Mobile Lending: Pioneer of mobile-first micro-lending in East Africa, strong brand recognition in Kenya. | Loans Only, Limited Geography: Limited product range: loans only, no broader financial services or referral programme. Geographic reach limited compared to Letshego's pan-African presence across 11 countries. |
 | Nigerian Digital Bank and Lending: Nigerian digital bank and lending app with bill payments, savings, and instant loan decisions. | Strong Nigeria Product Depth: Strong Nigeria-specific product depth with full digital banking features beyond lending alone. | Nigeria-Only Coverage: Nigeria-focused; no coverage in southern or eastern Africa. Cannot serve Letshego's user base in Botswana, Namibia, Lesotho, Eswatini, or the eight other Letshego markets. |
 | Dominant Mobile Money Platform: Dominant mobile money transfer and payment platform in East Africa with 50+ million registered users. | Largest Mobile Money Infrastructure: Largest mobile money infrastructure in Kenya and East Africa, high transaction volumes, strong brand trust. | Payments Platform, Not Lending: Mobile money and payments platform, not a dedicated lending institution. Loan product (M-Shwari) is secondary and smaller in scope than Letshego's microfinance-first offering across 11 countries. |

- iOS Native Application Development (Swift)
- AppMatic Tech developed and maintained the LetsGo iOS application in Swift, continuing from the existing iOS codebase and delivering new features and releases within the programme's sprint cadence.

LetsGo iOS Interface

LetsGo iOS App: Screen-by-Screen
AppMatic Tech delivered each of these screens in Swift within the four-month engagement, maintaining Letshego Holdings' design system and loan flow clarity across the full iOS feature set shipped to 6.6 million consumers.
Savings Dashboard and Product Discovery
The LetsGo home screen gives users instant access to savings products and loan categories from a single tap. The bottom navigation keeps core financial actions within thumb reach, while the product grid surfaces Letshego Holdings' full offering across savings, loans, and account services without requiring additional navigation steps.
Loan Eligibility and Amount Selection
On qualifying for a loan, the screen presents the user's maximum eligible amount with an interactive slider for selecting the exact borrowing amount, instalment frequency toggle, and real-time monthly repayment breakdown, so the user understands the full cost commitment before proceeding to application.
Application Review and Cost Confirmation
The loan confirmation screen presents the selected amount, term, and monthly cost with zero hidden charges before the user commits. A Discard Application option remains accessible throughout, ensuring the programme's commitment to transparent lending is visible at every step of the iOS application flow.
Guided Loan Process and Document Checklist
AppMatic Tech implemented the guided loan process view, which walks users through each stage of the Letshego application: apply online, get approved, access funds. The required document checklist presents identification, salary slip, and payment requirements in a scannable format that reduces incomplete application drop-offs across the 11-country user base.
Returning User Qualification Flow
The returning user flow surfaces the current maximum eligible amount with existing Letshego account context pre-loaded, reducing re-entry friction for repeat borrowers. AppMatic Tech engineered this state so the iOS experience matched Letshego Holdings' customer retention objectives across its pan-African consumer base.
Instalment Selection and Repayment
Lock-In
The final instalment screen lets users adjust repayment term and review the resulting monthly payment before committing. AppMatic Tech built the interactive slider and real-time repayment calculation so the iOS experience matched the cost transparency standard set at programme level across all Letshego Holdings' consumer touchpoints.
